An Attic Coaxial-Cable Trap Dipole for 10, 15, 20, 30, 40, and 80 Meters
A coaxial-cable trap dipole antenna installed in the attic provides a surprisingly effective solution to HF operation on the 10, 15, 20, 30, 40, and 80 meter

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

Noise suppression with X-phase II This device similar devices are known as QRM eliminators or noise killers, makes it possible
The K9AY loop antenna for 160 and 80m bands You don't have the space to put up a 4 beverage antenna's, an ewe or a 4-square and want 'good ears' on 160 and 80m? no problems try a k9ay loop antenna
