The antenna masts are threaded on mounts at the rear of the motorcycle. Unscrew the antennas if they must be removed. When installing, hand-tighten only.
The radio and CB antennas are different. For vehicles with a CB, install the CB antenna (marked with the letters "CB" at the base of the mast) on the right side of the motorcycle. Installing the incorrect antenna for the radio or CB results in degraded reception.
