[TowerTalk] Ground Rods

[JoeCoolDXer]

A fun thing to do is measure the resistance between individual ground rods in a group, and between any rod and the tower, *before* connecting the ground rods together and/or to the tower base.  In our case, 4 rods in clay soil, damp year around below a foot or two, and having only a good digital ohmeter (but no megohm meter), the indicated "readings" drifted continually from a minimum of like 1K ohms up to over 10K ohms, never did stabilize between any pair, must breakdown/change dramatically during a strike?  Not exactly inspiring of confidence however...have heard mention of periodically salting the area around a tower to make the ground really "play."

Would sure be interesting to know how all the resistance/impedance is actually distributed (and changing) among the rods and tower base during a solid strike...??

  Yeah, and that's a problem, because the code requires 8 feet to be in
  contact with the soil.  [-SNIP-]
