One cable line is often not enough for households containing multiple media devices. If you would like to connect your television, as well as a DVD player or other equipment, you will need to split your coaxial cable lines. You can use a coaxial cable splitter to split the line originating from your wall, or cable box, to supply a signal to more than one component.
Buy a coaxial splitter with the appropriate amount of output coaxial connectors, based on your needs. For example, if you want to connect a television and DVD player, you will need to buy a coaxial splitter with two outputs. You can buy coaxial splitters at most electronics retail stores and at many popular big-box retailers.
Measure the amount of coaxial cable you will need. Measure first from the wall to the location you want to mount the splitter. Then, measure from the coaxial splitter to each electronic device you want to connect it. Buy the appropriate amount of coaxial cable needed, based on your measurements. You can buy coaxial splitters at most electronics retail stores and at many popular big-box retailers.
Connect a coaxial cable from the wall coaxial jack, to the input connector on the coaxial splitter.
Connect a coaxial cable from the output of the coaxial splitter, to one of your electronic devices. Repeat this step until each component is connected to the splitter.
If you own a satellite or cable box, the wall coaxial connection must first be connected to the input of the box. The splitter must be installed from the output of the box.
