WARNING  
Only Hughes-certified installers may install or service  
Hughes earth stations and components. Installers must  
expressly acknowledge the Hughes requirements for  
Hughes installations.  
DANGER  
If you work on a roof, tower, or other high structure or use a  
ladder or scaffold to access the work site, follow these  
precautions to prevent personal injury or death:  
• Walk only on sound roof structures.  
• Make sure the antenna assembly and installation  
surface are structurally sound so they can support all  
loads (equipment weight, ice, and wind).  
• Use appropriate safety equipment (for example, a  
lifeline), depending on the work location.  
• Follow all safety precautions from the manufacturers of  
all safety equipment and other equipment used.  
• Perform as many procedures as possible on the ground.  
DANGER  
• To avoid electric shock, stay at least 20 ft from power  
lines.  
• If any part of the antenna or mount assembly comes in  
contact with a power line, call your local power  
company to remove it. Do not try to remove it yourself.  
Failure to heed these warnings could result in serious injury  
or death.

WARNING  
• Do not work in high wind or rain or if a storm, lightning,  
or other adverse weather conditions are present or  
approaching.  
• Do not attempt to assemble, move, or mount the  
antenna on a windy day. Even a slight wind can  
unexpectedly create strong, unexpected forces on the  
antenna surface.

CAUTION  
Observe these precautions to avoid exposure to RF  
radiation, a potential safety hazard:  
• The antenna must be installed in a location or manner  
not readily accessible to children and in a manner that  
prevents human exposure to potentially harmful levels  
of radiation.  
• Antennas mounted in Puerto Rico, the continental  
United States, or at any site with greater than a 30°  
elevation angle must be installed such that the lower lip  
of the antenna reflector is at least 5 ft above any surface  
upon which a person might be expected to stand, and  
3 ft 3 inches from any opening (such as a door or  
window) in a building or adjacent structure.  
• Antennas mounted in Canada, Alaska, Hawaii, or any  
site with less than a 30° elevation must be installed  
such that the lower lip of the antenna reflector is at least  
5 ft 9 inches above any surface upon which a person  
might be expected to stand, and 3 ft 3 inches from any  
opening (such as a door or window) in a building or  
adjacent structure.  
• The antenna must be mounted such that no object  
which could reasonably be expected to support a  
person is within 6 ft 7 inches of the edges of a  
cylindrical space projecting outward from the antenna  
reflector toward the satellite.  
• If the above distance requirements cannot be met, the  
antenna must be mounted in a controlled area  
inaccessible to the general public, such as a fenced  
enclosure or a roof.  
• The antenna must be mounted such that there is no  
object outside the controlled area which could  
reasonably be expected to support a person within  
6 ft 7 inches of the edges of a cylindrical space  
projecting outward from the antenna reflector toward  
the satellite.  
• A fenced installation must have a locked entry, and the  
fenced area must be large enough to protect the general  
public from exposure to potentially harmful levels of  
radiation.  
• Access to a roof installation in a commercial, industrial,  
or institutional environment must be limited by a door or  
a permanently fastened ladder that is locked to deny  
access to the general public.  
Failure to observe these cautions could result in injury to  
eyes or other personal injury.

CAUTION  
• All installations of any type or size must carry an  
industry standard and government approved Radiation  
Hazard Caution label on the feed arm.  
• A fenced or roof installation in a commercial, industrial,  
or institutional environment must carry a Radiation  
Hazard Caution sign on the access door, gate, or  
permanently mounted access ladder that is within plain  
sight of anyone approaching the antenna from the front  
or sides of the reflector.  
Failure to observe these cautions could result in injury to  
eyes or other personal injury.  
Some installations may require additional precautions. See also  
the HN System Antenna Site Preparation and Mount  
Installation Guide (1035678-0001).

