EFLW-1K End Fed Long Wire Antenna

This is an End Fed Long Wire wire antenna that will cover all bands from 160 to 6 meters, including the WARC Bands, as well as 60 meters and MARS frequencies. It utilizes a 9:1 UNUN transformer in order to bring the impedance of the antenna to more manageable values for you antenna tuner. For some frequencies, a wide range antenna tuner might be needed.

This is an affordable wire version of popular 43 feet vertical antenna. Our wires start at 44 feet but longer lengths are recommended for coverage of 80m or even 160m band. It all depends on of available room you have to install this antenna.

It is a great antenna for HAM radio operators living in HOA controlled housing, hams desiring a very stealthy RV antenna, Field Day operations, sail boats, portable operating, attic and backyard installations, ARES and RACES, etc.

  • Frequency coverage: 1.8-54MHz
  • Non-Resonant on any amateur radio band, TUNER is needed.
  • Wire lengths 44, 53, 73, 88 or 117 feet available
  • Stranded Marine #18 AWG wire with end insulator.
  • Power Handling: 1kW I.C.A.S
  • Stainless Steel hardware
  • Connector: PTFE SO-239

Additional information: 

Terminated into 450 Ohms load, VSWR on 9:1 UNUN is almost flat from 1-30Mhz ( see the measured diagram in gallery)

  • 9:1 UNUN has very low Insertion loss, from less than 0.1dB at 1.8MHz to 0.25dB at 28MHz, additional loss of whole antenna system could be expected from mismatch on coaxial cable and Tuner losses (see the diagram at gallery of S21 measurement of two back to back 9:1 UNUNs)
  • The transformer is wound with PTFE (Teflon wire) on 2.4-inch diameter Ferrite toroid in order to handle 1kW at any frequency.
  • It takes only moments to deploy the antenna. Pull the wire end into a tree, hang it off the balcony, lay it on the roof, hook it to a pole, hook it to a building and you are on the air making contacts.
  • Most HF ham bands can be tuned by the tuner in your radio.  NOTE: to tune all HF ham bands an external tuner may be required.
  • It could work without counterpoise (Coaxial cable has to be at least 25feet long) but grounding at wing nut next to connector is recommended.
  • This antenna can be hung in many different configurations. It can be hung as a sloper, an inverted L, hung in a straight line, zigzagged, vertical, horizontal, etc.
  • Antenna polarization is determined by your installation. Vertical, horizontal, or both can be accomplished.
  • Due possible common mode currents on your feeder we recommend using CMC-Common Mode Choke/Line isolator such as CMC-330-1K to keep RF away from you and your equipment. It will also help you on receive by filtering induced noise from various sources.

    JUST A NOTE ABOUT YOUR 44FT ENDFED ANT. I JUST INSTALLED IT. I LIVE IN A HOA HOUSING VILLA. ((( no ant ))).
    BULL, I’VE HAD 2 ANT’S FOR OVER 5YRS. 1 IS A ALL BAND ANT. LAYING ON TOP OF THE ROOF LINE. THE OTHER IS MY RAIN GUTTERS. I INSATLLED UR 44FT. ENDFED ON THE ROOF IN AN INVERTED V ACROSS THE PEAK OF THE ROOF LINE RUNNING EAST-WEST. SO FAR IT HAS OUT PREFORMED BOTH MY OTHER ANT’S ON BOTH RF OUT SIG. AND ON RECEIVE. ALMOST 2.5 S UNTS BETTER.
    LIKE I SAID JUST WANTED U TO KNOW HOW IT’S WORKING OUT

    I have had the 44ft. end fed 80-6 for about two years now and I have made a lot of contacts with it. I run 800 watts through it and have no problems get heard, I have also tried it with just 100 watts and my signal has drop just a couple “s” units to my contact. It is up about 30 ft. in an inverted “V” going north and south and I still make great contacts to Italy and Japan. So if your looking for a antenna and you don’t have a lot of space get the EFLW-1K you’ll be glad yo did.

    80-10 wire Off Center Feed works very well. Works better than big name verticals I’ve had. You will need a good antenna analyzer if time is short
    . I have several including a Seeed Sark 110 designed by EA4FRB. Computer-aided SWR: trimming was very speedy, I got some down to ~ 1.00, Others not quite so good. But all very useable with a tuner after trimming.

    Hears and works well when I mounted it as an inverted vee with the supplied antenna impedance box at 7 feet, midpoint at 30 feet on a fiberglass pole, other end at 5 feet. Trimming can be exhaustive due to the optimization problem pretty much universal in multiple band wire antennas.
    The goal is to trim the single antenna so all points of minimal and acceptable SWR lie in each band you are authorized to use. Some trimmed lengths have low SWR values in most bands. All combinations of partially or fully acceptable bands are possible. Your task is
    to favor what you can. Perfection is probably not in the cards. But very acceptable SWRs are usually fairly easy to attain with a scanning
    analyzer.

    Pure enjoyment for 13 months at up to 600 watts. Sometimes under 20 watts.

    I have used the EFHW with great success but the HOA watchers (one bad neighbor) made me take it down. So I put up the EFLW 1K with 53 feet of black stealthy wire (supplied) by throwing it over a 35 foot tall tree in a upside down J configuration. The 9 to 1 unun is hidden in my mulch around my deck and grounded to a 27 wire fan radial field hidden under my grass in my back yard. The wire goes up without touching ground but does touch a lot of leaves and tree branches. I have been having great success without stirring up any trouble so far. AndyT KC3GHK

    Tunes everything easily with external tuner with exception of 160 meters but I’ll work on it some more.

    I just put up the 53 foot EFLW-1K on 29 Sept 2017 and it works very well indeed. I tore down my old HB high band vertical and my low band INV L wire before installing the new ANT sloping at 6 feet on the south (fed) end and up 24 feet on the north end. I connected the GND terminal to a GND rod and attached a 15 ft and a 20 ft radial to the rod. The 15 ft radial lies on the ground parallel to and about 5 feet below the coax feeder. With the CMC 330-1K choke on the floor where the 23 foot coax enters the shack I have no RFI at all. I could not compare the old and new antennas, but my log sheets show that my regular digital mode radio pals say I am as strong or stronger all the time. Ditto my reception of their signals. Glad I bought the antenna after reading many positive reviews of MyAntennas products. I highly recommend it to others. Jerry KD0CA

    Bought the 53 foot version earlier this year, band conditions are bad but easily made Canada. Recently I figured out a way to fit a longer wire in my yard, contacted to get a price for the wire only, they just sent it to me no charge. Looking to maybe try a OCF Dipole, if I do I know where I am going to buy it.
