6 Foot RCA Video Cable to RF Coax TV Adapter Converter for the Atari 7800 System. This setup replaces the switch box that was used in the 80's to connect your Atari 7800 System to your TV or Monitor. Simply connect the RF adapter end in your TV or monitor that has a coax connection. NOTE * please do not expect the highest quality picture. It does not happen with the RF connection option. The RF picture quality can range from good, decent, to poor depending on the condition of your Atari 7800 RF port. If you have very poor quality picture after connecting this setup. Your Atari 7800 has a bad RF port. Video shows the setup working on my Atari 7800. Flip the switch on your game system to channel 3 or 4 also on your TV well to see which channel works best for your setup. I ship worldwide. Shipping rates vary depending on your location.
