I, for one, wonder how good my service entrance ground is...mine is probably 20 
years old, and while the top looks ok, there's no way to know what's going on 
down 4, 6 and 8 feet...my utlities are underground, if that means anything...
as a starting point, should a guy drive a new one? or 2 or 3, spaced some 
distance apart?
( gosh, top band sounds lousy this fall, for me, anyway...sigs are well down 
from normal strength..)

 I'm in the process of setting up my station in a new QTH and plan to
install a station ground at the cable entrance.

Tom, is there a best practice for bonding to the mains ground? Any
approaches to avoid?
