Hi All
Picking up on John, ZS5JF's comments re HV multi-layer disc capacitors =
in place of silvered mica - are these ok for RF? Farnell and RS do a =
range of HV resin dipped disc ceramic capacitors up to 15 kV which are =
not expensive. I am wanting to build a high power, low pass filter for a =
8877 6m linear and had considered these but was unsure if they were ok =
for RF. Other than this I was considering door-knob caps but these are =
not easily available at reasonable prices in the UK.
Any advice and comments would be appreciated.
