I have a Rohn catalog I purchased last month from Champion Radio
(presumably the current version) which has the fold-over information.
For a 48-foot 25G fold-over, it shows the safe load at the apex as 130
lbs. With guys at the hinge only it is rated at 6.2 sq. ft. for 20
psf and 3.0 sq. ft. for 30 psf. With guys also at the apex of the
tower, these numbers are 13.3 and 7.7 sq. ft., respectively. Other
towers in the catalog are rated for wind speed instead of psf, so I
guess the conversion is "left as an exercise for the student," as my
professors used to say.
