    Digital converter boxes output their signal over cable (coax or HDMI, etc) NOT air. - some old (small) tv devices were antenna only.

    I mean, the old devices could be modified, but you don’t always wanna do that.

      That coax output you mention contains the OTA signal, but yes, you’d likely need to amplify it within the limits of your local laws to broadcast it any usable distance.