This section explains where you can find information on tasks  
related to antenna installation.  
Tasks related to antenna  
installation  
Factors you should consider in selecting an installation site are  
discussed in the HN System Antenna Site Preparation and  
Mount Installation Guide (1035678-0001). The installation site  
and mounting method may be specified in the customer-specific  
installation specification.  
Selecting the installation  
site  
A suitable antenna mount must be installed before the antenna  
can be installed. Acceptable mounting methods are:  
Installing the antenna  
mount  
• Non-penetrating mount  
• Trimast (may be used on a wood-frame roof or wood or  
masonry wall)  
• Pole or pedestal mount  
Most installations in a commercial, industrial, or institutional  
environment use a non-penetrating roof mount.  
For pole or pedestal mounts that require a concrete base, you  
must allow at least 24 hr for the concrete to cure before you can  
install the antenna. Plan accordingly.  
For complete information concerning antenna mount installation,  
refer to:  
• The customer-specific installation specification  
• The HN System Antenna Site Preparation and Mount  
Installation Guide  
The customer-specific installation specification may include  
customer-specific guidelines concerning mount installation. Use  
only the mounting method described in the specification. For  
mount installation instructions, see the HN System Antenna Site  
Preparation and Mount Installation Guide.  
See the installation manual for the IDU (also referred to as a  
remote terminal.)  
Installing the IDU  
Grounding  
The entire antenna assembly must be grounded. For grounding  
information, refer to your training; best grounding practices; the  
Hughes Field Service Bulletin (FSB), HNS Broadband  
Requirements for RG-6 and RG-11 IFL Cable Connectors,  
Ground Blocks and Ground Block Location (FSB 50518_01C);  
and applicable parts of the National Electrical Code (NEC).

For a list of approved cables for the interfacility link (IFL)  
between the antenna and the remote terminal, see the Hughes  
FSB, IFL Cable, Approved List (with lengths) for DW7x00,  
DW60xx, and DW40xx Domestic Installations  
Approved cables  
(FSB_060316_01A). The FSB lists the maximum cable length  
for each approved cable type, for both 1-W and 2-W radios.  
How the cable is run depends on the specific installation site.  
Route and connect the IFL cable according to your training and  
best practices.

The feed support tube and the feed rods are the only main parts  
included in both antenna kits that are different.  
Feed horn and waveguide The feed horn (Figure 7) transmits and receives signals to and  
transition from the reflector.  
The J-type radio assembly requires a waveguide transition, as  
shown in Figure 7. In the antenna kit for the J-type radio, the  
transition is attached to the feed horn at the factory, as shown in  
Figure 7. As explained later in this manual, you attach the  
transition the radio assembly.  
The antenna kit for the cradle-type radio does not include a  
waveguide transition because the feed horn attaches directly to  
the cradle-type radio assembly.

The radio assembly is not part of the antenna kit; however, radio  
assembly installation is included in this manual because the  
antenna and radio assembly are usually installed at the same time.  
There are two possible radio assemblies available for the .98 m  
antenna, the J-type radio assembly or cradle-type radio assembly.  
Radio assembly types  
J-type radio assembly Figure 10 shows the J-type radio assembly, referred to as J-type  
because its waveguide is shaped something like the letter J.  
J-shaped  
waveguide  
Figure 10: J-type radio assembly  
J-type refers to the overall design of the radio; therefore, two  
radios with different model numbers may both be J-type radios.  
Vertical shim kit (if required)  
A vertical transmit shim kit may be required for the J-type radio  
assembly only. If the installation specification states that vertical  
transmit polarization is required, you will need to obtain and  
install a vertical shim kit (Figure 11) in the radio assembly.  
Otherwise, a vertical shim is not required. For more information,

page 32.  
Figure 11: Shim for vertical transmit polarization  
Cradle-type radio assembly Figure 12 illustrates the cradle-type radio assembly. The main  
parts of the radio assembly are mounted on two circular brackets  
so they can be rotated, similar to the movement of a cradle, to set  
the polarization of the feed horn. The arrows in Figure 13 indicate  
how the radio assembly can be rotated.

