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?
