LOW NOISE BLOCK DOWN CONVERTER
• xhe receiver uses Low Noise Block Down Converters (C or Ku-Band LNB) for its microwave interface. The output frequency
range is 950 to 1450MH2. Power is supplied to the LNB via its output F connector.
Note:
The receiver is capable of supplying 18 V DC at 300 milliamps max from the input F connector.
• This is sufficient for one LNB and one Line Amplifier. The breakdown is shown below.
Line Amp (+20 dB) 100 milliamps max
LNB 200 milliamps max
If the line amp used only 25 milliamps, then four line amps can be used.
