Location
Location
Plan location of transceiver and microphone
bracket before starting the installation.
Select a location that is convenient for operation,
yet does not interfere with the driver or passenger.
The transceiver is usually mounted to the underside of the dash with the microphone bracket
beside it.

Connection
Mounting and Connection
1
Note
The transceiver is held in the
universal mounting bracket by
two thumbscrews which allow
for adjustment at a convenient
angle.
Hold the radio with the mounting bracket in
the exact desired location. If there is no interference, remove the bracket and use it as a
template to mark the location for the mounting screws.
3
Connect the antenna cable plug to the receptacle marked “ANT” on the back of the unit.
The bracket includes two selftapping screws and star washers. The mounting must be
mechanically strong, conveniently located.
2
Drill the holes and secure the bracket.

Installation
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
grounded to the chassis.
Note
6
Plug power cable into back of unit marked
“Power”. Be sure to observe polarity markings.
7
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.
Connecting to an accessory fuse
prevents the unit from being left
on accidentally, and also permits operating the unit without
running the engine.
4
Note
In positive ground vehicles the
red wire goes to the chassis and
the black wire is connected to
the ignition switch.
5
Note
When connected to an accessory fuse, unit will self test
the emergency weather alert
automatically when ignition
is turned on. Turns itself on & off.
Note
If microphone is not
connected, audio will not
be heard at speaker.
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.

4
29LX_CHR_MANL.indd 4-5
In a negative grounded vehicle, connect the
red lead of the DC power cord to an accessory
12 volt fuse.
Attach the 4-pin microphone cable to
receptacle on front of unit and install unit
in bracket securely.

Antennas
Ignition Noise Interference
CB Antenna
CB Antenna
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 maxiNote
mum power output. Cobra loaded type antenna
For optimum performance in
models are highly recommended for most instalpassenger cars the ideal anten- lations. For models with Weather Feature (WX),
na location is on the center of
a Dual Band (Center Load/Base Load) antenna
the roof. Second choice is on the is recommended. Consult your Cobra dealer for
center of the trunk.
further details, or call 773.889.3087 and speak to a
Cobra representative.
Note
Because many newer trucks
feature fiberglass door skins,
the outside mirror must be
grounded to the chassis via a
ground strap, if the antenna is
mounted on the mirror bracket.
Use of a mobile receiver at low signal levels is
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.
Even though the Cobra 29 LX CHR LE 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
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 773889-3087 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.

29LX_CHR_MANL.indd 6-7
A standard antenna connector is provided
on the transceiver for easy connection.

What is Weather Radio?
NOAA Weather Radio (NWR) is a
service of the National Oceanic

(NOAA), of the U.S. Department
of Commerce. 380 NWR stations are in operation by the
U.S. Government in addition to
several NWR stations that are
maintained by private interest
groups. The capability is to supplement warnings by sirens and
by commercial radio and television. The 10 National Weather
Channels provide full coverage to keep you informed of
weather conditions, 24 hours a
day, 7 days a week.
