Trap dipole antenna
My trap dipole exists in the form it does because, like many of us, the garden is too small
Traps-about antenna traps
It contains measurements of traps, performance of trap antennas using models of traps, and ideas on how to make trap antennas more efficient
Traps antenna 40/20 meter
More than 5 years ago I already made a few cheap traps and put a small piece about it on my website
