The End-Fed Half-Wave is a popular choice for simple /P operating but can also be used equally well at home. This type of matching device transforms the high impedance of a half-wavelength wire down to 50-ohms as expected by your transceiver. A ground terminal is also provided should you wish to run a counterpoise.
You can run the wire horizontally (ie: 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.
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 an internal ATU. We like CB19917 from CPC for our aerial wire.
If you'd prefer a "random" end-fed wire matching device, we also produce the Multi-Unun which features 4:1, 9:1 and 16:1 ratios.
