Installation
Note
Connecting to an accessory fuse
prevents the unit from being left
on accidentally, and also
permits operating the unit
without running the engine.

Plug power cable into back of unit marked
“Power”. Be sure to observe polarity markings.
Mount the microphone
bracket on either side of
the unit (driver’s left)
using two screws
supplied. Bracket should
be placed under the dash
so microphone is readily
accessible.
Note
In positive ground vehicles the
red wire goes to the chassis and
the black wire is connected to
the ignition switch.

In a negative grounded vehicle, connect the
red lead of the DC power cord to an accessory
12 volt fuse.
Note
Before installing the CB radio,
visually check the vehicle’s
battery connection to
determine which terminal,
positive or negative, is
grounded (positive is the
larger of the two) to the
engine block (or chassis). A
negatively grounded vehicle
has its negative lead
Connect the black lead to the negative side of
the vehicle.This is usually the chassis. Any
convenient location with a good electrical
contact (remove paint) may be used.

Antennas
CB Antenna
Note
Ignition Noise Interference
Use of a mobile receiver at low signal levels is
CB Antenna
normally limited by the presence of electrical
noise.The primary source of noise in automobiles
is from the alternator and ignition system.
Typically, when signal level is adequate, the
background noise does not present a serious
problem. Also, when extremely low level signals
are being received, the transceiver may be
operated with the vehicle’s engine turned off.The
unit requires very little current and therefore will
not significantly discharge the vehicle’s battery.
Since the maximum allowable power output of
the transmitter is limited by the FCC, the antenna
is critical in affecting transmission distance. Only
a properly matched antenna system will allow
maximum power output. Cobra loaded type
antenna models are highly recommended for
most installations. Consult your Cobra dealer for
further details, or call 773.889.3087 and speak to
a Cobra representative.
For optimum performance in
passenger cars the ideal
antenna location is on the
center of the roof. Second
choice is on the
center of the trunk.
Even though the Cobra 29 LTD CHR has an
automatic noise limiter, in some installations
ignition interference may be high enough to
make good communications impossible. Many
possibilities exist and variations between vehicles
require different solutions. Consult your COBRA
dealer or a 2-way radio technician for help in
locating the source of a severe noise.
Note
Because many newer trucks
feature fiberglass door skins, the
outside mirror must be
grounded to the chassis via a
ground strap when antenna is
mounted on the mirror bracket.
1
A standard antenna connector is provided
on the transceiver for easy connection.
Note
3-way Combination
Antennas are also available
which allow operation of all
three bands (AM-FM & CB),
using a single antenna.
However, this type of antenna
usually results in less than
normal transmit and receive
range when compared to a
standard-type“Single Band”CB
antenna. Call 773-889-3087 for
further information.
Marine Installation
The transceiver will not operate at maximum
efficiency in a boat without a ground plate,
(unless it has a steel hull). Before attempting
installation , consult your dealer for information
regarding an adequate grounding system and
prevention of electrolysis between fittings in the
hull and water.

Calibrate for SWR (Standing Wave Ratio)
Calibrate For
SWR (Standing
Wave Ratio)
SWR calibration is done to properly adjust the
length of the antenna and to monitor the quality
of the coaxial cable and all RF connections.
This calibration is critical in order to achieve
optimum performance.
Note
Calibration must be made in an
open area (never in a garage).
Vehicle doors must be closed.
No one should be standing near
the antenna. (See your antenna
directions for more complete
information).
Note

will illuminate when TX if
SWR is high.
