Also the snow load tends to break guys and fold towers as the snow shifts down the hills. thanks Yahoo!

Darin, get two ten foot sections of used tower sections at a swap. Made for your project. Strong, light and you can guy them for extra safety. They are made to bring the wind load down to the base.

My point was the stuff is rather soft and bends well, not quite the ultimate desire for a mast. Daron J.

I wouldn't want to mess with someone who goes around bending 2" water pipe all day long. Best answer would be to ask a mechanical engineer who is also a ham. Round these parts the mast of choice is oil well drilling rod or also called sucker rod. I have never used it but hear others who have. Myself, I use 1 1/2" Rigid Conduit, but not over 10 ft length, and after cantilever, only abt 6 ft is exposed to lateral forces. Wonder if a Rohn (rip) catalogue might have some specifications for such? Regards, Steve But I might be wrong. Yahoo!
