how about compatibility between the two lnb's? there's a dc voltage fed up the coax to the low noise broadband amplifiers at the dish and an rf signal that comes back down the same coax, each to its own receiver at a different frequency. The local oscillator frequency is constant for both signals - 10.7 for fm transmission.
