End-fed half wave antenna

WebThere are two main benefits in using an end fed half wave antenna over a coax fed half wave dipole. The main benefit is that the antenna feed impedance is around 2500 ohms and very little RF current flows into the RF earth or counterpoise. In many applications the coax feed to the antenna matching unit will act as an efficient counterpoise. WebApr 5, 2024 · HOA Stealth antennas are a must for me and the end fed wire antennas are my best bet it seems. I also found the link to Steve Dick’s (K1RF) “The End-Fed Half-Wave Antennas” guide to be the icing on …

WebJun 13, 2024 · A common half wave end fed antenna is the J-pole or the end fed zepp. This antenna uses a quarter wave open wire transmission line as an impedance transformer. The transmission line (of any impedance) is shorted at one end (Z=0) and open at the other (Z=infinite), and a feed point is placed in between where Z=~50. ... WebThis is an End-Fed Half-Wave (EFHW*) antenna for 80/40/30/20/17/15/12 and 10m bands. Unlike many END FED antennas on the market, this one does not require the Antenna Tuner to operate.
