A low impedance tower ground is important. Google TOWER FOOTING RESISTANCE
for an IEEE ppt. on this. I would aim for a couple of ohms. That means
several long rods.

Dave,
Of course a low impedance ground is important.
I have a ground field with 6 - 10ft 3/4 inch schedule 80 copper tubing. They
are
buried with the tops about 12 inches below the surface. The
ground rods are all connected with 1 1/2 inch copper strap and to the ground
plane in the arrestor box. The ground plane
that the arrestors are mounted is 12 X 18 X 1/4 inch copper plate. There are NO
soldered connections. Only thermo-welded or screwed
together. There is "NO-OX" in the screw connections.
For safety reasons, the tops of the ground rods MUST be below ground,
