Hello all, My friend has a 3 unit house and wants to get off Comcast and go to DirecTv. He wants to install the dish and get his own box, and then tell the renters to contact DirecTv to get their own box. He does not want 3 dish's and wanted to know if it could be done with one. Also, would an installer hooking up another unit in the future have any issue with it? The other units are small and I would not see him ever going over 16 tuners.
