Very inexperienced when it comes to running wires, and satellite equip, etc. I have an HR 54 with 2 C61's. When I signed up for my DTV I was given a 3rd C61, so I can have 4 rooms at no extra charge. Therefore I have a spare C61 brand new in the package. So, my question is what do I need to do to run a line outside to my patio? Do I have a powered splitter I would go off of? Just trying to cover all my bases-if I need to get a new splitter for 4 rooms, how much is that, and how much would about 50 ft of coaxial cost? Is it as easy as that? Or am I better off calling DTV and getting them to do it? what would they charge me? Also, my bill shouldn't go up at all if I already have the box and am given the 4th room at no extra charge correct? Thanks for the help guys.
