The room we wanted multi-room in was as far as it was possible to be from the dish. The installer wanted to route the cable from the dish all the way around the outside of the house and drill through the wall. He said he couldn't take the shortest route because 'elf n safety prevented him from going into our loft. In the end I fed some string into the loft from the dish location using a long piece of thin dowel and then drilled a small home in the corner of the multi- room. He was then able to pull the cable through tied to the string I'd previously installed. Much neater job.
