I am having Directv installed Monday morning. I have a question about installation: I told them I have two tvs and want wireless Genie. I think my order says I am getting two wireless Genie Minis. I believe there is also a Genie server (or base). Does the Genie Server need to be connected to a tv? Or, does the server just sit in a closet connected to the satellite and to the other box that sends the signal to the wireless Genies?
