Ron,

I just moved in to a new home in GA, what I noticed is that the 
electrical contractor tied to both an external ground rod plus a second 
tie to the rebar used in the basement walls.  My basement is poured 
concrete and when the builder was installing the rebar I noticed that he 
had ties between the different sections different from the normal ties 
between rebar.  As I understand it there is a NEC code requiring this 
type of connection.  Is it good for lighting or bad I do not know.  
Guess only time will tell.  I did not have the builder tie the rebar in 
the tower base pour and my plans are to use three straps and separate 
ground rods plus a field of radials with additional rods at the ends.  I 
have started the rods at the house and plan on at least four plus tie-in 
to the power common point ground rod.  Got my rods at Home Depot and I'm 
sure there like Lowes

Good luck with mother nature.
