Mobile Antenna
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. 
Connecting the Power Cords 
Uniden recommends connecting the power lead to the Ignition Switch 
Accessory Terminal. This way, the transceiver is automatically turned off 
when the ignition switch is turned off. 
As an alternative, the power cord may be connected to an available 
terminal on the fuse block or to a point in the wiring harness. However, 
caution must be taken to prevent a short circuit. If in doubt, contact your 
vehicle dealer for information. 
Ground Information 
This transceiver may be installed and used in any 12-volt DC negative ground 
system vehicle. 
negative ground system 
With a negative ground system, the negative (-) battery terminal is 
usually connected to the vehicle motor block.  
Connect the red DC power cord from the 
transceiver to the positive (+) battery terminal
