I don't understand "Internet is currently a no-go as a complete substitute for OTA live content unfortunately", but no biggie. I simply wanted to know what the cord was, I got the answer so thank you to one & all.You can use an outdoor/rooftop mounted antenna for best OTA (over the air) reception. Internet is currently a no-go as a complete substitute for OTA live content unfortunately. Only select streams/live broadcast are available currently in the US, with the exception of NYC anyway (Aereo service).
