Radio History: NES on VHF
Did you know the NES and other devices had an RF output to connect to the tv?
The RF (Radio Frequency) output on the NES sent both video and audio signals combined over a single channel in VHF, allowing the console to connect to older TVs through the antenna input. Instead of separate cables for sound and picture, the RF output used the TV's tuner to display the game, much like how broadcast TV signals worked at the time. While not as sharp as later video outputs, it made the NES compatible with a wide range of TVs from the era.
