I guy in my office has an old SuperDish but no LNBs for it. I told him I would help him hook it up to my old 811 so he could get the local OTA HD stations (my understanding is the 811 must see a satellite to be able to tune in the OTA stations). What type of LNB would he need? I'm guessing he would only need to see 110 or 119, or both but not the third sat (118?). Thanks in advance for your help.
