EFHW-7510-2K-Plus, 2000W Multi-Band End Fed Half Wave Antenna

Improved version of the EFHW-7510-2K, now with three large cores, 2.9-inch diameter, featuring just 0.5 dB Insertion loss 3-30MHz!

This is an End-Fed Half-Wave (EFHW*) antenna for 75/40/30/20/17/15/12 and 10m bands. Unlike many END FED antennas on the market, this one does not require the Antenna Tuner to operate.   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, inverted V, inverted L, etc. are possible.  Your VSWR values could vary with different wire configurations and the height of installation.

  • NO TUNER needed!
  • NO counterpoise needed! (Grounding recommended*)
  • Frequency coverage: 3.5-30MHz
  • Resonant on 75/40/30/20/17/15/12/10m
  • Wire length ~130 feet
  • Power Handling: 2kW I.C.A.S
  • 350W digital modes continuous (FT8, RTTY, etc)
  • Stainless Steel hardware
  • Stealth #14 AWG XLPE black wire
  • Connector: Silver/Teflon SO-239
  • The 2K-Plus model has three large stacked cores

*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 finally got the new wire in the air today. Minimum of tuning with it
    in a slope position from 10′ to 39′! All I can say is WOW, this
    antenna simply works and works well. Great job folks. A little
    expensive, but well worth the extra money… It tunes with the
    internal tuner on my Yaesu FTDX-1200 all the way from 80-10! My
    homebrew antennas worked ok, but this thing is far better…

    I’ve had my 7510 up now for two and a bit years strung between two trees about 25ft at one end and 60ft at the other on the top of a small ridge.
    I live in a very windy location and we get lots of snow and icing and the antenna hasn’t suffered a nick even after the 1/4″ aerial rope snapped due to insufficient slack, over 100lbs pull for sure. The wire, balun etc took the strain no prob. well built. Matches so well on every design band that i dont even need a tuner and my ss amp doesn’t trip. Wire and components are no worse for wear and show no signs of breakdown after two years. This is a great antenna and its ease of throwing up due to its end fed design make for a super quick install. Performs much better than my g5rv and easier to deploy. I recommend this antenna for fixed or portable.
    ps i also have an 8010 at my other qth up for 5’ish years still running like the day i hung it. Reliable well built units.

    First class Outstanding NVIS.
    My feed point end is about 15 feet high in the far end there’s about 25 feet high in a tree. Even when only using 20 watts on my Xiegu G90 Radio many people think I am using an amplifier because I am so loud and clear. But I am not, it it’s just I have a great antenna now.
    I am getting NVIS on 75 m In the evening with crystal clear contacts on NVIS as if they were sitting in the same room with me talking at all distances from my doorstep to about 400 miles in all directions. The 40 works in the day and they both work well at night for NVIS properties.
    For NVIS this antenna for me is just a dream it is fantastic it is great I cannot say enough good about it.

    just got my 75-10 works so good VSWR is perfect thinking of getting another one to run at another direction, i give it 5 stars , great work

    I installed 35′ of LMR400 UG from the shack to a galvanized intermediate fence post with a cap. Then I mounted the EFHW-7510-2K-Plus transformer at the top of the post and ran the EFHW-7510-2K-Plus antenna wire vertically about 25′ above the transformer to a robust tree, and horizontally the remainder of the wire length to another robust tree. I was careful to keep the wire insulated, high, and away from all objects. After grounding the transformer at the post, I grounded the shield of the cable at the cable entrance, and installed a lightning protector and a homebrew CMC at the shack. I put my antenna analyzer on the antenna and I must say I am very pleased with the result. Out of the box, all SWR’s are very acceptable across all of the bands advertised. This antenna is an excellent design and of great quality!
