[TowerTalk] Grounding HDX-555

[Brad Hyde]

Hello all, 
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.
