>From memory and may not be 100% correct:
Rohn 25 legs = 1.25" dia
Rohn 25 crossbraces = 5/16" dia
Considering 3 legs, and 3 crossbraces for a cross-section (not 100% correct),
the area is 4.6875 square inches.
And, if viewed from the correct angle, one leg and one brace is hidden,
for only a 3.125" obstruction!
