1. [TowerTalk] US Towers and wind Loading Capacity (score: 1)
Author: K4IA@aol.com (K4IA@aol.com)
Date: Fri Jun 20 10:31:31 2003
I am confused. The rotor and mast are a 25 pound wind load? That seems like a lot -- it is more than a big antenna. How can that be? I would have thought the mast and rotor would be minimal wind load

I had one and also a Cushcraftt R7000. All verticals are subject to vertically polarized man made noise. There is nothing magic about the Titan to make it immune. Overall it was a decent atnenna on 4

OK - let's start a brawl. Yes, I have read the reviews on eHam and know the obvious stuff like the Mosley is a rotatable dipole on 12 and 17 where the C3SS claims gain. FTB better on Mosley. Size and

Be very very careful. If that thing gets away, you are dragging 300 feet of wire across the landscape -- including power lines. Even if it goes straight up at first, it will come down eventually and

I like your idea of the light duty link between the antenna and the balloon. That is better than a slip knot. But it is not redundant. In other words, if your wire and static line both came undone at

I don't know how the Trig would work but in the Boy Scouts we learned to measure the length of the shadow. Compare that to the length of a shadow from an object of known height and figure the ratio.
