Connecting an external antenna
You will need to purchase an antenna to operate the radio. However, Your
Uniden dealer can help you select the antenna that is best for your needs.
Consult the specications in the back of this manual for detailed transmitter
and antenna information.
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 specications 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.
