I have an 85 cm dish and have used it at the two sites mentioned by Allen - but only on Astra 1, not Astra 2. The general opinion at La Manga seems to be that whilst it is not impossible to get Astra 2 on this size dish, it is very critical and requires a lot of expertise. Most people who watch British TV via Astra 2 use a satellite of about two metres in diameter. You can, of course, get some English speaking stations on Astra 1 (such as Sky news), but non of the popular entertainment ones.
