i'm a dish tech, but my next door neighbor is a directv customer. he recently re-did his roof and i offered to re-install his dish, (how nice!). i'm just not too sure how to aim it. He has the slimline dish for his HD. i have a super buddy and theres 3 or 4 different options for the slimline and i just don't know which one to use. or zip code is 55060 and it seems like he's picking up 5 signals. 3 in the center head and 2 to the left. i could take a picture and put it up on here if that helps. any advise would be awesome. thanks.
