I recently moved into a condo with a dish that everyone shares. I was told that I could just go and buy a receiver, which I got one from Best Buy, and just call Directv and have it activated. But when I have tried installing it, I can only get a signal on the odd transponders. Two people from Directv have come out to look at it and they have both ended up telling me that I just need to contact my property mangager and find out who did the original installation of the dish. When I did that, they just told me to call Directv. I am hoping that this is something easy that I can fix, because no one else seems to know how to help me.
