Bob,
Try just using the good variable in series by itself. Often all you need (no omega match)73/Jon AA1K

Greeting Topband Group,
I've been shunt feeding my tower for probably the last 20 years. I've used
a 1000PF vacuum variable and a second vacuum variable for a omega match
configuration.
Last week, I added a 2 EL 40 meter yagi to the tower and removed an OptiBeam
30/40 rotary dipole. Of course, with the additional top loading, the match
is out of wack. When I attempted to adjust the series capacitor, it appears
to be frozen and won't move. Any thoughts on how to possibly fix the CAP or
does anyone have a 1000PF vacuum variable available for sale. I'd sure like
to get this resolved quickly. 73, and thanks in advance for your input.
