Up to 40 feet free-standing for 25G. And 45 feet for 45G. 1.5 and 2.3 sq
ft max wind loading. Pretty much useless.
6.4 sq ft for 25G at 30 feet. Not bad, but I still wouldn't do free
standing. I have a 40' 25G bracketed at 16 feet at my house. It has my
3.6 450 SM on a reflector near the top. It moves quite a bit in the
wind. I've already had to replace several bolts that worked their way loose.

I never went to 40 unless it was against a building with brackets.
Otherwise 20 feet was my unguyed limit.
I do think Rohn said you could do 40 but I don't know how much wind
loading area you could add.

Subject: [AFMUG] Un-guyed tower
Just for clarification, what are the maximum heights, if any, for
un-guyed Rohn 25 and 45 style tower sections? The rumor I've heard is
40 feet. Is this true?
