EFHW-4010 Multi-Band End Fed Half Wave Antenna

This is an End-Fed Half-Wave (EFHW*) antenna for 40/20/15 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 40m (7MHz) therefore also resonant on second, third and fourth harmonics, 20m (14MHz),  15m (21MHz) and 10m (28MHz). The antenna could be used with 100W on WARC bands too, where measured VSWR is less than 4:1.  Due 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.

Various installations such as horizontal, vertical, as inverted V, as inverted L, zigzag etc. are possible. Measured VSWRs in the gallery are taken with an 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.

  • NO TUNER needed!
  • NO counterpoise needed! (Grounding recommended)
  • Frequency coverage: 7-30MHz
  • Resonant on 40/20/15/10m
  • Wire length ~63 feet
  •  VSWR on 40/20/15/10m
  • Power Handling: 1kW I.C.A.S
  • Stainless Steel hardware
  • Stealth Marine #18 AWG black wire
  • Connector: Silver/Teflon SO-239

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 (monoband) antenna was introduced to HAMs almost century ago by Josef Fuchs, OE1JF, patented in 1927.

    I installed the EFHW-4010-1k at my portable location in Washington state. Installed the end fed box at the corner of the shack at about 8 ft and did not ground it. Used about 25 ft of RG 8X to the rig. (TenTec Eagle 90 w.) Ran the wire straight out to a tree with a line pulley up to about 50 ft. Amazing performance on 40m and 15m without a tuner. Lots of contacts. Easy antenna to put up and use.

    I had an LNR 40 through 10 meter end fed tuner and I liked the antenna, but it was a bear to tune. After reading the reviews on the 4010 I thought I would give it a try. No tuning was required-the SWR’s for 40, 20, 15 and 10 were excellent. But, I am a CW operator and I love to tinker with antennas so I added about 4 inches of wire to the end and the SWR’s were even better.

    But, who cares whether you have a SWR of 1.4 or 1.2 right? The key question is does the antenna work and believe me it does. I have made numerous contacts all over the US and DX and I consistently get good reports. Running less than 40 watts the antenna does a great job. Is it a beam of-course not, but this is a simple very effective antenna which has worked great for me.

    My set up is the matchbox is at 30 feet and the antenna slopes down to 16 feet. I live in a very tough environment (the Jersey shore) where it is windy-average wind speed 20 MP, and everything is affected by the salt air and this antenna seems well made to handle this tough environment.

    Bottom line would I buy another one you bet I would.

    Just received the antenna, installed it on a bamboo pole on the second floor roof top around 35 feet height ground level. Did the initial runs using low-power and soon found out that my LDG AT1000pro tuner has no work to do. My shack set up is Icom IC756pro3/ Tokyo Hypower 1.2kfx/ and I can get 750 watts out put on all the specified bands. We have a late night 80 mtr net running here and with the help of the internal tuner in the rig I can check into that also with out any problem. My first DX contact was ER4DX OM Vasilov from Moldova with a 5/9 report from my qth in Chennai South India, which considering the present band conditions is a good one. Thanks Danny for the wonderful antenna that is just plug and play and has no hassles of tuning, cutting and pruning. I recommend this antenna to all hams whether they are experiences or newbies.

    I wanted something easy to setup and I knew I wanted a EF wire to use with my Kenwood TS-570D. I didn’t want a vertical to take up my backyard. A local ham highly recommend this antenna and I mounted it on a TV mast with the box at 33′ sloped to 16′ across my yard. The 20 meter S8 noise floor I’ve had forever, disappeared and my SWRs were 1:1.8 to flat across all four bands. I highly recommend this antenna, if your looking for a high quality, as advertised, End Fed antenna.

    My EFHW-4010 1KW worked as advertised. Good swr on all bands, low noise, great reception, and was I was easily heard by others. I use a Yaesu FTdx-3000 and a AL-811 at 500 watts.
    However my operating practices caused the xfmr to overheat resulting in swr to increase to unacceptable levels. I do net control duties on 40 meters (SSB) several times a week. In addition to that several net members remotely transmit using my radio via RemoteHams client. This results in lots of transmission time relative to receive time.
    I ordered a second EFHW 40-10 with the MEF-330-2k transformer and problem solved. I’ve seen no evidence overheating during daily net operation this past week. Thanks Danny!

