20 linear feet of metal (of a particular size rebar or copper or alumninum) is
the code requirement. I would think the standard tower base rebar probably
meets that standard.

There are a lot of white papers out there that advocate various approaches, not
always with good backup other than
"seems like a good idea". At risk of throwing gasoline on a fire.. contemplate

I can't see why you'd want to bring any conductor out the side, although if
it's above grade, it might be ok. The concern is with being below grade in a
moist environment.
