Connect an Antenna
There are many different types of CB antennas for mobile
CBs. Each type has its own benefits, so choose the one that
best meets your needs. Your local RadioShack sells a wide
variety of antennas. When choosing an antenna, keep in mind

•
as high as possible in the vehicle.
•
as far as possible from sources of electrical noise.
•
vertically.
1. Follow the antenna’s mounting instructions.
2. Route the antenna cable to the CB radio and connect it to
the ANT. jack.
