Cushcraft Trap Coaxial Capacitor Repair
There are occasions that the coaxial capacitor on Cushcraft trap R5, R7, etc. fail due to a breakdown of the insulator between the outer aluminum tubing and the inner capacitor rod

The wire used is an enamelled copper wire with a diameter of 1.9 mm and a length of 3 meters, often used in transformers
High-Q Coil Construction Techniques
High-Q coil inductors have something in common: the length of the coil can only be slightly longer than its diameter. In other words, high-Q coils have cube-like dimensions
Helical Coil
The inductance and self capacitance of a helical coil can be determined by entering its dimensions in the boxes above. The length of wire used is also calculated
Inductor resonance experiments
Methods for determining the resonant and self-resonant properties of coils
