Re: [TCML] open ring substitute...

I would think that "EM transparent" and "electrically conductive" are mutually exclusive in the frequency ranges we are dealing with.

I've never tried it myself, but I suspect that any electrically conductive material would act like a shorted torn, no matter whether it is a copper or aluminum ring, or a piece of wire screen.

I have seen several spectacular museum photos of electrical discharges passing around an insulating glass plate.

I suspect that a simple circular piece of 1/4 to 1/2" Lexan of sufficient diameter would divert a direct strike, but the diversion might be TOWARD the secondary, which would not be good.

Perhaps a large circular plastic disc, big enough to completely shield the primary, and then some, with a grounded, gapped conductive ring below the bottom outer perimeter might work well.

Ok, now you've got my attention.

instead of an open ring or even a closed ring, how about an EM transparent
but conductive  "curtain" to protect the secondary?

I was thinking something on the lines of Carbon fiber fabric held in place
with some type of plastic ring assembly...

just a thought  :)
