This video shows you how to connect an old games console to a new TV via RF and still keep your digital TV channels. In the video I used a Sega Mega Drive (Genesis) and Samsung 4k television. By manually tuning in the analogue channel you will not lose your digital channels unlike when you use the auto tune on the TV. If you have the option to use AV which you will do on most consoles apart from the very early ones (like Atari 2600) then it will produce a better picture than RF.
