I have an old Dish 2700 that I dug out of the garage....looks to be in working order. Looks like the dish I have is a Directv dish 18x20....1000? has three lnbs on it. Can I use the dish network receiver with the direct tv dish? My thought was hey they both use circular lnb's so why not. Any ideas are appreciated. I haven't messed with the small dish stuff in a long time. Thanks Blind.
