EFLW-3K 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 your antenna tuner. For some frequencies, a wide range antenna tuner might be needed.

This is an affordable wire version of a popular 43 feet vertical antenna. Our wires start at 44 feet but a longer length is 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, sailboats, 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 length 44, 60, 73, 88, 107, 140, 173 and 202 feet available
  • Standard #16 AWG XLPE wire with end insulator.
  • Power Handling: 3kW I.C.A.S
  • Stainless Steel hardware
  • Connector: SO-239

Additional information: 

Terminated into 450 Ohms load, VSWR on 9:1 UNUN is almost flat from 1-30Mhz, This is not the SWR of the antenna. This antenna Needs a wide range of TUNER to operate.

  • 9:1 UNUN has very low Insertion loss, from less than 0.1dB at 1.8MHz to 0.2dB at 28MHz, additional loss of whole antenna system could be expected from mismatch on the coaxial cable and Tuner losses 
  • The transformer is wound with PTFE (Teflon wire) on two (2) 2.9-inch diameter Ferrite toroids in order to handle a legal limit of 1500W at any frequency.
  • It takes only moments to deploy the antenna. Pull the wire end into a tree, hang it off the balcony, 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 on your radio.  NOTE: to tune all HF ham bands an external tuner may be required.
  • It could work without radials/counterpoise (Coaxial cable has to be at least 25 feet long) but grounding at wing nut next to the connector is recommended if used close to ground as inverted L configuration.
  • 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 to possible common mode currents on your feeder, we recommend using a CMC-Common Mode Choke/Line isolator such as CMC-154-3K to keep RF away from you and your equipment. It will also help you receive by filtering induced noise from various sources.
