Thinking of getting my Aunt a freeview box for her birthday because she can't get channel 5. Problem is I have no idea how new her aerial is? She lives in a flat so I'm not sure which aerial is hers or indeed if they all share the same one. I suppose I could try it and then take it back if it didn't work. If this is my only option can anyone recommend an accommodating retailer and appropriate freeview box?
