WebMar 26, 2024 · The popular End-Fed Half-Wave (EFHW) Antenna is an easily portable, high-impedance (2,000-4,000 ohm) wire antenna that resonates on its fundamental frequency and all harmonics above. Several ways exist to bring the wire’s high impedance feedpoint closer to the desired 50 ohms, including use of a 49:1 or 64:1 unun, which …

End Fed Half Wave or "end-fed dipole" Antennas

WebAn end-fed half-wave (“EFHW”) antenna has a very high feedpoint impedance, often 1000 to 5000 ohms (depending on the diameter). The radiation pattern on the fundamental frequency (where the antenna is 1/2 wavelength) will be similar to the same wire fed in the center as a dipole (but this is not the case on harmonics). Webof NOT hanging a heavy coaxial feeder from a long span of thin antenna wire, has rekindled interest in end-fed half-wave antennas. The 25m long antenna described here will get you on air without an ATU on 80m, 40m, 20m, 15m & 10m. It has been purposely reduced in length compared to a full sized 80m dipole by the insertion of a 70uH loading coil. WebAn advantage of end-fed antennas is of course the simplicity, especially for fieldwork this is a huge advantage. Put a telescopic mast against a pole, hook the antenna to the top and slide it out. You are on air within 5 minutes! An additional advantage is that the antenna can easily be polarized vertically. east meadow teacher salary scale
