However if the dish is off by even a modest amount, it will be receiving a reduced signal even in good weather. You probably won't notice that - until it rains, and your already-compromised signal is reduced to almost nothing.

The dish may not have been properly aligned to start with, or it may have shifted if it's particularly exposed to wind, or are there perhaps trees nearby that have grown up and begun to get in the way?

You need the services of a competent, independent aerial installer.

There's no trees in the way, no. There's an unobstructed view of the sky. ..i do live on the coast though. And it gets pretty windy here sometimes. So i guess the mini-dish could be prone to being moved.. I don't think it's wire degradation or anything like that. The set up is less than a year old, and seems in pretty good condition.
Something i've just thought of though, does the number of feeds coming of one dish make a difference to picture quality? Downstairs i've got two feeds going into a humax freesat+ box, and another feed going upstairs to a sky digibox. Would splitting the signal 3 ways like that reduce the picture quality, or does that not make a difference?

Remember as well that the further north you go the weaker the signal is. If suffering from signal attenuation due to rain (rain drops of particular sizes can block a 10Ghz sat signal) then the only way of improving that is to raise the signal level. Which means a lower noise/higher gain LNB and also a larger dish. Proper alignment might help but some areas are known for local weather that will constantly drop out the signal.

I remember during Sky's analogue days that they used to recommend an 80cm dish (over the usual 60Cm dishes) for anyone above a certain latitude. The digital dishes are also now even smaller.. Looking though at the footprint charts they do say 95% of UK mainland can get astra2 on a 50cm dish, these though are ideal scenarios ;)

First thing I noticed when we went south to visit family the other week was that all the dishes are smaller. I hadn't even realised, of course, because round here everyone has the same size dish ... but our dishes are all bigger than yours. :D
