A: The Satellite Diplexer: A Seamless Solution! Satellite programming may not offer local network or independent TV channels in your particular area. Fact of the matter, there is a large portion of rural America that is not covered. The solution is actually quite simple: capture those signals with either an off-air (uhf/vhf) antenna or cable TV feed and add them to your channel line-up.
You can run two lines: one line from your satellite dish and the other line from your local channel source OR you can use two signal diplexers and run both signals down ONE coaxial cable line SIMULTANEOUSLY (Diagram 1). One diplexer is used outside to combine the two separate signals (one signal from the satellite dish and another signal from either an off-air TV antenna or cable TV feed). A second diplexer is used inside to separate the combined signals before they enter your satellite receiver (Diagram 3). Satellite diplexers eliminate the need for extra wiring thereby reducing the cost of labor and installation materials necessary to run two coaxial lines.
