The last few days I have had instances of screen freeze etc, and the "strength" meter has been fluctuating. As I have only recently installed a 60cm dish and good dual LNB, I'm hoping it is not an early life failure of the LNB. Could it be that in this foggy frosty weather ice forming on the LNB?
The signal strength is more than my old Sky mini dish, I live in the West Midlands by the way.

Did you correctly skew the twin LNB, also did you seal the LNB connectors?

Yes I did seal the connectors. If skewing the LNB means twisting it for Maximun output then yes. The strength and quality were, and still are, higher than with the Sky mini dish.

Yes, signal strength will - obviously - be better than mini dish, since it depends on collecting area.

However, "fluctuating" depends on what you mean! If steady, but seems higher sometimes than others, then that's quite normal, due atmospheric conditons, especially heavy rain.

If it goes up and down while you watch, then that's not normal! Usually due to (moving) trees in signal path, but could be other things.

The critical thing affecting reception is "signal quality", so long as that's maintained it doesn't really matter too much about the strength (due to how the picture is decoded).

I don't think a lnb could start doing this, so it probably isn't that, most possible lnb failure modes would be quite sudden.
