Seriously doubt you'll get away that small for a 80' monopole. Would guess
something more in the order of 10x10 and 8 feet deep for that type of
application, probably 15 or more yards of concrete. My PE is looking at the
base size for my new tower, looks like 8.5x8.5 and 7' deep for 56' self
supporter according to wind loads and uplift for Mass. building codes.