Chapter 3  
Assembling the antenna  
This chapter explains how to install:  
• The Az/El and reflector bracket assembly – The Az/El  
mount assembly and reflector bracket assembly are  
pre-assembled for installation as a single unit, as shown in  
Figure 3 on page 10.  
• The antenna reflector  
• The feed rods and feed support tube – The feed rods attach  
to the reflector and help support the feed support tube.  
Radio installation is covered in Chapter 4 for the J-type radio and  
Chapter 5 for the cradle-type radio.  
Topics in this chapter include:  
• Determining the pointing values on page 21  
• General instructions for assembling the antenna on page 22  
• Installing the Az/El and reflector bracket assembly on  
page 23  
• Attaching the reflector on page 25  
• Installing the feed support tube on page 27  
CAUTION  
Before you install the antenna, read all safety information in  
the section titled Important safety information on page iii.  
Satellite-based commissioning (SBC) is an automated web-based  
method for pointing the antenna. SBC configures the IDU,  
calculates its exact location, and uses the location and other  
information to help you point the antenna. SBC calculates the  
values you use to set the antenna’s azimuth, elevation, and  
polarization, based on the information you enter and the satellite  
you select. It then downloads the necessary software and  
completes the IDU registration process.

In this manual, installation software refers to installation,  
pointing, and commissioning software accessed through the IDU,  
which works in conjunction with SBC.  
Before proceeding, use the installation software to determine the  
initial values to use for setting azimuth, elevation, and  
polarization. Record these values and keep them handy for  
reference as you install and point the antenna. To use the  
installation software, follow the instructions in the IDU  
installation manual for commissioning the IDU.  
Before you assemble the antenna, read these important  
instructions:  
General instructions for  
assembling the antenna  
• Mast – The mast must be installed before you can install the  
antenna. For information on antenna mounting methods, see  
the HN System Antenna Site Preparation and Mount  
Installation Guide (1035678-0001). The mast must have an  
outside diameter of 2-3⁄8 inches (2.375 inches).  
• Sequence of steps – When you assemble the antenna, follow  
the instructions in this chapter in the order they are  
presented.  
• Tightening hardware– Do not tighten any nuts or other  
hardware until you are instructed to do so. (See also the next  
item, Torque.)  
• Torque – To ensure successful installation of the antenna, you  
must tighten all nuts and socket-head cap screws to the  
maximum torque values shown in Table 6. This is a critical  
requirement.

For bolts that use a split lock washer, tighten the bolt until the  
washer is flattened, but do not tighten the bolt further. When  
the washer is flattened, this indicates that sufficient torque  
has been applied.

Follow these steps to install the Az/El and reflector bracket  
assembly onto the mast:  
Installing the Az/El and  
reflector bracket  
assembly  
1. Before you install the Az/El and reflector bracket assembly  
onto the mast pipe, use a bubble level to make sure the mast is  
plumb.  
Check the mast at two perpendicular locations, as shown in  
Figure 14.  
Note: The mast must be plumb. The antenna assembly  
cannot be adjusted to correct for a mast that is not plumb.  
Bubble must be centered  
between marks.  
To make sure the mast is  
plumb, check with the level  
in two positions at right  
angles to each other.

3. Optional: If you adjust the antenna elevation now to the  
coarse elevation value, before installing the reflector, it’s  
easier than making this adjustment after the reflector is  
attached. You can make this adjustment now or do it as part  
of the antenna pointing procedure. (See Setting coarse  
elevation on page 61.)  
4. Rotate the Az/El and reflector bracket assembly until the  
reflector side is oriented in the general direction of the  
satellite.  
If necessary, loosen the canister nuts just enough to allow the  
assembly to rotate.  
5. Snug the three canister nuts just enough to prevent the  
assembly from rotating. Do not tighten the nuts at this time.

Follow these instructions to attach the antenna reflector to the  
reflector bracket.  
Attaching the reflector  
Note: This task is easier if someone assists you.  
1. Orient the reflector so the HughesNet logo on the front is  
near the top, as shown in Figure 16.

