Bought two 1200 pf 4 kV for use on big 160 antennas out at N4AF, from
QRO-stuff. No problems and have done the job out in remote box for
seven or eight years now. Very stable. Quite large, drive shaft is
NOT 1/4, 12mm or almost 1/2. Most likely have to fabricate a knob or
reducer.
Those big things are the final answer, absent direct lightning
strikes, for going the distance QRO. Prices for Jennings brand new
retail are simply awful new, but on eBay the Russian listings are
affordable. This is most like what we bought:
