Tv Rf Modulator Schematic. A uhf modulator, also called rf modulator, is an electronic circuit, which modulates audio and video signals into an rf signal compatible for input through a television aerial socket.earlier televisions did not have any means to feed audio or video signals other than through an aerial socket, therefore, modulators were widely used. According to its designer, it could produce 500 mw output.
