[TowerTalk] US Tower "MA" Series Tubular Towers

[Steven H. Sawyers n0yvy]

They are rated at 50 mph for their wind loads. 

I have spent a lot of time trying to help local hams engineer them in an 
80 MPH wind district. We finally had to house bracket them and restrict
elevation to 40 feet to get them to meet EIA-222 rev F. This with the 
standard three element tri-bander and a 10 element 2 meter beam i.e. 
not much of an antenna load.

I personally do not recommend their use. I wish they would redesign
them for realistic wind districts and antennas.
