The German company Draloric makes some great ceramic HV feedthroughs and bypass
caps. For lower frequencies, they have a high K dielectric that yields large
These parts will work into the MHz. For VHF use the lower K dielectric and they
don't go self-resonant until above 200 MHz.
They are now owned by Vishay, and Richardson is the distributor. Not cheap
