Howdy, TowerTalkians -     I'm interested in putting up a wire antenna that I can use on HF. The myantennas.com EFHW-8010 looks interesting. This one claims No tuner required.  I'd also consider an a

Ive used the EFHW-8010 over the last year at 100, no counterpoise, and have confirmed 98 entities on Lotw. Mark K6UFO just suggested that a counterpoise is needed: <https://www.w8ji.com/end-fed_1_2_w

Hi Steve, In what environment will the antenna(s) be used?  That is, are you in the middle of nowhere, or do you have neighbors with noisy electronics? My estimate is that the average home has at lea

The EFHW-8010 gets rave reviews, but I'm fundamentally suspicious of any antenna that covers that wide a range without tuning.  There have to be losses somewhere to get that. Those same reviews also

This is one of those dumb ideas that can be fed to those who think an antenna "works" if the SWR is low.  "Works" is better defined as plots of field strength vs angle, COMPARED to a known good anten

John KK9A A 6 dB pad in series with any antenna will need no tuner or counterpoise to provide a better than 2:1 VSWR. In general, if there's a skywave path at all, the 6dB probably won't be noticeabl

I've long been a fan of the EFHW for portable operation, but I've always used a tuner. There seems to be a lot of aversion to tuners. If you can get over that, many possibilities open up. A simple L-

John KK9A I've done a fair amount of work with end fed half waves. They make a fair amount of sense on the frequency where the wire is at half wave resonance. On the frequency of full wave resonance,

Beyond that, the marketing idea of a multiband end fed wire is just a fantasy.  The pattern on the higher bands will be full of lobes, and the drive impedance will be all over the place.  Ignore rev

For an end fed wire, this is not true. Its pattern has 4 lobes, a cloverleaf. It is like a full wave fed 1/4 wave from one end. That's two half waves OUT of phase. A center fed full wave is indeed tw

That is correct.  Phase flips every half wave as you travel away from the feedpoint. At one point in the past I had a 160m Inverted-V that I fed in the center for approximately a dipole pattern (I sa
