Ok, I'm wanting to get Sky digital to replace analoge telewest. We currently have 4 outlets and I'm prepared to drop to 2 Sky boxes plus 2 magic eye units. I was told by a Sky operator that a second box would cost £169 but I could try for a second hand one. I've since organised getting a used Sky digibox which should be arriving soon. There was no mention of me needing a 'twin LNB'. I neither know nor care what one of those is but on speaking to Sky again this morning apparrently I need one to have a second box and Sky won't install this unless I pay £169 for the second box from them. I've been misled. Oh bugger. Effing Sky. So what do I do now? Order a standard installation and then get a local supplier to fit a twin LNB and hook up the second box? Will that be expensive?
