LNB Power and Control:
13V (vertical polarisation)
18V (horizontal polarisation)
22kHz (band selection according to universal LNB for ASTRA satellites)
**input level dependent on function of MODCOD and baudrate
* Maximum supported baud rate is dependent on both tuners active state. One must be disabled to
achieve maximum symbol rate capabilities. View table below for symbol rate capabilities.
