Is a nice station grounding pdf from Polyphasor. Sorry for the tinyurl,
the original url is a mile long.

Everyone should have a copy, and the writer should get an award for his
or her clarity.

That's a good article, but it is focused on grounding for lightning
protection. I am interested in
that, but I am also interested in having an effective RF ground.

I've been able to get a total of 16 feet of ground rod down in the form of 4
four-foot rods, but I
have a 50 foot run from my office to the ground rods, and I'm concerned about
RF impedance in that
connection.

The two are pretty much Mutually Exclusive. What makes for Good
Lightning Protection, really doesn't have ANYTHING to do with RF
Grounding, especially if your using an End Feed Vertical, for an
Antenna. Lightning Protection is a Ground Rod that meets NEC.
Low Impedance RF Grounding System design is a Science and Art all in
itself.
