Jim, lets stop talking about grounds totally when dealing with RF, it's
just a confusion factor when it comes to discussions.
That's what I said.
unless we are
talking about as NEC and others when they correctly call it a "Safety
Ground" or a "Grounding Conductor" and make sure that everyone
understands the difference.. most don't
discussions should be about
Safety Grounds, and grounding conductors 100% about 60 cycle and DC currents
common connection points 100% about how the above are connected
counterpoises, radiating elements: deals 100% with RF and antenna's
etc.. properly understanding each one and you won't be confused at all..
I've written extensively on this topic, and both that writing and
several slide shows are on my website. k9yc.com/publish/htm
I also disagree with your statement
"First, and most important, for lightning protection and electrical safety."
The first and most important item is an electrical Safety Ground as it
protects people, they can't be replaced.
Second is lightening protection, as it typically protects equipment.
equipment can be replaced
Again, I refer you to my website.
They don't carry the same weighting factor.. as very few worldwide are
killed from lightning vs improper safety grounds.
They are not different. Again, see my website. ALL grounds in a premise
MUST be bonded together. PERIOD. Power entry, Telco entry, CATV entry,
antennas, shack, etc. These connections must NEVER be separate or
independent of each other.
most likely the only thing we don't agree on.. everything else you seem
spot on...
I think what you view as disagreement is my failure to write well enough.
