I agree on the dish completely - when I had a BBQ (non) dish there
was some noise until I covered it with screen, then it mostly went
away. Even then, it was perhaps S-1 above the noise level, not
anywhere near the S-3 I experience on 70cm and the S-6 I experience
on 2M. With AO-51 I use a 2.4G yagi, and have never had any noise
problems with it either.
Perhaps I've missed something but has the Eagle team published any
empirical data on the subject?
