I have an old Sky dish first used about 1992. It last worked in about 2002 then I un-subscribed from Sky. Next time I tried it (without Sky subscription but with a card) I think it only gave a very few channels and I think there became less (but that might be flaw in my memory!). I have connected the dish to a Samsung S7800 Freesat box and I get a few channels only (Channel 5 at present, but I think there were a few other channels when I first plugged it in). Do I simply have to adjust the line up of the dish to another satellite? Or is the dish not suitable now. Or is there another reason? Thanks.
