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 WX7G 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, Electrical Code in St. Louis County.
