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. -- Bob D. ND9B |

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: http://www.teeveesupply.com/product_...nting_hardware ..htm 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. 73, "Sal" (KD6VKW |
