Yikes, I hope you aren't digging it by hand! Better hurry up and hope you
don't hit rock!
(I have a rock layer here at 40" down.)
As for your original question, I find it amazing how requirements have changed
since I got my license (1963). Look around at all the towers standing for 30
years and I'll bet they don't have high strength concrete and complex rebar.
They just won't last.... ;-) Seriously, I put up a 64' freestanding
Heights tower twice in 1970 and 1975 and hand mixed the concrete (two days on
the first one using Sackrete) and it only needed a 4x4x4 base back then with a
TA-33 tribander and other antennas on it.
I do think the lawyers have changed the engineering specs over the years.
Good luck digging,
