Please help, Im confused. I already have Sky. In a few days I hope to have Sky+ installed. I moved into retirement apartments about two years ago and each complex had satellite box installed. One large sat. dish feeding each flat. I asked Sky three times, and the suppliers of the sky+ box if outside work would be required to dish and cables. All four assured me no external work needed. However, just read the above threads and it appears work needs to be carried out on dish and extra cables. Can you please help, or clarify?
