Hi Jim, Thanks for the reply.
I just purchased the Grounding and Bonding book Saturday and have been
going through it. I found your material about 6 months ago and I've been
studying it since then. That is what impelled me to clean up my shack
and put in a SPG. I'm not having any RFI issues in general. I just want
to put in an effective ground system for Lightning, AC and RF.
The cable length question is more of a preemptive strike. Seems there is
always a cable somewhere to deal with.
Thank you so much for all your efforts in this group, and the materials
that you have made available to all of us.
