Guys, all this analysis is good, but the simple fact remains that w/25G &
the Rohn AS25G, there are only
two places where the rotator can actually be mounted! Either at the top
"opening" or at the lower section
joint. I have always operated w/the rule of thumb that 1/3 of your mast
length should be inside the tower.
No failures in 50 years, leastwise mast-related, so that seems to be

There's a lot of science involved here, there's a lot of common sense
required, & there's certainly no
substitute for practical or professional experience. Based on what I've
seen over the years, 25G is the 
closest thing we have to a "universal tower," & the design is quite
forgiving when it comes to many ham
radio installations....have the tee shirts...
