Hooking up your TV or cable box to a cable jack is one of the first and easiest things you need to do to set up your TV. Sometimes, however, the cable jack in the room where you want your TV isn't close to where you want your TV set up. This doesn't mean that you have to change the layout of your room and put the TV right by the jack. By getting an extra piece of coaxial cable and a RG6 coupler, you can connect your existing coaxial cable and make one long cable that will reach the desired location of your TV.
Screw one end of the first piece of coaxial cable into the cable jack on your wall.
Screw the other end of the first piece of coaxial cable into either end of the RG6 F coupler.
Screw one end of the second piece of the coaxial cable into the other end of the RG6 F coupler.
Screw the other end of the second piece of the coaxial cable into the back of your TV, cable box or other video component.
You can avoid the need for a RG6 F coupler by using a longer piece of coaxial cable.
If you experience connection issues with your cable after you've set it up, make sure all of the connections--wall to coupler, coupler to TV or cable--are secure. If they're not secure, you could experience a low-quality picture or no picture at all on your TV.
