[PVRCNC] Rohn 25G - how many beams?

[Jim K4QPL]

Brad,

I'm not an engineer or an authority, but I sure wouldn't hang that much
aluminum on Rohn 25. Even well guyed that's a heck of a lot both in terms of
vertical load, icing and in a strong wind. Somebody also has to climb that
thing. Safety First!  Most of the people I know go to 45 or 55 once things
move beyond a tribander and maybe a 2 el 40.
