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.
