Environment: 50 foot AGL Rohn 45G flat top bracketed @ 23 feet, T2X
TailTwister on Rohn rotor shelf, Rohn 2 inch bearing, Hy-Gain TH-7 1 – 2
feet above bearing, with boom support (3 feet above boom).
I’ve had a ten foot section of 2 inch schedule 40 galvanized pipe in a similar
(tapered top – exception) environment for close to thirty years. I’m now
getting ready to replace the existing tower with new, cables, rotor, antenna,
etc. Maximum intended life of the new installation: No more than 15 years
Thus far I have not found a source with specifications of 2 inch mast tube and
have been looking at galvanized pipe again, either schedule 40 or schedule 80.
I took a S.W.A.G. the last time and was fresh from working at a steam power
plant where we worked with pipes daily. That knowledge is gone; anyone have any
suggestions or recommendations for a rotor mast carrying 75 pounds, 12 sq feet,
and 240 pound wind load at 80 MPH? tube or pipe, sched 40 or sched 80, where to
buy?
