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 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.

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.

Attach the 6-pin microphone cable to recepta­cle on front of unit and Install unit in bracket 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.

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
The reading will be slightly high­er on Channels 1 and 40 com­pared to Channel 20.
Push and hold mic button.
Switch to the CAL position.

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.

Rotate the On/Off Volume knob clockwise the green RT/TX LED will be illuminated.
Repeat the same steps two through five on Channel 1 and 40. This will check SWR for all channels.
The S/RF-SWR-CAL switch must be in the S/RF position to read the meter.
