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 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 signal problem.

Thanks
Don

HI Guys,

I have an intermittent RFI issue that comes from a subdivision about a 1/4 mile away.
  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.
