An RF modulator is a device for converting a coaxial cable jack on older televisions into a set of RCA-type composite audio/video jacks for connecting newer types of equipment, such as DVD players. Decades ago, when television sets typically connected with a coaxial cable for satellite or TV service, and possibly a VCR as well, a simple coaxial jack was the only necessary connection point. With an RF modulator, older TV sets can still be used with modern AV components.
