Splitting the feed from your outdoor television antenna is an efficient way to distribute TV signals around your home or office. The easiest way to pipe your antenna signal to more than one television set is to install a coaxial cable "splitter" device. A range of devices is available, from two-way to eight-way splitters, allowing one antenna to serve multiple television sets. Signal strength will drop each time you divide the antenna feed, so you may need a preamplified antenna to boost the signal before it reaches the splitter.

Things you need
- Digital-television grade coaxial cable
- Cable connectors
- Cable clamps or ties
- Power drill
Survey the installation site and calculate how much coaxial cable you will need to run additional lines from the splitter to each television set.
Disconnect the original coaxial cable from the input jack on your main television set or digital-television converter.
Fix your coaxial cable splitter to the wall, or a baseboard, using the supplied screws. Mount the splitter near the original coaxial cable.
Attach the original cable (from the antenna) to the "Input" socket on the splitter. This will screw in or plug into the socket.
Install the additional lines of coaxial cable from the splitter site to the locations of the additional TV sets. You will need a power drill to create passage holes for running the cable through walls or ceilings. Secure cables with cable ties or cable clamps every two to three feet.
Attach F-type connectors to each end of the new cables. (You can buy coaxial cable with these pre-installed).
Connect the splitter end of each new cable to a free "Output" jack on the splitter device.
Attach the other end of each new cable to the input jack on your television set or digital-television converter. (Remember to connect your original TV set to the splitter with a short run of coaxial cable.)
Tips and warnings
- Invest in a high-quality splitter device that balances the divided signals equally between outputs.
- For preamplified television antenna systems, never split the signal from the antenna before it reaches the amplifier's power unit. This may lead to complete signal loss.
