While on the grounding topic... why do some sources recommend burying the
wire clamp to copper ground rod connection a minimum of 6 inches?

I am in the process of erecting an HDX-555. I have the hole dug and most
of the rebar cage built. My question is about the best method of
grounding. Should I place a copper cable at the bottom of the hole and
then attach it to the tower? This method would have the cable immersed in
the concrete which makes me wonder about that much heat going into the
concrete if lightning hits, even if it is just on the edge of the
concrete. The other method I am thinking of would be three ground rods
placed around the tower and connected together and to the tower with
copper strap and/or very heavy copper wire. Just looking for input from
the collective knowledge of this group as I am in a lightning prone area
in west Texas. Thanks.
I have #4 copper connected to each leg of my HDX-555 (with
stainless-steel shims as separators to avoid corrosion), and each
running to an 8ft. copper-clad ground rod about 10ft. away.
