  You can think of it as a lightning rod without going too
far wrong.

Your other design ideas sound viable if only because
they've been done and work.

Actually the moderators cut some of my more 
outlandish ideas, so i seem more knowledgable 
than i actually am.

  OTOH with some structural fiddling you can omit the rail
as some coilers here will verify.

I have seen a strike rail in several pictures of TC's.
Thanks for the advice on this. I noticed tuneing was mentioned
as a way to prevent strikes. It would seem however that
dielectric losses would be much less with oil.
