I live north of Dundee in Scotland and we have a 55x60cm Sky dish at the moment. Whenever it rains or is cloudy/foggy the signal can pixellate and we get failed recordings etc. Even when the system was first installed the signal strength was no more than 50% for both signal feeds. I was wondering if there were any issues I should look at before considering getting a larger dish? Presumably I can just buy a larger 80 or 90cm dish with a quad LNB and replace the present dish. Does nyone know of any quality dishes/suppliers etc that I could buy from? Any help is greatly appreciated, Thanks, Jon.
