I am using a pier pin base because that is what my county requires. When
looking at Rohn's manuals and drawings a tower section buried in the concrete
is used for a self supporting tower max height 40'. Rohns manual for guyed
towers only shows a pier pin base, therefore the county will not allow me to
use the tower section in the base. I argued that the foindation was stronger
but a no go. I must use what the county will sign off on.

Rex,
I am wondering why you are using the pier base? I believe that unless you are
going really high it not necessary. In most installations that I have heard or
know of, the guys just bury a 4 - 5 ft piece of Rohn 26G in concrete and build
from there.

I thought Rohn 25 should be guyed every 20 feet. If you are not using a wall
bracket then I would install 3 sets of guys.
