He uses two link coupled tuners.......The big Johnson Viking for 75
Meters and a homebrew unit for 160. His main concern is static caused
by blowing snow in the winter, not lightning. Enough voltage to arc
across a PL259 with a loud SNAP. For this purpose the plate chokes work
fine.

Bob, that only works with the true link-coupled tuners, such as Johnson
Viking, or Annecke.
But most people don't have those, so they're hosed.
I wanted to post how I do it but can't find pictures.
It's late here, so I'll search for pictures tomorrow.
Annecke used to sell some outstanding solutions to the grounding problems.
I still own them, but unfortunately you can't buy them new anymore.

Yes, but lightning is not DC. It is a series of short duration pulses
resembling AC and should be treated accordingly with little to no
inductance in the path. Thus any inductance in line would actually
Another option is to use a pair of plate chokes from each half of the
feedline to ground. I have a friend up in NH using this setup. Keeps
the antenna & feedline DC grounded. Lightning isn't his big problem,
static electricity generated by blowing snow was creating havoc at his
station. The chokes solved the problem.
