[TowerTalk] US Towers and wind Loading Capacity

[Michael Hatzakis, Jr]

hmmm, my PE calculations at 80mph give a max of around 6sq ft of antenna.  Happy to show their calcs for MA-550
 
But to be sure, I'm putting in an electric winch to bring it down to "half mast" whenever I don't use it.

True. King County here is WA has an 85 MPH rating. The last MA tower I 
installed here was PE rated at a 25 pound load at that windspeed. Your rotator 
and mast will fit but no antennas.
