This was discussed on GQRP a few weeks ago.
I thought I'd check and see if I had all the components to build it.
Well the answer is yes. So I then looked for a small enclosure and found one that I bought from Bowood Electronics (£1.50). The top was metal so I replaced that with the yellow rectangle a piece of FR4 double sided PCB with the copper removed.
I will add a little swtch so that the 10pF between the grounds can be disconnected.
How did the Fuchs Antenna work out? How did it compare with other antenna tuners?
ReplyDeleteThanks.
It worked. It is what it is a long wire type antenna, you need to use the tuner to bring it to resonance the tuning was quite sharp. Which was no different to most similar L match using tiny trimmer capacitors and 270 degree rotation for the full range. Definitely was a case of tune for maximum noise/signal, was not difficult.
ReplyDeleteI no longer have it, sold a while back at GQRP Rishworth rally (probably), but I seem to recall no probably from beach making qso across EU on most bands. I don't think it did too well on 80m but 40m definitely worked well. I used a 10m fishing pole and the wire used to be put up as an inverted L.
I do not normally like anon comments... your name and callsign please?

ReplyDeleteSorry for the anonymous comment and thanks for the information. I'm considering the Fuchs Antenna matching unit from the QrpProject.de for a small 40m radio when I upgrade my license to HF bands.

No problem.
ReplyDeleteYou might do better with a simple 40m dipole or a 40m EFHW and a 10m pole.
