Illustrative of the difficulties of doing the single-point ground thing
properly with an old house, our telephone and cable TV connections are 180
degrees around the house from the AC power entrance, grounded to a rod at
that point, so there is undoubtedly a fair amount of resistance between the
two grounds. Just to further complicate things, our telephones are in
parallel to the telco box rather than in series.
I would have to trench in a perimeter ground, per Polyphaser
recommendations, before anything else would begin to make sense.
