I have a cable wall plate that is installed in my upstairs bedroom that goes down the side of the house outside to the plastic cable box that has a 2-way splitter (one for tv and one for internet) I am disabling cable tv and would like to know if I had the antenna upstairs I could connect a small cable to the wall plate, I install a female pass thru cable to the cable that runs into my downstairs living room that also comes from outside. Then connect a small coax cable to the back of my 6000 from the wall plate in the living room. Does it need to be RG-6 to view OTA HD? I would assume cable wiring is RG-59? My other problem is the box on the outside of the house is locked, but it only has a splitter in there there is no way for them to say I could steal service cause they make changes on the pole with the filters. Can I call them and say to unlock it?
