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
Homebrew Your Own Inductors
Air-dielectric inductors can be made quite easily at home
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
