Connecting an external antenna
WARNING! The antenna used for this radio must be installed at least
8 inches (20 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 will need to purchase an antenna to operate the radio. There are
two basic types of mobile CB antennas--full-length whips and loaded
whips--with a wide variety of mounts to suit different vehicle locations.
► Choose an antenna that matches the specifications of this radio.
► Follow the manufacturer’s installation instructions carefully.
► Tune your antenna using a Standing-Wave Ratio (SWR) meter: set
the radio 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 transmitter.
Your Uniden dealer can help you select the antenna that is best for your
needs. Consult the specifications in the back of this manual for detailed
transmitter and antenna information.
