Looking at the Rohn base specs, I am quite surprised at the requirements,
assuming I read it right. For a base, without piers, the specs call for a
14'-3" X 14'-3" X 4' concrete base ( 30.1 cubic yards).
To me that seems like considerable over kill.
My tower has 8N, 7N, 6N, 5N, 4N, 3WN and 2W sections.
I looked at a 140' SSV installation a few miles away from here and that base
is 7'-9" square. I don't know if that sets on piers or how deep it maybe.
Any qualified comments would be appreciated, before I start digging.
