Anyone know of any antenna system that would produce a real good null in

something better than that?

Hi Richard,

That would be useful (the cardioid) if the signal strengths are good
enough to follow the interfering signal down into the null. To put
the interfering signal into the null means degrading the other 10 or
more dB.

Otherwise, look for a yagi with about 30 degrees of beam width (in the
vertical polarization).

Thing is, these stations would be quite weak, so I could do with gain, so
perhaps a good yagi is the way to go after all. .Like you say, rotate until
the offending station goes down in the null of the antenna.

I think also you are saying use vertical polarization, because that
orientation always produces the sharper pattern. I never thought about that.
I was though intending to mount vertically as it happens. Thanks.
