In the digital age, a common sight is a satellite dish and antenna occupying the same roof because sometimes satellite providers do not offer local independent stations or local network affiliates. Satellite decoders happily combine the programming information on the same decoder box, but in order for that to happen, the signals must first be combined. Diplexers are signal combiners, designed to take signals from multiple devices, combining them on one cable for convenience and ease of installation. The use of diplexers is an everyday occurrence in nearly all satellite and antenna installations.

Things you need
- 2 2x1 diplexers
- RG-6 coaxial cables (two short, one long enough to reach from attic or basement to back of decoder)
Locate the incoming satellite and antenna cables. These should be in either the attic or the basement.
Screw the antenna cable into the "ANT" input on the diplexer. Connect the satellite lead to the "SAT" input.
Screw an RG-6 coaxial cable onto the "IN/OUT" leg on the diplexer. Route the cable as needed to the rear of the satellite decoder.
Screw the RG-6 coaxial cable into the "IN/OUT" leg on the second diplexer, situated behind the satellite decoder.
Connect a short RG-6 coaxial cable from the "SAT" leg to the "SAT" input on the satellite decoder. Connect an additional coaxial cable from the "ANT" leg to the corresponding input on the decoder.
