How to Hook Up Cable Splitters

By Mikhailauna Bulba

Cable splitters are generally used when there is only one line of cable running into a home or business and another connection is needed for a second device within the same building. Cable splitters come in a variety of sizes. Depending on your needs, you can choose anything from a two-way splitter to an eight-way splitter. These devices are easy to install and only take a few minutes to actually connect.

Things You'll Need

  • Cable splitter
  • Extra cable


Step 1

Locate the main cable line entering your home. This is the line which was installed by your cable service provider. It will usually be black with a silver male connector at the end. It will more than likely already be connected to your television or modem.

Step 2

Measure and buy the extra cable you will need to reach from the end of your main cable to the second device you would like to connect. Also, be sure to buy a second piece of cable to re-connect your original device. The cable splitter and extra cable can be purchased at just about any hardware store.

Step 3

Disconnect the main cable from the television or modem. Now take the end of your main cable and hold the connector between your thumb and forefinger. Locate the female connector on the cable splitter labeled "In" and insert the main cable. Turn the main cable connector clockwise until it has been screwed in tightly.

Step 4

Take one of the cables you purchased and connect either of the male ends into one of the female connectors on the splitter labeled "Out." Screw the other end of this cable back into your original television or modem.

Step 5

Connect one of the male ends of the remaining cable into the other female connector on the splitter also labeled "Out." Take the other male end and plug it into your second device. If connecting or reconnecting a cable modem, it may be necessary to reset it.

Tips & Warnings

  • Make sure to buy a few feet more cable than you think you need. This will ensure you have enough cable should you decide to move your device at a later time.
