How would I connect digital technology to this old Zenith TV?

Thanks.

For the AV to RF convertor, does the RF output plug anywhere into the TV? I understand now that HDMI -> AV -> RF, and I would probably choose the second option to buy an HDMI to AV and an AV to RF. I'm just a bit confused as to whether or not the RF output will require any antenna or plugging into the TV.
