Not sure if this still works because I haven't had DTV in many years. So you may want to check into it first and find out if it is still possible.
You need someone that has DirecTV and gets Sunday Ticket. If you do, tell them you will pay for them to get an extra box and half the cost of the Sunday Ticket. Use that box at your house in NC. You already have the dish. DirecTV's signal doesn't know what dish it is sending the signal to, it is the activated card that allows the signal to work on your box. You just can't plug the box into the phone line.
Again, not sure if the technology has changed but may be worth a try.
