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.
