EFHW-8010-HP 1500W Multi-Band End Fed Half Wave Antenna

This 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. It is a resonant Half wave on 80m (3.5MHz) therefore also resonant on second, third and fourth harmonics etc.  Due to the High Impedance feed point, the antenna is less height dependent. You can put it up at 10 or 50 feet in the air without much change in VSWR values.

*This is perfect antenna for ALE HF-link  stations, NVIS, MARS, ARES, EMCOMM etc.

Various installations such as horizontal, vertical, as inverted V, as inverted L, zigzag etc. are possible. Measured VSWRs in the gallery are taken with the antenna in an inverted V shape with the center of wire at 20 feet and ends a few feet above ground, your values could vary with way and height of installation.

See it in action at the video below…

  • NO TUNER needed!
  • NO counterpoise needed! (Grounding recommended*)
  • Frequency coverage: 3.5-30MHz
  • Resonant on 80/40/30/20/17/15/12/10m
  • Wire length ~130 feet
  • Power Handling: 1.5 kW I.C.A.S
  • Stainless Steel hardware
  • Stealth #18 AWG or #14 AWG black wire
  • Connector: Silver/Teflon SO-239

*Grounding at the transformer box or end of the coaxial cable is recommended for protection of your equipment from an electrostatic buildup in order to prevent ESD- electrostatic discharge.

NOTE: grounding does not affect antenna tuning. If the transformer box is installed high above the ground , there is no need to route the ground wire from the box, instead just ground the coaxial cable at the entrance to your home or at the station.

    I used it with KX3 + expert 1.3k-fa combo. Good SWR requires a balun. Mine was a few loops of coax around a large toroid some 15 ft from the box. Not a problem at a KW level. Worked station at noise level that would be unworkable at 100W. This antenna is an ideal solution for high power where antenna weight is an issue and multi band operation is desired.

    I have the 330-1k running from 10 ft to 45 ft back down to 6 ft…. straight line from east to west.Works well but had a difficult time with the length of the coax, would work on all bands but 80 meters. I was using about 140 ft of coax. Rerouted using about 100 ft and using the tuner it works fine. Using the ground at the transformer box at the feed point. Not the best antenna I have used but allows all band operation with one antenna. But to be fair band conditions are not the best for testing antennas either!

    After using the antenna now for a few weeks I have found that it works quite well. I can work anyone I hear whether dx or local stations. Band conditions have not been good but this antenna works very well!

    I’ve used the EFHW-8010-HP for the past several months and have been super pleased with the results. Operation without a separate tuner is possible on all bands 80-10 meters except for the high end of 80 meter where the VSWR gets a bit too high ~ 7:1. (In fairness, I trimmed my antenna to the lower ends of the 80 and 40 meter bands, so this is not at all a surprising result.) What is surprising, however, is that even tuning at the low end of 40 allows better than 3:1 VSWR across the entire segment. Most other bands have much better than 2:1 VSWR across their entire range. Pretty spectacular!

    My antenna feedpoint is located about 4 feet off the ground, a vertical run of 11 feet places the near end at 15 feet, and the far end is tethered to an oak tree at approximately 40 feet height roughly 120 feet away. The antenna is grounded to an 8′ copper rod driven into the soil at the base of the antenna feed. The antenna is oriented East-West, and interestingly the best propagation appears to also be in the East-West directions. I placed a CMC-130-3K common mode choke at the feedpoint, and this bought me about an S-unit or better in noise reduction.

    I’ve been a ham for 52 years, usually subject to home owner’s restrictions on towers. This is, by far, the best wire antenna that I have used.

    The B E S T wire antenna I have ever had in 50+ years of hamming!!!!
    My highest SWR is 1.8:1 in 18.072 MHz Most bands are 1.2:1. First contact was a JA7 on 7003.28 MHz-RST 579 W/100 Watts.
    Out performs my G5RV hands down!!!
    Buy one. You will not be disappointed!!

    I purchased this antenna back in the spring of 2017, and it has worked well beyond my expectations. Signal reports are consistently good, and I really like that it’s a multi-band antenna. I do use a tuner on 75 Meters to provide the radio a better match at the edges of the band, but the antenna works well with out the tuner. The build quality is top notch, and it’s clear that the antenna is designed to provide years of use.

