Hello and welcome to the SatelliteGuys.US FTA forum
I would try to set up your system to an easy to find satellite first as IA-12 is really at the fringe of reception and the dish elevation is so low it will be a problem. You can always come back to this satellite and try again, but I feel you will need a bigger dish and a lower noise LNBF.
Universal 1 is the correct LNBF setting.
