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 resonant Half wave on 80m (3.5MHz) therefore also resonant on second, third and fourth harmonics etc.  Due to 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 at few feet above ground, your values could vary with way and height of installation.

See it in action at the video bellow…

  • 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 Marine #18 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.
