What is the dimensions of the pan of a superdish?
24 X 34.5 The focal length is way different. As is the F/D and thus "twin lnb" spacing will not work.
Also the focal length of the D1000 is an inch different that the D500. That is a huge difference a these frequencies. As the focal point defines the shape of a parabola, it would seem the dishes have different designs. i.e. F/D ratios.
I'm trying to see your logic in thinking the D500 could outperform the larger D1000.
Guess it's worth a test. You will have to peak the focal point when changing pans. In theory only focal point should need retuning.
