Lester's StikTite Antenna Positioning Clamp is designed to fit a 1" Tracking and/or Training Collar with a standard/original antenna. 
The clamp's purpose is to position the antenna by sliding to the location on the collar, that is preferred by the houndsman. The antenna snaps into the clamp, and can be tightened down, onto the antenna, with a 2mm hex wrench to limit antenna snap-outs, and to keep the antenna from slipping to an undesirable position on the collar.
Lester's StikTite is made in the U.S.A., and has been field tested, for it's durability and performance. Say goodbye to those annoying zip ties, that slow you down getting into the field.   Lester's StikTite stays, where you put it and keeps the antenna, where you want it.
