How to Connect a Diplexer

by Adrian Grahams

Cable clutter is a common annoyance with digital-television. Many people install both a satellite dish and an “over-the-air” TV antenna 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. Connect this diplexer to your satellite receiver and you can access all available stations through the receiver's electronic program guide.

1

Find the access point for the incoming antenna and satellite cables. This is usually the basement, ground floor or attic.

2

Fit cable connectors to the ends of each cable.

3

Connect the incoming satellite cable to the “SAT” input jack on the diplexer.

4

Connect the incoming TV antenna cable to the “ANT” socket on the diplexer.

5

Attach the connector on one end of the long RG-6 cable to the “IN/OUT” jack on the diplexer.

6

Run the cable to the satellite TV receiver. Use the shortest route and avoid kinks in the cable.

7

Place the second diplexer behind your satellite receiver.

8

Attach the end of the long RG-6 cable to the “IN/OUT” jack on the second diplexer.

9

Connect the first short RG-6 lead from the “SAT” jack on the diplexer to the input socket on the satellite receiver.

10

Connect the other short lead from the “ANT” jack on the diplexer to the correct socket on the satellite receiver.
