An RF modulator is a device used to convert signals from an RCA device into a television with only antenna/cable input. It usually uses channel 2 or 3. Radio shack will likely have one, but they should also be available at large stores such as wal mart and best buy. They cost about $30.

If you have an old television that has an antenna connection, you will need an RF Modulator in order to connect a DVD player to your television. The function of an RF modulator is simple; the RF modulator converts the video and audio output of a DVD player into a channel that is compatible with a TVs antenna input.
