Steve is most likely correct, but the allowable loads specified by ROHN are
the maximum allowed by the building codes for the wind speed specified. The
building codes specify minimum design strength and wind speed for the
protection of life. This means it prudent to use a higher than minimum wind
speed if you care about survival of your antenna tower.
Second, the antenna is connected by a wire that will keep the antenna
"catching wind" like a sail after it fails. This is why building codes do not
allow the concept of break away antenas similar to signs.
