The bracketed information is probably in your Rohn catalog. The
drawing number is A871302R1 for 25G and it's been around since 1988.
If not, Rohn has published a handy little pamphlet that contains all of
the bracketed and free standing specs for 25G, 45G and 55G called
"Manufacturer's Technical Information for Bracketed or Self Supporting
Towers". I refer to it all the time. For a free copy of it, send an SASE to
TOWER TECH, Box 572, Woodinville, WA, 98072.
As with any potential tower installation, the first thing you need to do
is find out the TIA-222 wind speed rating for your county and use that to
make all your hardware decisions. I have a copy of the TIA tower spec and
can look it up for you.
