Jim, I use a JPS Communications ANC-4 for noise cancelling on 6M and use a 4el
6M Hy Gain antenna as the noise sensing antenna. It works effectively for me. I
live in an urban environment with lots of noise sources of course. I find the
ANC-4 to be effective on most of them. I have found the key for the ANC-4 to be
effective on 6m is the sense antenna.

Subject: [TowerTalk] Noise Cancelling For 6M
I've got a strong 6M noise source from a solar system at the edge of my
property, about 400 ft from my 6M antenna. I want to put a 3-el Yagi at
it and use it to cancel that noise. Ham noise cancelling hardware that I
know of is all geared to HF.
Over the years, I've heard of CATV operators using this technique to
kill on-channel QRM from distant stations, so I'm thinking there must be
hardware to facilitate that. Anyone know anything about this? Any other
ideas?
Thanks and 73, Jim K9YC