2. Lift the reflector and align the four mounting holes on the  
back of the reflector with the four mounting holes on the  
reflector bracket. See Figure 17.  
Note: To make it easier to position the reflector and insert  
the screws (steps 2 and 3), you can adjust the elevation of the  
Az/El and reflector bracket assembly beyond the 80° mark on  
the elevation scale so the surface of the reflector bracket that  
attaches to the reflector is nearly horizontal. Then you can lay  
the reflector on the bracket, with the holes in the reflector  
facing the bracket. This method (not illustrated here) is  
especially useful when one person installs the antenna.  
To use this method you must loosen the fine elevation  
adjustment nuts and elevation lockdown bolts identified in  
Figure 48 on page 60. Be sure to tighten the elevation  
lockdown bolts before laying the reflector on the bracket.

(without washers) through the lower holes on the reflector  
bracket and into the lower reflector holes.  
6. Tighten each screw a little; then move on to the next screw.  
7. Use a torque wrench to tighten the screws to 10 ft-lb force  
maximum.  
CAUTION  
To avoid damaging the mounting holes in the back of the  
reflector, do not overtighten the reflector bracket screws.  
Use a torque wrench.

Install the feed rods and feed support tube as explained in the  
following two sections. These instructions apply to both types of  
feed support tubes and feed rods, that is, the tube and feed rods  
for the J-type radio or cradle-type radio.  
Installing the feed  
support tube  
Note: If you are installing an antenna that will use a cradle-type  
radio assembly, make sure the feed support tube and feed rods are  
stamped TG. (Other letters or numbers may appear with TG.) If  
these parts are not stamped TG, they are the wrong parts for the  
cradle-type radio. Contact Installer Support to obtain the correct  
parts.  
Attach the feed rods to the reflector:  
Attaching the feed rods  
1. Attach the feed rods to the rim of the reflector as shown in  
Figure 18.

Follow the instructions in this section only if the installation  
specification or service order states that vertical transmit  
polarization is required. (The vertical shim kit is not used with  
the cradle-type radio.)  
Installing a shim for  
vertical transmit  
polarization  
If vertical transmit polarization is not required, go to Installing  
the radio assembly on page 36.  
The radio assembly is shipped with a horizontal transmit  
polarization shim installed. If vertical transmit polarization is  
required, you must remove the horizontal shim and replace it with  
a vertical transmit polarization shim.  
Note: If you need to change from horizontal to vertical transmit  
polarization on an antenna that has the radio assembly already  
installed on the feed support tube, you will have to remove the  
radio assembly from the feed support tube before you can follow  
the instructions in this section.

5. Install the vertical shim and O-ring in the same location.  
Because of its shape and alignment pins on the  
transmit/receive isolation assembly (TRIA), the vertical shim  
can only be installed in the position shown in Figure 24  
(upper right photo). Note the position of the alignment pins.  
Likewise, the horizontal shim can only be installed in one  
position.  
Because of the shim’s alignment pins, you must rotate the  
TRIA 90° from its horizontal polarization position. You must  
rotate the TRIA before you re-attach the waveguide end so  
you can insert the shim alignment pins into the waveguide  
end plate. See Figures 25 and 26.

not the antenna. This section explains how to calculate and set the  
polarization value for the cradle-type radio assembly.  
Setting polarization for  
the cradle-type radio  
To calculate the polarization setting, refer to the section for the  
type of uplink and downlink that will be used. In these  
instructions, SBC initial value refers to the polarization value  
calculated by the installation software.  
Calculating the radio  
polarization setting  
For a horizontal To calculate the radio polarization setting for a horizontal  
uplink/vertical downlink uplink/vertical downlink:  
1. Multiply the SBC initial value by –1,  
then offset the result by 90° as follows:  
If the SBC initial value is positive, add 90.  
If the SBC initial value is negative, subtract 90.  
Example 1, positive initial value of 41°  
41 × –1 = –41  
Add 90:  
–41 + 90 = 49  
Radio polarization setting = 49°  
Example 2, negative initial value of –41°  
–41 × –1 = 41  
Subtract 90:  
41 – 90 = –49  
Radio polarization setting = –49°.  
2. Make a note of the setting.  
3. Go to Setting the radio polarization on page 48.

