hat I don't know is the relation between radio and other electronic
equipment and a lightning rod installation. For example, do you bond the
radio grounds to the lightning rod grounds? At ground level, or anywhere
along the wire?
Too bad I can't find my copy of N0AX's book on the subject. Need to do
more digging.
Hi Bill,
Here are slides for a talk I've done at Pacificon, Visalia, NCCC, and
other local clubs. I worked extensively with Ward on the book. While I
was still working, I gave tutorial workshops on the topic to companies
installing large sound and video systems.

The short answer is that EVERY earth connection MUST, both BY LAW
(electrical safety codes) and by good engineering practice, be bonded
together. More of everything is better. :) That means rods, building
steel, metallic cold water plumbing, entry for power, telco, CATV,
antennas. It's also critical that all equipment that is interconnected
be bonded together. That means short, fat copper.
