I had an RFI problem when I operated 40 meters and took the Radio Shack
clampons and a High pass over to the neighbor's house. We installed them and
ran a test. The interference was gone. I told him he could get all the parts
at RS or he could pay me (which he did) and then I bought the next bath of
RFI fighters. Another way to go.
