Amateur Radio Homebrew Experiments
The antenna length is 41m and the counterpoise 7.5m.
Tunes 80m, 40m, 30m and 20m.
Hi Charlie,A quick question. In the title of this EFHW tuner, it says 80m,40m,30m,20m, but in the handwritten notes, it shows 80m,40m,10m. Which is it please? Hopefully it covers 10m, but I can always make another for the higher bands.73GrahamCT7AXD
Not sure if you saw the last video with the VNA.
Will have a lookThanks.
Hi Graham. The ATU tuned up the 41m antenna and 7.5m counterpoise on 80, 40, 30 and 20m. I fully expect it would tune up 10m with a shorter antenna, as that antenna would present the same Z to the tuner.
Will give it go and see what it can do, and with a shorter aerial for 15m - 10m.73
excelent very easy to follow your design. thanks
I'm pleased you found it useful Felix.
