Here's a variable capacitor with the reduction drive built in.
This has a 5:1 reduction ratio. 380 pF max $18.00
Gear and ball drive reduction - 12:1 total reduction ratio.
18 pF max $15.00
5:1 reduction ratio. dual section 420 pF max each. $ 20.00
Lots more variables to come as I get them photographed and posted.
I've a number of 450-550 pF caps which should make it easier to build loop
antennas covering the entire BCST band in one range. Inquire if you are looking for anything in particular.
