I have a home in Maine and have a cable wire running to the TV in the living room. I would like to now add tv's to the bedrooms but dont want a mess of wires running all over the outside of the house. I went to a home show once and saw a connection box meant for a cellar where the cable wire came in and connected there and if you wanted to run wires to anywhere else, they connected at that box also. The sales person said it was exclusive to their product. Is that true? Are there any boxes like that for regular cable hook up? I would like to be able to change locations of the TV without having torun wires, just plug it into a cable connection on the walls
