166.5kc. Bill Ashlock told me that the variable cap is a small part of the
total capacitance so there will be only a bit over 1/2a in the variable cap.
I do need to have a voltage rating of 2.5kv. This is for a 400w transmitter
and a big transmit loop for a Part-5 experimental station.

I would like to know if anyone has built variable capacitors for
transmitters or tuners. I would like to build a variable capacitor that is
at least 100pf and can handle 40 amps of RF current. Does anyone have any
ideas or links to some articles???
Thanks es 73's,

Dear Mike, LF group,
What frequency is it for? Surely not LF - at 185kHz, the voltage rating
might be a problem - about 340kV with 40A!
