[TowerTalk] Hy-Gain HG-50MT2 rotor mounting

[Bob Newton W5RN]

Rick,

I don't know about the HG-50MT2 but I have the HG-35MT2 (the 35 foot 
version) and it is rated for 9.5 square feet in 50 mph winds side 
supported at 8 feet. I have mine supported at about 17 feet which is the 
eve of the second story of the house. As for the rotator I use a Ham III 
and yes, it mounts to the top of the tower per Hy-Gain instructions. I 
have had no problems with it in the 25 years that I have had it up with 
a Cushcraft ATB-34 about 3 feet above the tower top. Admittedly, I do 
crank it down if the wind starts to pick up so it hasn't had any real 
tests in that area. One other thing, the Ham III will handle 7.5 square 
feet mounted in this fashion. I think the wind speed is also 50 mph.
