I,ve just had a second digi box installed. My original single LNB was a good quality Grundig type. The new one that was installed by a local installer (twin LNB) looks much cheaper. I asked the installer for my Grundig LNB back seeing as it was presumably my property (just in case the new one goes down the pan), but they said it was not my property but it belongs to sky. Originally the dish and box were purchased outright. I reckon its just a way of them getting free LNB units and re using them. What do you think?
