An Attic Coaxial-Cable trap dipole for 10, 15, 20, 30, 40, and 80 meters Trapped dipole for 40-80-160 meters Build a space efficient trapped dipole antenna for 40-80 Today we build a multi-dipole array that will work on 80-40-20-15 without a tuner. With a tuner, it should load up just about anywhere and might even work . Introduction: In November, I got a call from a podcaster.  His name was Gabe.  He was curious about fusion.  Gabe “…want to do an energy show and contrast fusion with new fission.  I honestly know ver….
