...has taken a dump! (I think) ...My 7.5 foot Winegard has a C2 on it, that is shared by my DSR-920 and DSR-4200V. (One output to each receiver, no switches) The first one that went out, the output that feeds the 920 stopped working. This time after replacing it with another one, that's been on the dish maybe a year, the 4200 only gets signal when the 920 is on an even channel on G5. (The 4200 stays tuned to a mux on G5 that provides a "Choice" of music) Are these C2's just junk, or is something else happening here? What would make the 920 switch the H/V on the OTHER output? Does anybody know of a better LNBF they're using, that may last longer? I do not want to buy another C2, since they only last about a year!
