Hi Fifty,

Ok, I overlooked the capacitive coupling, big error. This brings us to the
salient question: What is the safest way to route the low voltage wiring
from the controller/user to the HV section at the coil. My impression is
that all HV stuff should be RF grounded although not all agree under certain
circumstances, for instance the pig ground. Clearly the center post of a NST
safety should be RF grounded for safety but what of other scenarios?
Grounding a shield at both ends invites ground plane problems, Yes?

I'm about to go high power, is there definitive answers to these issues?

     It doesn't have to penetrate, although I wouldn't want only 1/4"
of plumbing-grade PVC between myself (or home wiring) and 400kV of even DC.
     All it has to do is capacitively couple. Slip a piece of your
Sch 80 PVC over your ground rod target (cover the rod end well),
mount the rod on a well-insulated/elevated stand, and leave a small
spark gap at the ground connection to the rod to see if any streamer
current jumps across.
