How can we work our upstairs TV when the aerial is so crap? Or can we get cheaper Sky?

As you've got sky plus they no doubt put a 4 output LNB on the dish so you should have 2 spare . One could go to a freesat box , or a second hand Digi box in your bedroom. Non HD freesat �50 Humax HD around �130 . You just need some Cable and two F connectors Oh and a ladder............
