RCA to RF Adapter for TVs and Monitors with a coax connection for use with the Atari 2600 Heavy Sixer Junior Jr. Atari 7800. This adapter replaces the switch box that originally came with the Atari game system. This adapter is a much better option that gives you a much clearer and consistent picture. Simply connect your existing rca video cable to adapter and plug in your TV or monitor that has a coax connection. You will receive 1 adapter per purchase. I ship worldwide. Shipping rates vary depending on your location. Combined shipping is available when purchasing multiple items. I ship twice a week, usually every Tuesday and Friday.
