The End-Fed Half-Wave (aka: EFHW) is a popular choice for simple /P operating, but it can also be used equally well at home where a single wire down the garden wouldn't attract too much attention.  This type of matching device transforms the high impedance of a half-wavelength wire down to the 50-ohms expected by your transceiver.  A ground terminal is also provided should you wish to add a counterpoise.

You can run the wire horizontally, from the house down the garden or directly up a telescopic fishing pole (eg: /P setup).  This makes it an ideal solution for low-profile use at home where restrictions may apply.

  • Weight: 280g
  • FREE instruction sheet with tips/tricks!

Wire Lengths - we do not sell/supply wire
Approx 21m will be resonant on the 40m, 20m, 15m and 10m bands.  Approx 42m of wire will present a low (under 3:1) SWR on most bands 80m-10m - hopefully bringing it into range of a radio's internal ATU.  You can also add "traps" along the way if you want to get creative with wire lengths.  More details are given in the supplied info sheet.

If you'd prefer a "random" end-fed wire matching device, we also produce a 9:1 Unun.
