Since 1997 the US has had "new" broadcast TVs that can pick up the new HD broadcast standard: ATSC. It ran side-by-side with good old NTSC until 2009, and since then, it is the only TV standard broadcast over US airwaves.
It still uses the same VHF and UHF antennas as the old days, however reception range is lessened compared to analog.
Since I dumped cable TV (even for just locals), ATSC is what I use: I have rabbit ears feeding my 46" HDTV. I get everything but NBC… surprise surprise, guess what company is owned by Comcast, and thus doesn't care to do over-the-air broadcasting well?
TV set makers want to transition us to a non-backwards compatible ATSC 3.0 system starting a few years from now, but they'll get tremendous blowback. Most Americans only transitioned to HDTVs in 2008 or 2009.
You pretty much lost me with the new technology. I do not know how that works in rural areas.
My business was radio electronics, but as a side line I sold the old 12 foot dishes that picked up C band sat transmissions. OK, that was 30+ years ago. I am now happy with my G-sat Ku band system.
