Adequate but likely overkill. This was all settled in 1937 by RCA`s
Brown, Lewis, and Epstein. See Fig. 2.19 on page 120 of Ed Laport`s
"Radio Antenna Engineering".

That's interesting. What's a "true earth ground"? What are its
properties? How could you connect an antenna to it?

It is the reference point to which all electromagnetic phenomena on Earth is
at zero potential.

What are its properties?

A magnitude of zero.

With a conductive material.

Thanks. I see it's time for me to leave this discussion.

Sorry if the material discussed herein has exceeded the scope of a US
Extra Class license holder's electronics background.

LMAO.

Just where is this wonderful place? If I were
to guess, I'd say it'd have to be in Texas.
