[RFI] Topband: 160m & 80m RFI issues requesting ideas for ANC4 sense antenna to cancell out local noise

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 sense
antenna I just built. That is why I think I am able to null the loop
easily but not the vertical using the hamstick sense antenna.
For what its worth, I never was able to null the signal on any of my
antennas until I did the trial hamstick yesterday. It was my last attempt
and now that I can null the loop I know its possible but it’s the equal

To combat the noise I have been trying to use my ANC4 and I built a
sense antenna out
Connect the horizontal loop and the trapped dipole to the noise
canceller, using one of them as the sense antenna.
