6 Foot RCA Video Cable to RF Coax Adapter Converter for the Colecovision & Intellivision I & II System. This setup replaces the switch box that was used in the 80’s to connect your Colecovision or Intellivision 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 Colecovision or Intellivision RF port. If you have very poor quality picture after connecting this setup. Your Colecovision or Intellivision has a bad RF port. Actual screenshots using this setup on my Intellivision II. 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.
