I have had very good success with chicken-wire for a ground-plane, but I
have plenty of real estate available.  Trees are definitely BAD.  You might
want to put the insulated radiator on top of the metal building and use the
building metal for the ground-plane.

Greetings:

I would appreciate a discussion on what is the best ground, under the
following limitations.  Yes a salt water marsh is wonderful but I live 600
miles or more from salt water and that is not practical for me.  Next, I do
not own enough land to make a really good ground like I have on 160.

What I want to discuss or watch being discussed is how good might a
connection to the ground used by the Electric Utility transmission system
be?  A ground to a railroad line (the cold side not the hot side of the
rail)? A large building with a metal roof.  What else should be considered
as a good ground.

One I just thought of would be an abandoned Broadcast Band transmitting site
where the screen is still in place.

What are other candidates for a great ground system?

What is behind the question?  Well if the regulator specifies the length and
input power of the lowfer transmitter and does not discuss the ground
situation , then if one wants to move the end result around then one has to
work on what is not specified.  The regulator does not discuss the ground
system thus this question.
