What is a good variable capacitor to use with this coil? Any links would be appreciated.

The only thing I can think of is where I took a 4" coil which was wound for a crystal radio and connected it to a mini variable capacitor. It provided a good little boost for its size, and the Litz coil and special basket weave meant that the Q, or tuning sharpness, was very high. The seller on ebay currently has a similar coil (see ebay item 330448576470).
Hope this helps - Kevin
I recall that you built a very small loop antenna of about 4"-5" diameter.
Is there an article describing the construction of this antenna? I
couldn't find it on www.dxer.ca with all of the other ULR antenna files.
