This is one of these questions that comes up periodically for which
there is no simple answer. First, what do you mean by "ground
resistance"? Electricians and power companies are mainly interested
in a measurement at 60 Hz. Hams with vertical antennas are interested
in the resistance at the frequency of operation. Folks interested in
lightning protection have a foot in both camps as lightning has a
large RF component.
