We spend our lives (or most of them) trying to give our customers the best picture possible. We connect VCRs & Sat receivers using s-video, and DVD players and HD receivers with component video, often with thick, expensive cables to try and get that last "edge" of perfection. We'll even sometimes forego the receiver's on-screen display in order to connect video directly to the monitor in order to eliminate the loss associated with an extra connection.

And all this is just over the last 10 feet.

Our cable signal comes from miles away, all (x)-hundred channels & interactive services, down a single coax that's tapped at every house on the street, and then split (x)-times in the house. Satellite travels WIRELESS from earth all the way to orbit & then back again to the dish, where the LNB sends it down a single coax to the receiver, usually with a switch on the line somewhere.

If all this is possible, why on earth can't the last 10 feet (that carries only ONE channel) also be a single coax?
