Dish size is everything.
Dish size is everything. LNBs only have a very very very very .... small effect as does receiver
sensitivity. Dish size is everything! Going from a 0.9dB to a 0.1dB does not have the effect of
5mm of dish diameter! and then the lower noise LNB will only help in good weather, virtually no
effect in bad weather. Bigger dishes provide more signal in all weathers. BUT .. if the dish size
cannot be increased for any reason, the lower noise LNB can help a small amount and it MIGHT be
just enough to pull in a difficult to receive channel that was just coming in but maybe pixilation or
freezing (a common fault caused usually by lack of signal) was a problem and may be stopped.
0.1dB LNBs! To achieve 0.1dBs over a significant frequency range, manufacturers would need super
cooling to slow the electrons down! Simply not possible at normal temperatures in the UK. It may
well be the case that the new 0.1dB LNBs have the lowest noise figures. They are very good LNBs.
