We live in a large 200+ unit condo. There is a local company that provides the direct tv box and local channels for a fee if you want to have direct tv. If you don't want direct tv you dont' need a box and don't need to pay anything. So, my questions is, if I go and buy my own direct tv box do I need to even use this local company anymore, or since they are contracted for our building to set up direct tv for people who want it I have to go through them. I believe that there is one dish on the roof for everybody meaning that we only need the box to convert the signal.
