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

Cool It
I have owned an AT-AUTO since they were first released and its given good service. One area that it let me down was 10M

Current Through a 75m Bugcatcher Loading Coil
Many experiments and measurements have been made on loading coils using net standing wave current
