Hello. I'd appreciate some advice, I have a Freesat system this has been an issue for many years now, I have a zone 1 sky mini dish. I get pixilated picture on majority of hd channels apart from BBC 1 and 2. And BBC news. S4c hd pixilated all the time and sky mini mix hd. Quest hd. In the rain or heavy cloud it gets worse and lots of channels have issues. I was wondering if this is a widespread issue or my dish at fault. Kind regards

Dylan green: This is obviously not related to Sandy Heath but I used to have a 1 metre dish and lost the signal a few times when huge black clouds were overhead.
Water droplets, especially in clouds hundred, probably thousands of feet thick can completely block satellite signals. If you are confident working at the height of your dish you can check whether the cable connection is well protected from moisture. Also slacken the bolts and make tiny adjustments to the dish position to see if you can improve the signal. Hopefully your receiver has some kind of strength and quality meter display. Failing all that a new LNB may be required as they do get damaged by the Sun especially around the time of the equinoxes. The spring equinox is in a few weeks time!

Unfortunately due to medical issues I can't access my dish, not really in the financial position to pay anyone either, the signal quality is 75% on the worst channels breaking up but on most of them it's 100% yet still get break up.

But it does sound like the signal strength could be marginal for one of the reasons mentioned by Iain Martin. Do you not have a knowledgeable friend who could access your dish?
