[time-nuts] Potting compound advice needed

[Richard (Rick) Karlquist]

I am looking for help choosing a potting compound that
has the following properties:

1.  Good for 5,000VAC @ 1 MHz
2.  Low RF losses.
3.  Low permittivity is preferred
4.  Low tempco of permittivity is a want.
5.  Something I can implement in my home shop
without access to a vacuum pump etc. is a want.

Thanks in advance
