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.
B-Stock Bargain : We have (1) of these boxes available at slightly reduced price. This box does not contain the fitting screws for the "Elite" hardware. It can be supported by the eye-bolts and is otherwise a fully working unit.
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.
Part of our "Elite" range, this features stacked FT240 cores for those running high power or that wish to make use of the optional mast-mounting hardware.
A top-mounted eye-bolt allows for hanging/tying from a pulley, pole or suitable wall-fixing, a side eye-bolt provides strain-relief for the wire and there are 2x M5 bolts on the rear of the box for mounting to our optional pole hardware.
Optional Hardware : A more elegant/secure solution comprises an aluminium plate with a V-bolt. This lets you mount the Coupler on any pole (up to 2-inches diameter).The rear of all our "Elite" boxes have 2x M5 "nyloc" bolts fixed from the inside which screw onto the plate. These fittings are compatible with the outdoor "Elite" series boxes sold by us.
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.
Our standard "250-watt" model also remains available along with a larger 1000-watt model...and, if you'd prefer a "random" end-fed wire matching device, we also produce a 9:1 Unun.
