Thank you for posting your question to our support forum. Here is the solution for you. You can crimp both ends of your RG6 cable with a BNC connector. This one on our website is for RG59 but we also carry BNC crimp on connectors for RG6.
Here is the one for RG59.
Then on the TV end you can use a BNC to RCA converter which will allow you to connect your TV's RCA video input.
If you call us tomorrow after 9:00 AM EST we can place the order for you over the phone being that the RG6 BNC connector is not on our website.
Please let us know if we can help further.
