The  Multibandfuchs by DL7AQT, Frank

The FUCHS Antenna got its name from the Austrian Radio Amateur FUCHS, who first decribed it in 1928. It was a monoband endfeed Half wave dipole.

The length of the antenna wir should be a Lambda/2 or a multiple of it. For 3,5 MHz you need abt 41 Meter

With the FUCHS Network it is possible to use an 41Meter wire on all bands between 10 and 80m.


Table 1 shows the length we need for a given number of halfwaves per band






The QRPproject FUCHS Antenna

The network fits into a 70mm x 50mm x 25mm plastic enclosure. A BNC plug plus a BNC to BNC connector gives use the flexibility to use it with any rig which has a BNC antenna jack. Tuning is very easy. The first step is, to find the point of maximum noise / loudest signal in receive. Now with a small transmitter signal, the linkis switched to lowest SWR. Ready. The FUCHS is equipped with an output indikator. Only at the point of resonance, the LED glows.
