I had a freestanding, 40' Rohn tower for my TV antenna and rotor. The
base section was set in 24" x 24" x 48" poured concrete foundation with
3/4" steel rebar driven outward of the hole before the concrete was
poured. Note that the Rohn tower is heavily galvanized and the base

Am I understanding the rebar correctly ? All of the rebar should be
enclosed in the concrete by about 2 inches. If not, when it rusts , it
expands and cracks the concrete.
