HI Rick

I have tried this idea also but again not enough gain on those antennas.
The vertical has s9 noise the others are 1/2 that level same as the

KD8NNU

If you are OK with vertical polarization, the simplest way to
null a particular direction is just to use a conventional
receiving loop and rotate it until you minimize the noise.
(This is a loop in the vertical plane, unlike your 2 wavelength
horizontal loop "skywire").  This is a lot more foolproof
than the ANC box.
