You can use the Direct Connect T.V. RF Adapter, You can ourchase either on line or you can visit with one of electronic retail stores. it looks like a small bullet, one end which is the female end screws onto your antenna port of your T.V. and the other end should be a smooth end that will fit your coaxial cable from your atari. I find it cheaper the buying another specially designed Universal adapter. you may have to purchase that if your video is not clear with just a Direct Connect TV RF Adapter. Happy Gaming.