Cabling and connections  
This chapter illustrates where the ODU ground, transmit, and  
receive connectors are located; shows how to route the transmit  
and receive cables at the ODU; and explains how to connect the  
transmit and receive cables to the radio assembly. You must  
connect the transmit, receive, and ground cables before you can  
point the antenna (Chapter 7 – Pointing the antenna).  
The chapter includes these sections:  
• Previous cabling work on page 49  
• Routing the cables at the ODU on page 50  
• Ground connection on page 51  
• Connecting the transmit and receive cables on page 52  
Before you can complete the steps explained in this chapter, you  
must route and terminate the transmit and receive cables from the  
IDU to the ODU.  
Previous cabling work  
For a list of approved cables for the IFL between the antenna and  
the remote terminal, see the Field Service Bulletin (FSB), IFL  
Cable, Approved List (with lengths) for DW7x00, DW60xx, and  
DW40xx Domestic Installations (FSB_060316_01A). This FSB  
lists the maximum cable length for each approved cable type, for  
both 1-W and 2-W radios.  
How the cables are run depends on the specific installation site.  
Route and connect the cables according to your training and best  
practices.  
CAUTION  
Coaxial connectors and cable can corrode if exposed to  
moisture. Use only compression type connectors, and  
weatherproof them with dielectric grease and weatherproof  
tape.

This chapter describes a general procedure for pointing the  
antenna. The objectives of antenna pointing are to:  
Antenna pointing  
overview  
• Locate and detect the satellite signal  
• Peak the signal to achieve the greatest possible signal  
strength  
The IDU installation software guides you through a step-by-step  
process for installing the IDU and pointing the antenna. It  
calculates your exact location and the values you use to set  
elevation, polarization, and azimuth. (See also Determining the  
pointing values on page 21.)  
Using the installation  
software  
Use the information in this chapter as a guide for the overall  
pointing process and for instructions on how to make mechanical  
adjustments to the antenna. For specific steps, follow the  
instructions in the IDU installation guide and on the installation  
software screens.  
In general you will alternate between these two activities:  
• Following the software prompts and instructions  
• Adjusting the antenna (elevation, polarization, and azimuth)  
to acquire and then peak the satellite signal. The required  
adjustments are different for each installation location.  
Correct antenna alignment is critical to the operation of the  
system. When the antenna is pointed directly at the satellite, it  
receives a strong signal. If it is not pointed properly, the signal  
may be weak, and errors may result during data transfers.  
Peaking the signal  
(description)  
Antenna pointing is accomplished by first receive pointing the  
antenna and then isolating the transmit signal. Receive pointing  
adjusts the antenna to obtain the best receive signal. Isolating the  
transmit signal fine tunes the antenna alignment for the strongest  
possible signal received by the HN System NOC. Both processes  
are explained later in this chapter.  
To point the antenna, you go through cycles of making small  
adjustments to the antenna until you are satisfied you cannot get a  
stronger satellite signal. When you have achieved the strongest  
possible signal, you have peaked the signal.  
You may achieve the strongest signal strength after just a few  
adjustments, or you may find that several adjustments are needed.  
By obtaining the strongest possible signal you ensure that the  
terminal can operate with peak performance.

One person can point the antenna if an outdoor pointing interface  
(OPI) is used. Otherwise, pointing is usually a two-person task. If  
an OPI is not used, one person aims and adjusts the antenna while  
the other watches the signal strength display on a computer and  
relays the readings to the person at the antenna. A portable  
telephone or walkie-talkie is helpful for this.  
Personnel requirements  
Pointing parameters  
Prior to antenna pointing, you use the installation software to  
enter parameters such as longitude, latitude, and polarization  
angle. Or you can enter the local ZIP code and let the software  
calculate these values.  
The following are required for antenna pointing:  
Prerequisites for  
antenna pointing  
• The antenna must be installed.  
• The IDU must be installed.  
• The transmit and receive cables must be connected to the  
IDU and ODU.  
• The OPI, if used, must be installed. (See Installing the OPI  
on page 58.)  
• The ODU and IDU must be grounded.  
• You must have access to the installation software through the  
IDU.  
The OPI (Hughes P/N 1031393-0002), shown in Figure 45, is an  
optional tool that displays signal strength values.

