[Elecraft] OT - Source for Air Variable Capacitors

[Walter Underwood]

Here is a link to a butterfly capacitor at Radiohaus, without the eBay middleman.

It looks nice, but I’m not sure I understand what they mean by the three different capacitance ranges. The normal mag loop configuration would be to connect the two stators to the circuit and leave the rotor floating, so I guess it is a 15-120 pF variable.

• Stator - Stator: Aprox. 15 to 120pF
• Stator - Rotor: Aprox. 20 to 250pF
• Rotor - Conected Stators: Aprox. 40 to 480pF
