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 self­tapping screws and star wash­ers. The mounting must be
mechanically strong, conve­niently located.

continued

Drill the holes and secure the bracket.

Connect the antenna cable plug to the recep­tacle marked “ANT” on the back of the unit.

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

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

Note

In positive ground vehicles the
red wire goes to the chassis and
the black wire is connected to
the ignition switch.

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.

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.

4

5

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.

securely.

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 WX NW BT 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. For models with Weather Feature (WX), a

Dual Band (Center Load/Base Load) antenna is
recommended. Consult your Cobra dealer for fur-

ther details,or call 773.889.3087 and speak to a
Cobra representative.

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.

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 a 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. Call 773­889-3087 for further informa­tion.

A standard antenna connector is provided
on the transceiver for easy connection.

The CB/PA button should be in the
CB position.

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).

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

For a list of weather frequencies
see specification in the
Frequency Ranges section on
page 34.

If you wish to receive a listing of
NOAA ‘Weather Radio
Transmitter locations, contact
your nearest National Weather.

Service Office, or write to:
National Weather Service
(Attn: W/OM11) NOAA
Silver Springs, MD 20910.

For ideal weather reception use
a dual band antenna (center
load/baseload).

What You Should Know About Weather

If threatening weather is nearby, the National
Weather Service may broadcast a 10 second alert
tone. This tone will be heard through the CB, even
if the CB/WX Switch is in the CB mode or the unit
is turned off.

This enables you to monitor CB frequencies and
still be warned by the National Weather Service
Emergency Alert. When you hear the alert, place
the CB/WX switch in the WX position. You will
then be able to hear the Weather Warning
Broadcast.

You can completely disable the Emergency
Weather Alert feature by turning the Weather
Channel Selector to the position.

Your 29 WX NW BT has a special auto squelch cir­cuit for weather transmission which disables your
squelch control.

If you are using the CB mode, remember to
change the CB/WX Switch from CB to WX every so
often to make sure you are continually tuned to
the clearest/closest weather band channel in case
an alert is broadcast.

What is Weather Radio

NOAA Weather Radio (NWR) is a service of the
National Oceanic and Atmospheric Administration
(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 7 National
Weather Channels provide full coverage to keep
you informed of weather conditions, 24 hours a
day, 7 days a week.

The Citizens Band lies between the shor twave
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.)

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.

You should read and understand Part 95 (included
with this unit) of the FCC Rules and Regulations,
before operating your Cobra radio, even though
the FCC no longer requires you to obtain an oper­ator’s license.
