Sorry bill, I was trying to make a clearer statement out of what you
were quoting from the article. If that is exactly What they are saying
then the article doesn't make sense. Maybe you are reading into it
something that they are not trying to convey?
I read it as saying that neutral is only connected TO earth at the panel
and the transformer. Maybe I am reading something into it?
As far as single point grounding is concerned as hams refer to it, This
really has nothing to do with it. The idea with the power line neutral
and ground is to never have the ground carry any neutral current.
With single point grounding for the antenna / power system the idea is
to not have ground paths through any equipment to ground.
