I used nine aluminum wires, connected three each to the three tower legs. The
connection is "up-in-the-open". I did this to avoid el.-corrosion. I don't know
if it is so important. Future will tell. I used steel grounding rods.

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.
