From the late 1970s to the late 1980s, before the advent of MTS Stereo television broadcasts, an additional cable decoder was offered to cable TV subscribers, which was connected to the FM antenna terminal of a radio receiver and broadcast audio simulcasts of television broadcasts on certain frequencies, but separately transmitted in FM stereo, along with traditional local radio stations at their specific frequencies, utilizing the cable system's own taller receiving antenna for maximum audio clarity. For instance, MTV's audio would be offered on a cable radio frequency, thus the video being played in monaural sound on cable would have its television audio muted, and the stereo audio instead heard through the radio receiver.
