GOLD RCA to RF Adapter for TVs and Monitors with a coax connection for use with the Mattel Intellivision & the Sears Tele-Games Super Video Arcade. This adapter replaces the switch box that originally came with the Intellivision 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.
