I believe that you can use the digital/analog converter boxes that started to pop up when UHF signals were phased out. Those have Coax in and both coax and composite (and it some cases S-Video) out.



They run about $30-$40 or less. Can anybody confirm that those work as a pass-through for analog signal from an RF system like a 2600? I would imagine that they do.
Even though this won't help the OP, I'm curious about the answer as well. I wasn't aware that newer TVs weren't coming with coax inputs, and I might want to grab one of these converters from Dad while he still has them.
