Missing Sky Channels on OS mini

[Oneeyedman]

Hi.
Most of the Sky channels are down on me tonight (movies/sport etc). Other pay channels appear OK (BT, Eurosport etc),which suggests cccam is OK(?) . It's been quite windy and wet here today, but by and large the traditionally weather channels in my area (pavers shoes, inspiration tv) all work and the Snr is at or about 60 percent on the channels that are missing (some @45 percent are OK).
Did a full scan, no change.

Any ideas? Is there a problem with the cccam line for instance after all??

Your description sounds like there is no problem with your line, the dish wouldn't have moved a smidge, would it?

sounds low most should be much higher 92+ even 100% get dish checked i think

Thanks for the replies.
Might be the dish alright, but it has been OK until now (might have shifted alright). The signal strength is over 90, pretty similar to the readings for the terrestrial signal really. I understood the SNR was more important (?), some channels are working with low SNR of 45%. Are the sky channels very susceptible to dropping out?
