I’ve never seen an antenna that used HDMI, and I’ve only seen USB used for powering an amplifier, so I think your antenna sounds completely normal. (ie: the signal connection is the coax cable/f connector connection.)
I've tried all the above mentioned steps, but I think the problem is my antenna connects to the cable input and the USB, not HDMI. The USB option does not show on the system options. I've added it as "on" vs. "prompt". Only the HDMI inputs show. I'm not getting any local major networks other than the news. How do I get the USB connection to be "read" by the TV to access local channels?
