[QUOTE="RimaNTSS, post: 906879, member: 312276"] Disagree a little, Prodelin refers to distance from[B] [COLOR=#ff0000]FOCAL POINT[/COLOR][/B] of the antenna not PHASE CENTER of the feedhorn, but that does not really matter cuz usually those two points located at the same place (when feedhorn properly placed) :rolleyes:, only then we can get maximum performance of the SAT-system. than could be close to true, however I do not understand why should producer show only half of the angle?! But in case of 50* feedhorn.... I can not imagine antenna with opening angle of 100*! So, I am still puzzled about this. [/QUOTE]
