I doubt that Rohn's safety factor is anywhere near 3:1 ... EIA 222-F specifies safety factors between 1.5 and 2 to 1 in the steel depending on several things including length to diameter ratios of t

Two reasons ... 1) the Cushcraft 2-el 40 has significantly less windload than the TH7 and thus stacking it on the top will impose less stress on the mast. 2) the added height is more important on 40
