Hi,
Plausible that concept is already in plan, yet I was thinking of single point grounding panel (SPGP) in shack. Everything needs to go thru it including mains, CATV, Ethernet, coax switches mounted on panel, buss bars to which power supply, rigs, tuner are attached. That panel is bonded to ground rod where coax enters house with bonding to service entry ground.
We have whole house surge protection here in the main breaker panel. Eaton is mfg.
If not already in your hands, recommend ARRL publication Grounding and Bonding for Radio Amateur (Amazon or ARRL). In my case, I worked thru the book before hooking anything up. There are lots of ways to get there, and well-done for thoughtful ground planning. Beg indulgence if I’m not interpreting or missing some of your details.
