[QUOTE="Channel Hopper, post: 1010054, member: 175144"] Feed design is one of the more expensive outlays in satellite technology, many manufacturers simply do not bother and rely on third party companies to provide a solution, which is why Chaparral and others have a range of settings on their products. The scalar ring in these cases has two main functions, to improve illumination of a feed in a system where the feed is not perfectly matched and to provide a stable and accurate fixing point for the feed. You will also deduce from your sketch that; 1) A deeper dish has less need of a scalar system than a shallow dish, and 2) A shallow, prime focus dish is less affected by a scalar ring system, as a result of the smaller shadow created.
