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?

73,

Emily
