Welcome to the forum,
Crast!
Aerial select SINGLE is the best choice right now.
First set LNB Voltage ON.
LNB frequency UNIVERSAL is good, keep it that way!
Then try a satellite scan, all frequencies, or if you have the option of BLIND SCAN do that.
Then please report if you receive any channels.
(Edit: And which ones (examples), and at which frequencies, to check at what satellite the dish is aimed. Which satellite are you after?)
BTW Octo LNBs (with 8 outputs) usually are not the best ones; but hopefully this one is (still) OK.
greetz,
