It makes no difference if you have seven sections or thirty sections of
Rohn 45, none of that weight is on the rotator. If you are using mast and
a bearing there is no weight on the rotator. Even if you did not have a
bearing the mast and antenna weight may be only 150 pounds. The only
number that you should be concerned with is the Sq Ft rating of the
rotator and the antenna load Sq Ft. BTW I would not recommend using
galvanized pipe with this antenna. Pipe is not designed for structural
applications and could bend or fracture.

I have a HyGain Tailtwister rotor mounted inside seven sections of Rohn
45. I
plan on placing a 10 foot mast into the rotor (2" O.D.
galvanized steel pipe), through a heavy duty thrust bearing, and on the
mast, a
HyGain TH-11 (not exactly a featherweight itself).
My question is: How much weight will the Tailtwister rotor handle?
Is potentially this too much weight? I have been told that the HyGain rotors
will handle up to 1000 lbs of weight. While I'm not
close tot hat weight, this is a heavy amount. Any help would be appreciated.
Thanks in advance,
Dave, W8QW
