TopBand: Caps for antenna matching

[Greg Smith]

Here in South Africa we can buy Teflon sheet 0.3 mm thick.  This has a
voltage rating of over 10 kV, and a very low loss tangent.  Rolled between
layers of brass shim stock, it makes good low loss capacitors.  Just leave
enough Teflon protruding out of the ends to prevent tracking across the
surface.

I'm sure the same material must be available in the US.
