What dish do you have? Is there a single dish pointing for 129? or do you have a dish that points at all 3, 110, 119, and 129?
A single dish for a single sat is fairly easy to re-align even for a owner that's never done one before. A multi-lnb dish can be a real *itch to get just right! If it's a multi, call in and get a pro to do it. It's well worth the money. If you attempt to reaim a multi dish, get ready for many hours of work, learning new words, and for wanting to kick anything around you that gets too close, lol!
