The following fields can be edited on the Edit LNB Attributes page:
Edit Field Description
Frequency Reversal Enables or disables LNB frequency reversal. Off is the default.
Frequency reversal permits the use of other LNB variants that may use low side Local
Oscillators (LOs) instead of high side LOs. The use of LNBs such as older C-Band type with
low side LOs can cause spectral inversion and this feature can make the LNB appear “normal”
when setting the L-Band frequency of the DVB Carrier using the Carrier Edit <X> page.
