cb tranceiver
The Citizens Band lies between the shortwave
broadcast and 10-meter Amateur radio bands, and
was established by law in 1949. The Class D two-
way communications service was opened in 1959.
(CB also includes a Class A citizens band
and Class C remote control frequencies.)
Federal Communications FCC Regulations
FCC regulations permit only “transmissions”
(one party to another) rather than “broadcasts”
(to a wide audience). Thus, advertising is
not allowed on CB Channels because that is
“broadcasting.”
FCC Warnings
All transmitter adjustments other than those
supplied by the manufacturer as front panel
operating controls, must be made by, or under
the supervision of, the holder of an FCC-issued
general Radio-Telephone Operator’s License.
Replacement or substitution of transistors,
regular diodes or other parts of a unique nature,
with parts other than those recommended by
Cobra, may cause violation of the technical
regulations of Part 95 of the FCC Rules, or
violation of Type Acceptance requirements of
Part 2 of the Rules.

Mounting and
Connection
Mounting and Connection
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.
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.
Note
The transceiver is held in the
universal mounting bracket
by two thumbscrews which
allow for adjustment at a
convenient angle.
The bracket includes two
self-tapping screws and star
washers. The mounting
must be mechanically strong,
conveniently located.
continued
Drill the holes and secure the bracket.

In a negative grounded vehicle, connect the
red lead of the DC power cord to an accessory
12 volt fuse.
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.

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
For best performance, we
recommend the radio be
connected directly to the
battery.
Note
Before installing the CB
radio, visually check the
vehicle’s battery connection
to determine which terminal is
positive or negative.
A negatively grounded vehicle
has its negative lead grounded
to the chassis.
Note
Connecting to an accessory
fuse prevents the unit from
being left on accidentally, and
also permits operating the unit
without running the engine.

Ignition Noise Interference
Antennas
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 NW 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.
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
maximum power output. Cobra® loaded type
antenna models are highly recommended for
most installations. Consult your Cobra® dealer for
further details, or visit or website:
www.cobra.com.
Marine Installation
The transceiver will not operate at maximum
efficiency in a boat without a ground plane,
(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.
CB Antenna
7
Note
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.
Note
Because many newer trucks
feature fiberglass door skins,
the outside mirror must be
grounded to the chassis via
ground strap, if the antenna is
mounted on the mirror bracket.
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.
6
1
A standard antenna connector is provided
on the transceiver for easy connection.

Calibrate for SWR (Standing Wave Ratio)
SWR calibration is required to accurately measure
SWR on the built in meter. We suggest performing
this calibration procedure before placing the meter
