Why is it that still to receive C-band signals you need a dish size minimum of 1.5 metres? KU band the dish can be as small as 45cm but 25 to 30 years ago you needed a 1 metre dish to receive Eutelsat II-F1 at 13 degrees east(I managed to get it with a 80cm dish in 1994 but was sparkly on some channels in good weather conditions) so on KU the signal strength has increased and dishes needed have become smaller so why hasn't C band not done the same?
