[QUOTE="RimaNTSS, post: 1072081, member: 312276"] [USER=389502]@Phoenixx[/USER] Wow! So much information! Why do you think that opening angle of the main mirror of Fibo 120 dish is 77*? According to mine measurements it is 86*, so Patriot feedhorn should perfectly illuminate the dish. But main idea of dual-reflector antenna-system is to use subreflector and that helps reception.
