No idea what you are trying to do. Are you sending a dish randomly with no coordinates in the sky and trying to do blindscannings? Yes, the Premium Mini and many other boxes will need to pick at least one sat in which you will set your LNB type so you can have accurate TP/SR readings. I guess you can choose anyone based on what you want to do. The best is to try to set your dish to any known sat that you know you can reach (footprint) so you can use that as your reference point.
