Well, unlucky you, none of your locals are in HD, that's why it's only SD that you see. Your locals come from 61.5.
You don't need 77. No harm having it but you get no programming from it. You might get better signals if you had the new dish that gets only 61.5 and 72.
Then you would need a dish getting 119, and if you wanted, add 110 to it.
OR
Your locals also come off 119!! (still in SD) You could get all the Western Arc (119/110/129) if you wanted to assuming you can see 129. But if HD locals were to be added, my best guess is it would definitely be added to the Eastern Arc, only maybe to the Western Arc, so it may be better to keep 61.5/72 and then add another dish to get 119. (And 110 if you wanted to) Plus it adds some redundancy.