    Just erected the EFHW 4010 Antenna, and by heck it does all it says on the box, mainly i use it on 40 Mts as it just fits in the garden, it works far better than my 66 Ft wire i had up before, Can hear and work stations i am certain i could not hear before, and conditions are still at the bottom of the cycle, it does also work on the other bands. Yes if need to i would buy again, it is well made and will stand the winds we get in the UK. SWR is 1.4 on all bands with out the tuner, but will admit i have a tuner installed all the time. Can work all day at 400 Watts, that is what we are allowed in the UK. Have tried it at 900 Watts into my dummy load with no trouble.
    If you are thinking of buying one you will be happy, just like i am.

    Been a ham for the past 5 years and needed a quick solution to give me some higher bands – lost my mast and TA 31Jr Dipole in an ice storm in early Spring last year. I have compared the 4010 to 40m performance on my Alpha Delta 40/80 hung at 45′ as well as my Butternut HF2V vertical (with 50 radials). It is surprisingly quiet and has a very good S/N. This one is strung North-South – ordering another to string E-W and replace my Alpha Delta.

    I purchased this antenna a year ago and am very pleased with the great results. Have been able to work the world using my IC7300 at 100w with one end up just 20 feet and the other attached to the house at just 12 feet from the ground. Simple to install and really works great. Purchased a second one to set up temporary between two trees when I am wintering in Florida. It was only up about 15 feet but did very well.

    I live in a townhouse community with antenna restrictions. Since 2010, I’ve been very successfully operating QRP with a doublet in my RF friendly attic managed by an SGC autocoupler. No complaints BUT I’ve wondered how an outside antenna would compare.

    I received permission last month to install a low profile wire antenna outside. My home is two stories with both and upper and lower rear decks and there is a 30 foot high pine tree about 40 feet away. This was a perfect setup for an Inverted “L” antenna.

    I chose the 63′ long EFHW-4010 and ran it from the tree top to a fiberglass pole on the upper deck and then sloped it down to the matchbox mounted on the lower deck.

    Clearly, I had a “Perverted” L instead of a standard geometry “L”.

    The darn thing works just great! Resonance is right where it should be and I’ve been receiving consistently good reports in spite of the poor HF conditions. Getting the antenna out and away from the house really does make a difference. I’m a happy camper.

    At first I was picking up more noise than the attic antenna but a Mix 31 2.5 inch toroid with 10 turns of coax through it and mounted NOT at the matchbox but right before the transceiver took care of the noise problem.

    The only further change I am going to make is to replace the #18 insulated wire with Wireman 534 #28. I already called the MyAntennas company and was told this would be no problem. My reason for doing this is to further lower visibility. My plan is to just replace the original wire from the end insulator back to about a foot from the coil. I’ll just cut and solder.

    In summary, operating under present “poorer” conditions, I’m hearing more stations and hearing them with a lower noise level. On transmit I am getting very good reports for my QRP station. This antenna is a clear winner for my situation. I’m good on 40 through 10 and use my K2 internal ATU where the antenna is not resonant.

    WOW is all I can say. Compromised installation, center support is
    10’metal pole + 5 Ft pvc on top 15′ total with both ends 3′ above
    metal roof. After tuning on 7.1mhz (had to remove 1.2′ from insulator
    end) SWR_2:1 all bands, first contact Austria OE3UKW. MUCH quieter
    than fan dipole and works!
    Thanks for a great product.

    My club has used the EFHW antenna a couple dozen times at our monthly HF events, mini-Field Day operations. If trees are available, we string the end of the antenna into one using fishing pole and nylon twine. If no trees are usable, we use a 40 ft fiberglass pole to support the antenna wire. We have made as many as 250 QSOs in a few hour’s operation. Easy, simple, and effective. We love this antenna.

    I mounted this antenna on the chimney of my house. The other end slopes downward to a pole I installed. Since my back yard is not large I had to make the wire turn 90 degrees for the last 8 feet. I’m very pleased with how it works. From Calgary Alberta I make many contacts to the east coast of the USA and also to California. I have also contacted Cuba. I use 40 watts on PSK31. A very good product!
