We, or most of us, do use rebar, but it is used to reinforce the concrete
and the ROHN catalog has instructions on how to arrange (lengths and bends
to make) the rebar.

I'm a firm believer that they should not allow the construction of any home
without a basement, or building on land where you can't have a basement.
(I've lived in tornado country far too long) <:-)) If I built in florida
I'd have to find one of the few hills, or build my own so I could have a
basement.
With tower guying we depend on the weight to hold the tower and the guys.
Hence the large amounts of concrete in large holes. Rerod used as you do
for home on a slab would likely cause the slab to be blown to bits on the
first hard lightening strike. OTOH, some station installations depend on
large areas of reinforced concrete to provide a ground. I have forgotten
the name of this procedure, but I'm sure one of the engineers on here can
fill us in.
