With its 180 whip action capability, the principle advantage of the K40 Superflex Whip is its ability to withstand extreme shock obstructions
without breakage. In two, three, four, and 41/2 foot lengths.

Adjustable tuning whip 
The exclusive K40 tuning whip simplifies matching the antenna to your system. To fine tune the VSWR with a VSWR meter, move the whip up or down in 1/8" increments.

Determining which way to move whip
If Channel 1 VSWR is higher than Channel 40 VSWR - the whip should be moved upward.

If Channel 1 VSWR is lower then Channel 40 VSWR - the whip should be moved downward.
