One more point for wind-loading which would not affect you but possibly others on the reflector. I belive the figures given assume sea level. If you are at a high altitude, you can derate the convers

Ford, I would get a written quote for replacement Rohn 25G from a dealer, including tax, license, and freight. :-) Then a written quote to have someone install it for you. This is equivalent replacem

With great, great care. Those pressures probably represent the peak pressure on a flat surface and the tower was old enough that capacities are based upon EIA RS-222-C (or earlier); "Zone A" under RS

Sea level at a nominal temperature and relative humidity. The density of the air is down by 15% (3% per 1000'), but the dynamic pressure goes like rho*v^2 A wind speed of 92 mph @ 5000' is the pressu
