Wideband Coupled Resonator Dipoles and Verticals vs Dipoles with Integrated Step Tuning
The following attachments document a PCB and design for a simple 3 inductor remote tuner for 160, 80 and 40 meter dipoles, inverted vees and vertical antennas capable of 1.5 kw operation. A BALUN or UNUN at the input of the tuner provides impedance matching. Schematic, PCB, and gerber files for fabrication are included in the Tuner PCB design files attachment, and PCB’s are available at low cost from JLCPCB. EZNEC design files for 21 different 160, 80 and 40 meter antennas are included in the Tuner Antennas attachment. This tuner supports full band low-SWR coverage on 160, 80 or 40 meters with simple antennas which can be reduced size using bent legs or tophats as well as full-sized antennas.

This article describes a bias tee with a 4th port for 2.4 GHz IOT remote control multiplexed on the shared coax from radio shack to tower top with 12 VDC power up to 2.5 A and the transmit RF at up to 1.5 kW for HF. It also includes ESP32 based control and remote Arduino devices and a tuning PCB. Files for PCB schematics, Gerber files, software and other documents are available at QST-in-Depth.
