Build Your Own Transmitting Air Variable Capacitors
As I was building my transmatch, I became increasingly dissatisfied with my choice of capacitors. They were too small for more than about a hundred watts, and the ganged capacitor was in pretty sad shape

Coaxial Traps forMultiband Antennas,the True Equivalent Circuit
Multiband Antenna DesignParallel-resonant circuits calledtraps are widely used to isolate partsof multiband antennas to make theantenna resonant on different fre-quencie
COAX traps
Coax traps are cheap, easy to assemble in a reproducible manner, very rugged, perfect for portable or permanent operation, on dipoles, inverted-V's etc
Coaxial Traps
The Coax trap program computes design parameters for the construction of coaxial traps for HF usage
Coaxial Traps Grid-dip meter method
A trap is a parallel resonant circuit network that can perform either of two functions in an antenna system, depending on whether the traps are resonant at the operating frequency
Coil Design
The coil design is one of the most difficult and important parts of the coilgun
