I used a much simpler alternative: a short piece of "air core" coax.

The total capacitance is obviously proportional to length, so cut a length that corresponds to your maximal required capacitance. To adjust, simply pull the centre conductor out of the coax shield as far as is required. Job done.

Ok I see.

And when the pic is bigger you don't look like Jim.
Thanks
