I have a 20m inverted-V dipole with 1/4 wave 300Ω twinlead as the feedline from the center insulator to a 1:1 current balun mounted on my wall (the twinlead is transparent at 20m frequencies). The other antenna […]

Katie Bouman and her team did an amazing job! What’s less amazing isn’t the reporting that Dr. Bouman was the technical lead on the […]
