Is there a significant difference between using the galvanized steel
ground rods and copper to create an rf gound?


Hi Bob,

Two answers for that:
1. No difference whatever;
B. Neither make an RF ground.

Updates will follow this brief announcement.

Looks like my follow up post didn't make it through.

Richard I intend these three ground rods to be the start of grounding my
station, not as a counterpoise for one of my antennas. These will be bonded
to my radios and the electrical service entrance ground.

Why do you say this does not make an RF ground?

Thanks, Bob


A lot of folks, make the same mistake, in thinking that Electrical
Ground and RF Ground are the same thing. They, clearly, are NOT, the
same thing or even close to the same thing, unless you happen to be
living on a Salt Marsh. Ground Rods, of any kind, are only Electrical
Grounds. Rf Grounding is a Totally Different bag of cats. RF Grounds
need to be engineered, by someone who is familiar with Antenna Design
and Installation Procedures, for the particular Antenna and landscape,
where the antenna is to be installed.
