Hi I live on the east coast of Engand nr Skegness my Ski digi system has worked fine for 18 months but now looses channels to weather conditions The channels that go include ch4, e4 all MTV and VH1 channels, Nick Jr, CNX, Travel ch, Sky prem4 to name a few. Sky call it adverse weather conditions but it only takes a drizzle of rain to affect these channels. I've checked the wires ect. Its always rainning here on the coast would I be better of getting a larger dish? If so which one? Just a quick point to mention I am surrounded by open fields so there's nothing getting in the way either.
