[TowerTalk] Joining sections of aluminum mast

[larryj at teleport.com]

That tower load caught my eye, too. I have an HDBX tower, and I was only able to get the City's tower permit by staying within the Rohn published load limits. So I went with a 2-element tri-band quad antenna, which only had a boom length of 8 feet.

At a previous QTH, I had a Mosley TA-33 tri-band yagi. But I couldn't put it on this BX tower, since the boom length (I think it was 16 feet) exceeded the 10-foot allowable boom length in the tower ratings' specifications.

When I read this thread about a SteppIR was being put up on a BX tower, that caught my eye, immediately. I've seen two - folded-over/destroyed BX towers in this area, with antenna loads that exceeded Rohn's specs. Fortunately, neither of them were mine.

BX tower is rated for a maximum of 6 square feet of wind load, with a maximum boom length of 10 feet. The Stepp IR 3 element exceeds that on both counts.
A mast running the length of the tower also adds to the wind load.

I agree with Bob. Having the rotator at the base would be great but if you
own a SteppIR (which it´s a fabulous antenna) a new whole installations
including a fold over base would be almost a must. 73s!
