Description

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

Improved version of the EFHW-7510-2K, now with three large cores, 3-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 is 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 
  • Transformer MEF-130-2K+ covering 1-30MHz

*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.

    EFHW-7510-2K

    Message:
    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!

  6. Ernie Waite

    Got this antenna up about two weeks ago and loving it! It runs as an east to west sloper, starting at 8 feet and going up to about 20 feet. The automatic tuner in my Yaesu FT-991A brings an already low SWR down to almost nothing. I have been asked several times if I’m running an amp but I am running barefoot. This is an excellent antenna and my XYL is pleased with how stealthy it looks.

  7. Greg K8CGS

    I have owned about every inverted V over EFs for reasons most do. But
    I changed QTH a year ago and needed a quick antenna before winter. A
    friend that has more money in antennas than my QTH said to get your EF
    75-10m. He said he uses it more than his quad. After a year I have to
    say this thing is magic. It is so superior to any wire antenna I have
    operated. So much, I have decided not to put up a Hex. Thanks you all
    and Merry Christmas!

    Erected the 7510-2kPlus EFHW Antenna a week ago at my QTH in Connecticut. The antenna is pointed E to West at 35 to 55 feet high in a flat top configuration (the land slopes down away from the QTH).
    I have the antenna starting about 30 feet away from the house to reduce any domestic QRN. Door springs provide flex near the supports. Dacron runs from the springs to the supplied insulators. LMR400 feeds the antenna at a length of 40 feet. Palstar HF-Auto is the tuner front ending the Palstar LA-1K amplifier and Yaesu FTDX101MP.
    Worked the OMISS QSO SSB Party on 20M with contacts from Italy to Alaska, Hawaii and south to Suriname and about 40 states and many Canadian Provences. Recently, on 10M contacts in Chile, Brazil, Argentina, Jamaica and Belize. On 12M contacts in Italy, Slovenia, Norway, Spain, Portugal, and Russia. Using the antenna I am aware there are some major lobes and then some nulls as well on 10 and 12m. Oddly enough right off the tip (pointing west) Arizona, NM, Utah and Wyoming are 59 SSB contacts much to my surprise. So far I am pretty impressed with this antenna’s performance and the Palstar HF-Auto can get the SWR down to about 1.00 to 1.1 on 40, 20, 15, 12 and 10 in the SSB phone General frequencies. I have not tried the antenna on 75M. This is a real winner of an EFHW antenna as far as I am concerned. 73s and Kudos… Art W1SWL. (Always Listening!)

    Pleased with the antenna; construction, SWRs, performance.

    My installation is o.k., not optimal. 35 feet vertical, then horizontal portion slightly rises. But it’s in close proximity to tree branches and a trunk. 75 feet of LMR 400 to radio room.

    SWRs at radio room, without any tweaking of antenna: 75 m (3.900) – 1.1! 40 – 10 m including WARC bands (except for 30 m) – all less 1.5. 30 m – 2.9. Even 6 m is 2.4.

    Performance – very good for a simple, single wire, multiband antenna. With 90 W or less SSB and with limited operating time and casual pursuit of DX, have worked numerous European, South and Central American stations. Good reports from all over North America. No Asia yet, but can hear them. Even quite a few long distance North American contacts on 6 m (I understand that anything can work on 6 during openings and many were with 6 m big gun stations).

    The 7510 replaced a non-resonant “L” of about the same length in the same location. The non-res used a high quality un:un (from a different vendor), four elevated counterpoises and a remote autotuner at the base. The 7510 gets significantly better signal reports on all bands. No sure why, but it does.

    Thank you Danny!

    I built a tilt pole that is 35 feet that’s the feed point .it’s also the bottom of the property with 12 foot drop from my house. I have a 20 foot pipe next to house with a pvc pipe 6 feet off top of that pole that puts the center of the wire at 40 feet, and it’s hook off a tree with pulley and a weight with my Kenwood 590 or the FT 101dx and 600 watts on 17 meters 20 meters 40 and 75 meters im busting the pile ups like it nothing seriously I have tested dozens of different methods Antennas this one is by far the best in the world personally with this kinda performance and quality it’s priced very good it’s well worth it I have been working stations in Russia, England, Australia Ireland, India and the Dominican republic with 500 watts and a S-15 to 25 over report and even with only 200 watts I’m working every thing I’m working with 500. I ran the R9 it was good ( when it’s tuned right) but the end fed it’s 50-1 better with my MA5B anyone I copied the beam was S10 with some noise the end feed there S7 low noise but I’m hearing stations in 12 states in all directions I give this 7510 a 10 stars rating quality perfection, and performance it’s the best of the best there is none better than the My Antenna. 73”s from Kg4Muk.

    After weeks of fighting with the radials on a vertical to get the
    SWR’s low enough to transmit I decided to try the ESHW-7510-PLUS
    with my Yaesu 101D. Installation was about 1 hour and it’s up about
    40’ and the SWR’s are 1:2 to 1:4 across all bands.
    OUTSTANDING!!!!. My compliments on your engineer design and the
    quality of your product.

    EFHW-7510-2K-plus
    WOW! What an improvement! I had an EFHW-8010 from Myantennas.com and I was very happy with that but it got damaged. It didn’t get much on 20 meters from the start and was limited on 40 meters, I just assumed it was the way I had it installed. Then messing with the trees it was hung in I accidently cut 9 feet off of it; which decreased reception on 40 meters even more and killed 20 meters altogether. It worked fairly well on 80 meters which is the band I spent most of my time on, so I was living with it. You may say that now would be a good time to get into building your own but I have no interest in building my own yet; electronics is sort of like voodoo to me, especially when there are people like Myantennas around who have the electronic knowledge and experience that I don’t have. Decided to see if I could rehang it to get better usefulness but did not help. I saw an update on the myantennas website about this antenna and the improvements that were made. it was substantially more expensive than the one I was replacing but I hoped there was an equal improvement in performance so I went ahead and bought it. I strung it up the same way I had the damaged one and I was very surprised to see the waterfall on my radio (Yaesu FT-DX10) light up! I’ve got stations on my 3 primary interests – 20,40 and 80 – through the entire spread of the bands! All i can say is WOW! this antenna so far (aprox. 4 weeks now) has been worth every penny as well as being better able to take advantage of the quality of the radio. Now I have to see about getting it higher in the air! I live on the side of a hill in a deep valley with lots of cedar trees around so reception is a challenge anyway but now I have a chance at getting some distance!!

    OK. 2 houses . EFHW-7510-2K-Plus installed at one last week checks out perfecto – especially the low SWR at 3.88 MHz is sweet for my 75m AM habit. So what to do? Just entered another order for house 2 to get one of these babies as well!

  14. Kory

    I have one end of the wire about 50-60’ up in a tree sloping down to my garden about 5’ off the ground where I feed the matchbox. Results have been absolutely fantastic! I operate mainly SSB and I can operate on almost all bands with no tuner engaged what so ever. The SWR on 17 and part of 20 is easily cleaned up with the rig’s internal tuner. So far this weekend I’ve worked stations all over the world. Yes band conditions have been good but this antenna is helping as well! It’s fun to be able to hop around essentially all of HF without even tuning most of the time! I’m just running 100 watts right now but a 700w SS amp is probably in the future and it’s good to know this can handle it. I’m going to buy the 40-10 version for POTA activations!
