[QUOTE="davemurgtroyd, post: 1092635, member: 319227"] There are two main factors here Firstly whether the "circular" lnb is seeing all of the dish or merely a smaller circle at the centre of the dish - thus giving the effect of a smaller dish (probably the case with a zone 2 dish). Secondly if the lnb is seeing all of the dish then it is also seeing outside the dish and probably picking up noise (from reflections from other satellites from a wall behind the dish etc) so reducing signal quality. Another factor is also mounting the "circular" lnb so that its sensors are at the focal point of the dish - adjustment of this is not easy on Sky dishes. All this is dependant on lnb and siting of dish [/QUOTE]
