And remember that as far as lightning is concerned, INDUCTANCE can be a far
greater factor than resistance in limiting the speed of discharge (and thus the
voltage buildup). So follow basic circuit concepts -- multiple short paths in
shortest possible paths, bond everything as well as you can, etc. I would sink
copper strap under the foundation taking a direct route from tower base to
ground rods in addition to multiple rods around the area, and all bonded
outside the house.
