As of June 13, 2009, every full-power TV station in the U.S. stopped sending analogue broadcast signals. These analogue signals were replaced with digital signals or what is often called DTV, or digital television. The new digital signals offer superior audio and video quality, but older TV sets with analogue tuners are unable to display them without a DTV converter box. Connecting this digital-to-analogue converter box only requires one additional coaxial cable.
Unplug the television set. Place the DTV converter box on or near the TV.
Disconnect the coaxial cable connected to the back of the television's "Antenna In" or "RF In" jack. Connect this to the back of the converter box using the "Antenna In" or "RF In" jack.
Connect one end of the coaxial cable to the back of the converter box using the "RF Out" or "Out to TV" jack. Attach the other end of this cable to the back of the TV in the "Antenna In" or "RF In" jack.
Plug the television and converter box into a wall outlet and turn them both on. Turn the TV to channel 3 or 4.
Use your converter box remote and follow the on-screen instructions to complete installation.