To prepare for antenna pointing, attach the OPI to the receive  
cable from the LNB, as shown in Figure 46. Note that the OPI  
will not work unless it is enabled on the appropriate screen on the  
installation software. (Check the box labeled Enable OPI  
Display.) For further details, see Outdoor Pointing Interface

To point the antenna you make three adjustments to the position  
of the antenna reflector:  
Adjusting the antenna  
• Elevation – Adjustment up and down  
• Polarization – Rotational adjustment  
• Azimuth – Side-to-side adjustment  
These adjustments are illustrated in Figure 47. The corresponding  
mechanical adjustments on the antenna are shown in Figure 48.  
Note: When recording or using antenna pointing  
values, you must pay attention to whether  
values are positive (+) or negative (-).

The antenna pointing procedure begins with the steps described  
in this section and continues through the end of this chapter.  
Follow the instructions in the order they are presented.  
Setting coarse elevation  
Set the initial (coarse) antenna elevation to the initial elevation  
value given by the installation software, as follows:  
1. Loosen the two fine elevation adjustment nuts indicated in  
Figure 49 so the antenna reflector can move forward and  
backward.  
2. Loosen the two elevation lockdown bolts indicated in  
Figure 49, a little at a time, until you can rotate the antenna  
reflector forward and backward to adjust the elevation.  
Note: Do not tighten the elevation lockdown bolts yet  
because you will be adjusting elevation further, as explained  
in Fine elevation adjustment on page 62.  
3. Set the elevation to the value given by the installation  
software.

The fine elevation adjustment rod (shown in Figure 50) allows  
you to make fine adjustments of the antenna elevation. Where  
subsequent instructions call for fine adjustment of the antenna  
elevation, fine-tune the elevation setting as follows:  
Fine elevation  
adjustment  
1. Make sure the two elevation lockdown bolts are loose enough  
to allow the reflector to move as indicated by the arrow in  
Figure 50.  
2. While watching the signal strength display, adjust the fine  
elevation adjustment nuts (Figure 50) to achieve maximum  
signal strength:  
a. Move the top nut to allow movement, then make  
adjustments with the bottom nut.  
b. Adjust by turning the bottom nut a few turns clockwise and  
counterclockwise, until you peak the signal.

3. When the signal is peaked, tighten the two elevation  
lockdown bolts.  
Receive pointing peaks the receive signal. You must peak the  
signal even if the antenna is locked to it.  
Receive pointing  
You use the installation software to check the signal strength.  
Then you adjust the antenna to peak the signal. The installation  
software shows numerical and graphic indications of signal  
strength. Detailed instructions for these procedures are given in  
the following sections.

Make sure the antenna reflector is set to the initial elevation value  
given by the installation software.  
Initial elevation setting  
Setting polarization  
Polarization refers to rotation of the antenna (as shown in  
Figure 47 on page 59) and is measured in degrees from zero (no  
rotation), positive or negative. Polarization is positive east of the  
satellite longitude and negative west of the satellite longitude.  
For an antenna with a J-type radio, you adjust polarization on the  
antenna only. For an antenna with a cradle-type radio, you set  
polarization on the antenna to 0° and then set polarization on the  
radio. If you are installing the antenna with a cradle-type radio,  
see Setting polarization for the cradle-type radio on page 47.  
(You will also use the instructions in this section.)  
Set the antenna (reflector) polarization as follows:  
1. Loosen the four polarization lockdown nuts just enough so  
you can rotate the antenna reflector. See Figure 51.  
Do not adjust the center nut on each side, as noted in  
Figure 51.  
2. Rotate the antenna to the desired polarization value as  
indicated by the polarization scale (shown in Figure 51).  
J-type radio: Set the antenna polarization to the initial  
polarization value given by the installation software.  
Cradle-type radio: Set the antenna polarization to 0°; then  
see Setting polarization for the cradle-type radio on  
page 47.  
Arrow indicates movement  
during polarization adjustment.  
Do not adjust

or center nut on  
opposite side.

