Integrated Tuning for 160 and 80 meter Dipoles and Verticals
Presenter: Nelson Sollenberger, KA2C
Simple and low-cost techniques are presented to remotely step tune 160 and 80 meter antennas for high power operations. See CQ Magazine Aug, 2023. An 80 or 160 meter inverted vee is equipped with a small antenna center unit providing 8 frequency steps across the band with worst case SWR of about 1.5 to 1. An 80 meter vertical is step tuned with a modified Ameritron RCS-4 remote antenna switch at the antenna base. Components and design tools are discussed.
