I'm moving next week, and my new place is a 21 year old home that currently has cable TV service. The basement is completely finished, and I cannot find a coax junction point (or central location) anywhere. There is one coax line that comes into the home in the basement right at the same location as the electrical panel. So my assumption is that there are probably splitters used throughout the walls and ceilings. I have 4 receivers to install, one in the basement, den, master bedroom, and garage. How will the installer address this? Will they just want to run all the cabling outside the home and through the brick into each room (which I would prefer not to do)? Or is there anything I can do to try and figure out what's going on with the wiring before they show up next Friday (I get possession Tuesday)? Any suggestions appreciated. Thanks.
