The K40 SF CB antenna is available in black or white and in lengths of 2', 3' & 4'. SWR tuning is a breeze with the SF's tunable tip design. This K40 CB antenna can be mounted in any 3/8" x 24 threaded stud mount such as the Firestik K4A.

The K40 SF CB antenna has a tuneable tip for easy SWR tuning. If the SWR is greater on Channel 40 than on Channel 1, then you have an electrically long antenna and need to make it smaller by screwing in the tip or removing it (if necessary). If the SWR is greater on Channel 1 than on Channel 40, then you have a electrically short antenna and need to unscrew the tip (to make it longer) or you can add a spring or quick disconnect to make it longer.