    Highly recommend!!!

    I recently installed the myantennas EFHW 8010-HP. I arrived at this choice through much trial and tribulation and disapointment. Forced to use trees for support, I needed a antenna what would be easy to string up, and tolerant of less than ideal installation. Seeing the radiation plots for this antenna and reading reviews had me excited. The end fed design I felt would be easier to deploy than say a center fed wire antenna, at least in my case. Before putting up the antenna, I had some questions about installation. Daniel responded immediately with a excellent answer to my questions. I should note, I bought this antenna used, I did not even buy it directly from myantennas, yet, Daniel was super fast to help me. My feed point is 25′ high in a pine tree. From there, the wire slopes up to a height of 50′ in a oak tree. From the apex, it slopes down to about 30′ high at the far end. There is about a 20 degree zig at the apex if viewed from overhead. SWR on 80-15m is about 1.3 to 1 On 10M it is about 2:1 to 2.3 to 1. I currently have about 150′ of RG-213 equivalent coax from Wireman. Plenty of low SWR bandwidth on every band. I am not happy with this antenna, I am elated !!!!!!!! Finally not only can I receive extremely well with low noise, I am actually making contacts and not lost in the noise !!!!!!! This antenna truly does everything it is claimed to do. Actually, I think Daniel’s claims are a bit too modest. Getting my ticket back and getting a working station has meant nothing but frustration until I put up this antenna. I learned the hard way,,, antenna makers claims of “works all bands with a tuner”…. yeah, well, the same could be said for a wet piece of rope. If you want a easy to deploy antenna that tolerates less than ideal installations, truly resonates on all bands, that is actually a efficient antenna….. I truly do not think you could make a better choice than the myantennas EFHW 8010-HP. Thank you Daniel for a great product and great support !!!

    This is the best wire antenna I have ever used since being a ham for over 46 years. Low SWR and so easy to set up. My highest SWR dip is 1:5 to 1 on 18.070. You can use this antenna without a tuner. Yes, without a tuner, although I do use one to keep my solid state linear happy. My first day on the air I worked Australia from Virginia with 10 watts using my Elecraft KX3 on my back deck. Once I get the antenna up in the trees a little higher, it will rock!

    I recently purchased the EFHW-80. I wanted to improve my capability on the HF bands. I have a fan inverted L which does a good job on the lower end, (160 &80), but not so much on higher frequencies.
    I heard about this antenna from a fellow ham in the local club, so I thought why not give it a try.
    I mounted it in the back yard, about 15 feet on the low end, and 35 feet at the far end, all in a straight shot. The SWR curves were good on all the HF bands. On 80 I can’t tell a lot of difference from the inverted L and the EFHW.
    I’m happy with the antenna, and would recommend it to others.

    Have this antenna up as an inverted L, the vert portion is abt 32′ with the rest sloping up to abt 45′, I feed it at the bottom of the L and have the matching transformer box attached to a steel plate I welded to a copper plated 8′ ground rod (grind off the copper before you try & weld!) and the ground terminal of the matching Xfmr running to the rod with 6″ of 1″ copper braid. I also ran one 34′ counterpoise wire out under the antenna (because I could). I am feeding it with abt 75′ of RG-8x coax into my brand new IC-7300. Everything in the shack is grounded to a 6′ ground rod driven thru the cellar floor with more 1″ copper braid. The antenna runs NNE to SSW, the vertical is at the NNE end.
    I am truly amazed on how well this antenna, in this configuration works! In abt 3 weeks operation (back on the low bands after 40+ years) I have worked 20 countries in Europe, all over the US & Canada, Brazil, and Australia on 40 meter SSB. Spent abt 30 min on 20 meters with it and worked Italy, Iceland and several US stations yesterday morning.
    I already purchased the 40-10 version to put up at right angles to the 80-10 unit as all I can fit on my yard easily and safely is the shorter one in that direction. If the shorter antenna shows any advantage in that direction I will look closely at putting up the longer one somehow.
    I took some SWR plots with am MFJ antenna analyzer and they were all well within what the built in tuner of the IC-7300 can tune. A dummy load will have a 1:1 SWR which means nothing, radiating and capturing RF is all that matters, the proof is in the QSO’s ……… I am thrilled with this antenna, it is well made and it works for me!
