With a radial system or mesh system, you are merely fabricating an
artifical counterpoise loosely connected to earth that may give one
the perception that true theoretical 'ground' is achieved, depending
of course upon the frequency in question. A connection to earth mass
with a rod that has copper copper cladding that reacts with the ph of
the soil forms an oxide or hydroxide compound that makes the steel in
the ground rod electrically homogeous with the surrounding soil,
rendering the electrical potential of the steel in the rod at "zero"
with respect to RF radiation potentials, lightening, the power
generating generating station or conduction of electrons in any sense.


Do you sell copper clad ground rods?

With your creative explanation, you have missed your calling if you don't!

What you have learned is that "Ground is NOT Ground, the World Around"
an Old Radiomans adage from an earlier generation. Power Distribution
Ground is not the same as RF Ground, and mostly the two are Mutually
Exclusive.

You ask what makes a better "RF" Ground than earth itself? That is
very simple. Ocean Sal****er makes a much better RF Ground, than
anything you have, or can build, on earth.

Mostly Bruce is right. But, I`ve worked in many broadcast plants and can
assure you that the radial grounding system is more than adequate as a
power distribution ground except for code compliance which may require a
ground rod and/or connection to a metallic water pipe. The radials are
the best RF ground.

Now, there will be a body of opinion that it doesn't matter what you
do, you will still get QSOs, that it therefore 'works'. It sounds from
your question that you are more interested in that shallow level of
engagements, so read around.


That didn't come out right... it should have read:
