Most house grounds are just a piece of re-bar hammered into the soil,
andthis is done before the foundation is poured around it. Ours is
barely visible except for the big chair clamp that secures the bare #8
wire to it. I've seen it other ways too, for example in the upper
midwest. The ground we had in Iowa was three copper-plated rods within
about one square foot, all bonded together. Not sure why anyone would
do that, but the builder did the same for all houses in that development.

Hi,
This is totally off topic; I apologize.
I just received the new ARRL publication "grounding and bonding for the
radio amateur". It is very interesting reading. I see that the NEC requires
two ground rods for regular power installations; never mind any antennas. I
swear that when when I moved into this house there were absolutely no ground
rods installed. I just inspected our power pole that supplies our power. I
could see no wires going in to the ground. So I have no idea where our
"green wire" came from.
But I have have installed two 8 foot ground rods to ground my antennas and
they are bonded to the AC entry panel. But what's up with this? I bet my
neighbors have no ground rods installed either.
