WebSep 2, 2024 · While the EFHW is a resonant antenna and in my case, cut for the 20 meter band, I do like to utilize other bands. There are two major ways to accomplish this. The first method I used was to unsolder the … WebBecause the feed point impedance of an end fed half wave is high the current must be low. For 100W carried it's in the 0.25A or less range. For example 1600 Ohms x 0.25A 2 is 100W. 1600 Ohms would be on the low end for an end fed half wave. The current at the connection point to the unun won't be significantly higher.

If you inject AC (rf) into one end of the center conductor, the current flows on the outer most part of the wire. Very little of the RF is conducted along the length of the wire in the inner part. As a matter of fact at 3.5 MHz, over 90% of the rf is conducted along the outer nominal 40 ...
WebDec 22, 2024 · With an EFHW the antenna resonates on all harmonic bands with a good match, so using a 40 or 80m version and adding wire to resonate on 160m will in effect parallel two antennas operating on the same bands and pull the feedpoint impedance down, plus you will have RF currents flowing in different directions at the same time causing …

No, it is not needed, but it can improve the antenna system. An EFHW is simply a half-wave length of wire and a matching device, and that's it. Counterpoises are commonly added to shunt common mode reflections when operating outside of the wire's resonant frequency to avoid RFI issues ("RF in the shack"). south park lil crime stoppers script
