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.
CAUTION: Never operate your radio with no
antenna or with a damaged antenna cable.
This can damage the radio.
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.
Once your antenna is installed, tune it using a
Standing-Wave Ratio (SWR) meter (not included):
set it to channel 20 and adjust the antenna until
the SWR is as close as 1:1 as possible.
CAUTION: Make sure the SWR is less than 2:1
before using the radio. An SWR higher than
2:1 can damage the radio.
Safety Notice
The antenna used for this radio must be properly
installed and maintained and must provide a
separation distance of at least 16.9 inches (43 cm)
from all persons and must not be collocated or
operated in conjunction with any other antenna or
transmitter. Never transmit if any person is closer
than the specified distance to the antenna.
