What dish are you using? Most online calculators give you the coords for a single LNB dish and you will need to determine your actual coordinates based on the dish type. You said HD, so do you have a PhaseIII or AT9? You can also use a receiver to get the same info.
I'm only using a single lnb pointed at 101 due to line of site issues. I was hoping the ,New?, Directv Sat's for HD might be as high up as 101 or close so I could receive them. The link you gave me seems to only list 3 Directv Sat's still even though I believe the new dish has 5 lnb's?
