It's been a couple of months since my install, but I started thinking about this when someone mentioned taking another satellite to a tailgate. When I moved into my house (been a couple of years) the old owners left a Dish 500 on the roof and an old receiver that they didn't want (I'm supposing they owned both). I had cable through work, but back in the summer I decided to go with E*. The installers came and said they could take the old dish off the roof but would have to leave the poll that was mounted (no biggie). They left the old dish in the garage and I noticed later on that they took the LNB. It didn't really bother me at the time, but I just started thinking about if I ever do decided to use it at a tailgate or something like that and add the receiver that the old owner's left to my account (have one 622 now). Did the installers take something they shouldn't have?
