Those must be quite rare (tvs that old with coax input) There used to be a wide variety of antenna inputs on tvs without any real apparent rhyme or reason. At first there were just screw terminals, then you had sets with screw terminals and a coax. Sometimes the VHF signal was a coax input and the UHf was a 300 Ohm twin lead. Some sets have 4 screw terminals and a jumper that went into the 75 ohm input all of this with no apparent rhyme or reason. I grew up in the 90s and 00s, so by then, the singular 75 ohm coax was standard.
