OK, likely a couple of 47 pF doorknobs (or about 86 ) could be used for
replacement.

Thanks, w9gb

I have the manual for the R3, and I think the variable capacitor/motor
is OK. The part that needs replacing is a small coupling block
between the actual SO-239 feedpoint and the stubs that go to the
ring. The parts list calls it a matching network assy., so it must
contain some series capacitors, or something. I contacted Cushcraft
with no success...too old of an antenna.

Anyway, I will probably be moving to a GAP antenna. This one has
served an OK life.

Thanks,
