Re: grounding

The problem that occurs with some modern water systems as earth, is that
they use plastic plumbing, hence no good earth connection. Certainly where I
am, although the internal plumbing is copper (originally installed 50 years
ago), the plumbing in the street is all PVC! As to copper toxicity, I know a
number of hams who have had problems. Personally I have used large
galvanised water tanks, buried fairly deep, and many others lay insulated
wires under the lawn, but you need lots. The advantage with this latter
method is that you only need to cut slots in the grass with the edge of a
spade, and force the wire down. The grass soon closes over the top. I don't
know anyone whohas used this for TCs though.
