[QUOTE="moonbase, post: 986906, member: 178786"] Yes, I agree, for Ku and Ka with the Precision dishes you are pretty much guaranteed to be on an accurate focus by virtue of the feed and dish location points for the three support arms. If you use the support arms and feed matched to the dish then its automatic unless something is distorted. For C Band with Precision/Elite prime focus dishes there is some scope for varying the LNB aperture distance from the dish. However, this is dependent on the type of C Band feed/scalar arrangement being used. The Viking SatCom (ADL) C Band feed arrangement used by Elite Antennas allows movement of both the feed barrel and the scalar so some tweaking is required to get an accurate focal point. [/QUOTE]