With the elevation and polarization set to the initial values given  
by the installation software, follow these steps to set the antenna  
azimuth to the initial value specified by the installation software  
and then adjust it as necessary:  
Setting azimuth  
1. Use a compass to determine the azimuth bearing specified by  
the installation software.  
2. Prepare to make azimuth adjustments as follows:  
a. Fully loosen the three canister nuts shown in Figure 52.  
b. Tighten the top nut only, just enough so you cannot rotate  
the Az/El assembly around the mast.  
c. Loosen the top nut incrementally until you can rotate the  
Az/El assembly by holding and moving it.  
Canister  
Loosen these three  
nuts to rotate Az/El  
assembly and reflector  
from side to side.  
View from behind reflector  
Figure 52: Azimuth adjustments on the antenna  
3. Stand behind the antenna, grasp the antenna reflector bracket  
(not the reflector), and rotate the antenna assembly about the  
mast until the reflector is pointed in the approximate azimuth  
heading.  
4. Adjust the azimuth to the right about 1⁄8 inch.  
5. Let go of the reflector bracket and count slowly to 5 while  
reading the signal strength value from the OPI or computer.  
You must allow the IDU enough time to track and register the  
signal strength.  
Note: Make small adjustments (not more than 1⁄8 inch of  
azimuth as measured at the mast). Wait 5 sec between  
adjustments to give the IDU enough time to lock onto the  
satellite signal.

6. After acquiring a signal, adjust the azimuth to obtain the  
highest signal quality.  
7. Go to Peaking the signal (procedure) on page 66 and follow  
the instructions there.  
If you cannot detect a signal Follow the steps in this section (steps 1 through 3 and/or steps 1  
through 6) only if you cannot detect a signal.  
If no signal is present:  
1. Repeat steps 3 through 5 in Setting azimuth on page 64.  
(Adjust the reflector to about 1⁄8 inch to the right of the  
approximate azimuth.)  
2. Keep moving the antenna reflector to the right a little at a  
time until you detect a signal.  
3. If there is no signal, sweep back 1 ⁄8 inch at a time to the left  
until you detect a signal.  
If you still cannot detect a signal, there may be an error. If there is  
no signal, perform the following quick checks.  
1. Check the coaxial cable connections at the LNB, IDU, and all  
the connections in between.  
2. Make sure there are no obstructions such as trees blocking the  
signal.  
3. Make sure you recorded and properly set the azimuth,  
elevation, and polarization values.  
4. Verify the azimuth setting by moving 15 ft in front of or  
behind the antenna and taking another compass reading.  
Metal near the compass, such as a car or even a belt buckle,  
can give a false reading.  
5. Point the front of the antenna reflector to the left of the  
estimated bearing.  
6. Go back to step 3 in Setting azimuth on page 64 and try again.  
When you have acquired a signal and adjusted azimuth to obtain  
the highest signal quality, go to Peaking the signal (procedure) on  
page 66 and follow the instructions there.

After the satellite signal is detected, peak the signal as follows:  
Peaking the signal  
(procedure)  
1. Mark the mast with a pencil so you can find the azimuth  
bearing again.  
2. After detecting the satellite, continue turning the antenna  
reflector a small amount in the same direction you were  
turning it when you began receiving the satellite signal.  
Pause for 5 sec after each time you move the reflector.  
3. Turn the reflector in this fashion until the signal strength  
values displayed by the installation software begin to  
decrease.  
4. When the numbers begin to decrease, slowly turn the  
reflector in the opposite direction until you regain the highest  
number that was previously achieved.  
(Achieving this maximum signal strength is called peaking  
the signal.)  
Make a note of the peaked signal strength for reference as  
you complete the pointing process.  
5. When you have peaked the azimuth, snug down the three  
canister nuts as follows:  
a. Alternately and incrementally tighten the lower two nuts  
until the flanges makes contact.  
b. Snug the top nut.  
6. Fine tune the elevation adjustment to verify that signal  
strength remains at the highest level.  
7. If necessary, fine tune the adjustments for azimuth, elevation,  
and polarization to make sure you have achieved and  
maintained the highest possible signal strength.  
8. Erase all marks previously made on the mast.  
9. Lock down (fully tighten) all adjustment nuts.

