I recently switched from cable to sat because of changes in sports coverage. I was amazed at the difference in picture quality of sat vs cable. I am building a new house and chose to have it pre-wired for cable. I now want to switch to sat in the new house. The builder wants to charge me a $500 penalty for making the switch plus $90 per cable to add enough cables for sat. The builder will not let me on the property to add cables myself before the wall board goes in. The cable pre-wire includes one RG-6 going to seven TVs via panel in a closet. I will have a quad LNB, one 522 and one 322. Can anyone suggest how to make the conversion after the walls are in place?
