The lnbf you refer to has multiple ways of setting up. Are you intending on using only the
C Band capabilities? If using both C and Ku are you planning on using the internal
DiSEqC switch? The LO settings should be 5150 for C Band and UNI or 10600 for Ku. If your receiver has the ability to set both LO's for a UNI lnbf it would be set to 9750 for low and 10600 for high. If you are using the internal switch I do not remember which port is C and which is Ku. I use mine only for C Band with the plate installed for circular reception.
