[QUOTE="beavs2112, post: 943068, member: 384689"] I prefer a dual cband feed feedhorn with 2 lnbs. The reason is my dish is 6 feet above my roof. The chaparral polarotor requires wiring to control the polarity motor and if that fails its a PITA to fix. many years ago the polarotor was the only option. but if the polarity motor or one of its wiring connections fails you might get only one polarity or worse none at all. a dual cband feedhorn requires no such wiring. The dual cband is more expensive since you need another lnb & rg6 cable but its more reliable. As far as the c and ku band losses I think it varies depending on who you talk to. some people swear by the polarotor, some people swear by the lnbf, some people swear by the orthomode feedhorns. Also another factor that is very important that often gets overlooked is matching the feedhorn to the dish. I prefer to use the feedhorn that the manufacturer of the dish specifies to use. [/QUOTE]
