End-Fed Half Wave Antennas
Steve Dick, K1RF, does a deep dive into End Fed Half Wave 9EFHW) antennas. He shows you the components needed to make a multi-band EFHW antenna resonant on 80, 40, 30, 20, 17, 15, 12, and 10 m with a low VSWR. Steve provides construction details, as well as part numbers, for the needed UNUN transformer, compensation coil, choke balun, counterpoise length, and compensation capacitor. Just about everything you need to know about EFHW antennas is right here.
