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.

transceiver to the positive (+) battery terminal
