[Elecraft] The Whip Wedge: An anti-rotation device for a whip on a right-angle BNC adapter

[Wayne Burdick]

If you use a whip with a right-angle BNC, it's free to rotate, and can flop over. Mathematically speaking, this is most likely to happen just as a breeze comes up and/or you were about to crack that Bouvet Island pileup using 1 watt.

The simplest home-made anti-rotation device for use with your KX3 or KX2 is a piece of medium-soft rubber hose or tubing about 3/4" long. Simply wedge this bit of tubing between the right side panel and the whip's BNC connector. 

If the tubing is too long, it will put an unnecessary amount of force on the BNC connectors. Adjust as required so that you have just enough friction to prevent rotation.

I proposed the name "Whip Wedge" in hopes that someone will now commercialize it. The rest is left as an exercise for the reader :)

Ideally the Wedge would have a more interesting and functional shape than a simple cylinder. It might be a rectangular block with a semicircular cutout matching the side of the BNC connector. (Molding required.)
