Caps for RF transmitting loops, that handle power well?

<< < (8/8)

Gyro:
Relatively cheap for NOS former Soviet ones on ebay though.

Edit, They must be pretty labour intensive to build though, you've got the large glass to metal seals, metal bellows and screw mechanism acting against a fair amount of static force etc.

Eg. https://www.ebay.co.uk/itm/164070350233  (1nF 20kV 100A).

Wallace Gasiewicz:
I used a thick copper pipe for my loop.
It worked.
It was very difficult to bend and did kink.
I used a hydraulic bender.

their main use I think was to determine if we are about to kill each other, so naturally the price drops until another cold war follows ww3 which destroys the advanced technology, then the price will drop when we develop back into current circuits

Wallace Gasiewicz:
Earlier on this thread, I made an error.
My loop is NOT 10 feet dia
It is 10 feet in Circumference, one piece of 10 foot copper pipe.

SORRY SORRY SORRY
