They all use the same coaxial input ( the one the cable is usually screwed into ), and it is far more obnoxious to unscrew the cable, screw in the console, then re-screw the cable after than it is to replace the composite cables for my newer systems.

:To answer your question, the ATSC converter boxes are really separate tuners : antenna plugs in to the box, box outputs audio and video via coax or composite cables to TV, TV remains on channel 3 or video input, and you use the ATSC tuner's remote to change channels.
