I just scored a 1000pf @ 1.2KV antenna loading variable for the 813 amp project. I'm going to get some HV micas to parallel with the variable. I want to get the total loading cap to around 2000pf and need a shorting ceramic switch that can do the job such as a 3-position progressively-shorting rotary switch (Centralab P1S wafer).
