I've had success with this unun on my K2/10 and a FT-897 at 100
watts/external tuner. Used a random length of wire tossed up in a tree,
haven't tried to make one resonant.

I am after the schematic or the best guess of the components and parts
placement that will resonate this 40-30-20M antenna. It's not rocket science
but it's close!! As I understand it these antennas are fairly high impedance
wise, so I need some kind of matching network to bring that down to around 50
ohms for the KX2.
Failing that path, has anyone hooked an EFHW to the internal ATU with good
results? I would also include a cut to frequency ground radial that I would lay
out below the antenna. That would be the easiest thing and simple to employ.
