Pat,
I have some friends who are new hams around San Ramon, and I forwarded the
initial email and web site URL to them as they might really enjoy it!
I live in New Jersey, so visiting would be an adventure!
Thanks for the info on the poles and grounding.
BTW: I visited Ft. Ord and the Presidio as an Army contractor about 25
years ago.nice places for duty!
73,

Hello Gordon,
Yes, it was/is special. If you or others want to visit, go to the N6IJ
website, and contact the BOD, to let them
know of your wishes to visit or operate, or join, and they can help you with
that, always with encouragement to Join.
The site is vastly undertilized IMHO.
Most of the Poles had a (some more than a single ) bare single strand
copper, about #8 guage stapled and run from an 8" stinger above the top
of the pole, to a deep ground rod at the base, and in some instances a
pretty good network of ground runners radiating from the pole bases, just
subsurface, and tied to ground rods periodically.
We had some Ft. Ord heavy, galvanized steel pole hardware clamps that were
used to secure antenna rotors and sometimes directly secured antennas, that
I assume were bonded to the existing ground wires at the pole top.
The Big boom homebrew 4 element 20 meter beam (in the website pictures and
on the map) at the top of the hill at 62 ft is fixed to Europe, and plays
REALLY well, now for some 11 years.)
All the best,
Pat Barthelow (916) 315-9271
