I am totally amazed at how concrete has weakened over the years.
When I put up my 64' UNGUYED Heights tower in 1970, 4'x4'x4' was all
that was required and that held a tribander and other antennas for years
(rebar wasn't mentioned and it was hand mixed concrete). For a 50'
guyed tower, all I used was 30" square and 8" deep.
But that was back before we had modern computers to tell us it wouldn't
work.

Rohn recommends more. 3 ft x 3 ft, 4 ft x 4 ft. More mass in the
ground is better when the wind blows.
