From within Settings/TV Inputs, look for an input named "Live TV". (This is the default name of the OTA/Antenna and may be located under "Inputs not Used".
After selecting "Live TV" Input, go to "Rename" on the right hand side. (Settings/TV Inputs/Rename). Then rename the Live TV to "Antenna TV" or select the option "Set Name and Icon" and change it to whatever you wish.
