If the OP wants HD then only One Dish will be needed, the Eastern Arc Dish, as Dish currently has the Albany Locals In HD on the 61.5 satellites. The rest of the SD core channels are on either 72.7 and 77 degree satellites. If he wants SD and HD and will not accept 2 HD receivers then he will require two Dish's one pointed at 119/110 and one pointed at 61.5. Although Dish does not currently carry the CBS affiliate in HD, but if you want the SD feed of the Albany CBS affiliate you will require two dishes.
You do realize that for most subscribers on the East Coast (especially Albany, NY) a single Eastern Arc Dish is all that is required for HD subscribers, but you must install ALL MPEG4 receivers to Eastern Arc installation.