To prevent signal cross talk, you use a procedure known as  
Automated Cross Polarization (ACP) to isolate the transmit signal  
from the receive signal. ACP test functions are included in the  
installation software.  
Isolating the transmit  
signal  
The ACP software operates in two different modes—manual or  
automatic. Manual mode gives real-time feedback of cross  
polarization isolation measurements while you adjust the antenna.  
Automatic mode takes a snapshot of the cross polarization  
isolation measurement.  
ACP fine pointing consists of testing using both the manual and  
automatic modes and adjusting the antenna by small increments  
(if necessary) until it passes both the manual and automatic ACP  
tests.  
Follow the general instructions below for the ACP tests. Use the  
installation software screens to initiate tests and see the test  
results.  
First run a manual ACP test:  
Manual ACP test  
1. Lock down all antenna adjustment nuts and bolts.  
2. Initiate the manual ACP test by selecting the manual cross  
polarization test type.  
If the manual ACP test passes, stop the test and proceed to  
Automatic ACP test on page 68.  
If the manual ACP test fails, let the test continue and follow these  
steps:  
1. Make small, 1° or less changes in polarization while  
observing the transmitter isolation.  
2. Peak the polarization to the highest possible transmitter  
isolation.  
3. Tighten the polarization lockdown nuts.  
4. Check the signal strength.  
When the manual ACP test passes, stop the test and proceed to  
Automatic ACP test.

Verify that the signal is still peaked by initiating an automatic  
ACP test. To initiate this test, select the automatic cross  
polarization test type. If the antenna passes the automatic ACP  
test and maintains signal strength within 3 points on the signal  
strength scale, it is pointed and ready to be registered.  
Automatic ACP test  
If the antenna fails the automatic ACP test, follow these steps:  
1. Initiate a manual ACP test.  
2. When the test starts, make small, 1° or less changes in  
polarization while observing the transmitter isolation.  
3. Peak the polarization to the highest possible transmitter  
isolation.  
4. Tighten the polarization lockdown nuts.  
5. If the antenna passes the manual test, stop the manual test and  
run the automatic ACP test again.  
6. Check the signal strength.  
If the antenna passes the automatic ACP test and maintains signal  
strength within 3 points on the signal strength scale, it is pointed  
and ready to be registered.  
If the antenna passes the automatic ACP test, but the signal  
strength drops more than 3 points after the test, you must repeat  
the fine adjustments for azimuth and elevation:  
1. Repeat the fine adjustments for both azimuth and elevation to  
maximize the signal strength.  
2. Repeat the automatic ACP test.  
3. Check the signal strength.  
If the antenna passes the automatic ACP test and maintains signal  
strength within 3 points on the signal strength scale, it is pointed  
and ready to be registered.  
If the antenna still does not meet both criteria, repeat very small  
polarization, azimuth, and elevation adjustments and ACP tests as  
many times as necessary until you have peaked the signal and the  
antenna passes the automatic ACP test and signal strength is  
maintained within 3 points.  
Important: When you are finished pointing the antenna, lock  
down all pointing adjustments. All adjustment points are shown  
in Figure 48 on page 60.

Complete the following steps before leaving the installation site.  
Remove the OPI so you can re-use it for subsequent installations:  
Final steps  
Remove the OPI  
1. Disconnect the OPI and block, if used.  
2. Reconnect the receive cable to the radio.  
Make sure the required safety labels and/or signs are present:  
Check for safety labels and  
signs  
• Make sure a Radiation Hazard Caution label is present,  
legible, and visible on the feed arm and on the back of the  
antenna reflector.  
• If the antenna is enclosed by a fence, make sure a Radiation  
Hazard Caution sign is present, legible, and visible on the  
entrance gate.  
• If the antenna is installed on a roof with a permanently  
mounted access ladder, make sure a Radiation Hazard  
Caution sign is present, legible, and visible on or near the  
ladder.  
The antenna is now installed and pointed, ready for operation.  
Subsequent steps  
To commission the IDU (remote terminal), refer to the IDU  
installation manual.
