Connecting Your CB Radio
Installing the Antenna
To install the supplied antenna, align the
two slots on the antenna connector with
the tabs on the BNC connector of the
CB radio. Push the antenna connector
to the CB radio and rotate the antenna
connector clockwise until it locks into
place.
Installing an Optional Antenna
The CB’s BNC connector allows you
to use a variety of optional antennas,
including external mobile antennas and
outdoor base station antennas.
Always use the 50-ohm, RG-58, or RG-8 coaxial cable to connect
an outdoor antenna. If the antenna is over 50 feet from the CB
radio, use the RG-8 low-loss dielectric coaxial cable.
Safety Precaution:
If an outside antenna is installed, be sure the antenna system is
grounded so as to provide protection against voltage surges and
built-up static charges. When installing the antenna, be careful not
to touch overhead power lines as contact with them might be fatal.
Connecting an External Speaker or Microphone
Connect an external speaker (not
included) to the SPK jack of your
CB radio. This mutes the CB’s
internal speaker.
Connect an external microphone
(not included) to the MIC jack of
your CB radio. This disables the
CB’s internal microphone.
