Cable clutter is a common annoyance with digital television. Many people install both a TV antenna and a satellite dish to get the maximum number of channels. You can save time on installation and cut down on untidy cables with a diplexer that combines both signals in one coaxial cable and feeds them to a second diplexer behind your satellite TV receiver. Use a 2-way splitter for over-the-air and satellite signals when splitting signals to multiple TVs in your home.
