My beams twist more than Chubby Checker
 

Every antenna I ever bolted to a mast twisted. Tri-banders, 2M, TV antennas
always land up pointing in the wrong direction. I've had antennas actually
rotate, winding the coax around the mast till it pulls off. Does anyone have
a tip for keeping antennas fixed to the mast? No matter how tight the U
bolts are, the wind aways seems to win in the end.

For several antennas I am using an add-on to the u-bolt. See it (or
similar) used with a u-bolt as item 8718 on this page:

The toothed edges seem to dig into the mast section enough to keep it from
turning. If you need to be really secure, I suppose you could pin it
through the mast. The pinning idea also works with the antenna alone, but
I'd avoid putting another hole in the boom. Also, a pin alone allows some
angular movement, which you are setting out to prevent.

You may need a longer u-bolt than came with the antenna.

SRI for the double post, I had a server hiccup.
