INSTALLATION

MOBILE INSTALLATION

Plan the location of the transceiver and microphone bracket before 

beginning installation.

1.  Select a location that is convenient for operating the radio, but 

does not interfere with the driver or passenger.

2.  Install bracket with self-tapping screws provided.

3.  Connect power cords (see page 9).

4.  Attach the microphone bracket to the side of the radio.

5.  Attach radio to bracket.

Mobile Antenna

WARNING! The antenna used for this radio must be installed at least 16.92 

inches (43 cm) away from all persons. The antenna must not be collocated 

or used with any other antenna or transmitter.  

 

CAUTION: Never operate your radio with no antenna or with a damaged 
antenna cable. This can damage the radio.

You must purchase an antenna to operate this radio. Because the 

maximum power output of the transmitter is limited by the FCC, the 

quality of your antenna is very important. To achieve the maximum 

transmission distance, Uniden strongly recommends that you install only 

a high quality antenna. You have just purchased a superior transceiver - 

don’t diminish its performance by installing an inferior antenna. 

Only a properly matched antenna system will allow maximum power 

transfer from the 50 ohm transmission line to the radiating element. 

Your Uniden dealer is qualified to help you select the proper antenna for 

your requirements. A whip style antenna may be used for automobile 

installation. 

A short ‘loaded’ whip antenna is easier to install on an automobile, but its 

efficiency is less than that of a full quarter-wave whip antenna.
