How do I get an old analog TV to work with a cox digitizer?

[Rick Claude]

I have an old barely used analog TV that worked great and when I hook up the Cox converter box to that TV I can only get 3 workable channels. My digital TV's work fine with the Cox Box. Do I need to buy a separate digital to analog converter that connects in-between the Cox Box that I rent to the analog TV to receive the digital channels clearly? Any advice would gladly be appreciated. Thanks in advance!

What is the connection type between converter box and TV? RF/Coax? Component? S-video? Composite/RCA?
