1. a satellite-signal treatment facility, it has the first operator scheme and the second operator scheme, and this satellite-signal treatment facility comprises:

  • Low noise block inverter power supply (38), for giving the power supply of low noise block converter in the first operator scheme;

    DiSEqC encoder (39), for generating the control tone needing with low noise block converter signal post in the first operator scheme;

    Transceiver (37), is connected with protective circuit, and for receiving and signal transmission;

    Protective circuit (35) for transmitting without distortion desired signal, protects described satellite-signal treatment facility to avoid the electrical interference of lightning surge and other environment simultaneously;

    AndSwitch block (33);

    for generating during described the second operator scheme for the high impedance with described protective circuit isolation by described low noise block inverter power supply (38); and

    for generate the Low ESR for described low noise block inverter power supply (38) being couple to described protective circuit during described the first operator schemeWherein, during described the first operator scheme, described DiSEqC encoder (39) provides Low ESR output by described low noise block inverter power supply (38) to described switch block (33).
