Do you need a CB antenna that can take a beating? Are you likely to drive in an area with tree branches, low obstructions, or garage doors? Consider going flexible. The Firestik Firefly series is designed specifically for these types of environments.
Aside from the hi-performance loading coil that maximizes the transmit/receive functions of your CB, these top-loaded antennas will also receive the NOAA emergency weather alert and national weather broadcasts for radios with those features.
