Review on K40 K40MM 3-Way Mirror Mount Double Groove CB Antenna - Chrome Plated, 60mm by Rubeen Black

Recommended when using something with more wind load than, say, a gamstick or short fiberglass CB whip. Built like a tank, well made and reasonably priced. I attached this mount to an M16 bolt that threaded into my Crosstrek's front tow hook hole and supported a lightweight antenna with a hand screwdriver. The mount doesn't flex like the standard 3/8 bolt mount it replaced and I'm no longer afraid to ride without removing my RF antenna.
