ACS-101
Instruction Sheet
General Description
AMPLIFIED BROADBAND UHF
COMBINER-SPLITTER
PN 803984
The ACS-101 (Antenna Combiner Splitter 10 to 1) is an
amplified and filtered broadband splitter-combiner. It
allows up to 10 base stations to use only one transmit
and one receive antenna.
The antenna splitter section has broadband input fil-
tering and amplification to maintain signal levels
through the splitters. High output isolation between
ports is also achieved.
The antenna combiner section contains innovative
hybrid coupling, amplifying and matching technol-
ogy to combine 10 transmitters to 1 output with
very low intermod distortion.
The industrial strength power supply of the ACS-101
supplies voltage and current to two outputs on the prod-
uct. Each output can supply up to 5 Amps at 12 VDC.

Antenna Requirements
The ACS-101 may be used with a variety of anten-
nas. For best results, use a pair of ALP-450 direc-
tional log periodic antennas (See Figure 5) or, the
ALP-600 Bi-directional log periodic antenna (See
Figure 6).
When using 1/2 wave antennas, we recommend us-
ing the higher frequency model when the receivers
operate in more than one band. If the receivers are
more than one band apart, such as yellow and
white, we strongly recommend using the ALP-450,
or ALP-600 depending on the application.
Good results may also be obtained with 1/2 wave
antennas (See Figure 7). All antennas are sold sepa-
rately.
Place the ACS-101 with antennas in a location that
is in direct view of the beltpacks for best results.

Antenna Placement
for Optimum Range and Rack Mounting
Rack Mounting
Rack mount brackets are supplied with the
ACS-101. To attach the brackets, proceed as fol-
lows:
·
For maximum range and when rack mounting, the
antennas must be remotely located.
Align the rack mount bracket with the holes on
the side of the unit. See Figure 8.
·
The ALP-450 and ALP-600 antennas come com-
plete with a variety of mounting hardware and 10
feet (3 meters) of low loss coaxial cable. A combi-
nation mounting bracket with 10 feet of coaxial ca-
ble is available for 1/2 wave antennas (Model No.
AB-2).
Install flat head machine screws in two holes.
·
Tighten securely. Repeat on the other side of the
unit. For best alignment, perform the above
steps while the unit and rack brackets are set-
ting on a flat surface.
Antennas should be placed in a location with a clear
“signal path” to the beltpacks. This “path” should
be as short and free of obstructions as possible. Ob-
structions, such as walls ceilings, and metal objects,
will reduce range and performance.
Insert the unit into a 19" rack enclosure and in-
sert four screws (not supplied) in each corner of
the rack mount brackets and secure.
·
Coax Cable
For best results, it is recommended that cable losses
be kept under 4 dB. (Every 3 dB of signal loss results
in a system operating distance reduction of 25%.
See the accessories section of this manual for spe-
cial low loss cable assemblies.
