I am in the process of getting Dish network. I have installed an OTA antenna and thought while I am running cable from the antenna to my tv that I would run the cables for the sat into the house also. The antenna will be connected to a grounding block on the outside and thats the point I would run the cables from to the inside for the sat receiver. Questions are is, will this be fine to the installer? Figure they would love not having to crawl under my house and running wire and I would make sure its done the way I want. I am using RG6Q cable so I think that should be good. Second question, I will have the ViP722k installed and I should be on the Eastern Arc 110/119/129. How many cables need to go from outside to the receiver, 1 or 2?
