INSTALLING AN

ANTENNA

Caution: To prevent damage to your CB, you must connect an antenna to it before you operate it.

Note: If you are using this CB as a base station, see “Using the CB as a Base Station” on Page 9.

Selecting an Antenna

When deciding on an antenna and where to locate it, consider these points:

•The location of the antenna should be as high as possible.

•The antenna and antenna cable should be as far as possible from sources of electrical noise (igni- tion systems, gauges, and so on).

Your local RadioShack store sells a variety of CB antennas for both mobile and base-station use. Choose the one that best meets your needs.

Connecting an Antenna

Once you choose an antenna, follow its mounting instructions. Route the antenna’s cable to the CB, then screw the cable to the ANTENNA jack on the back of the CB.
