My understanding is that in the US most digital channels are on UHF, if this is correct, an analog era antenna designed for the VHF channels only will not give you the best signal, but may work (see first paragraph).

That's what a lot of people don't understand.  Just because you punch in "2.1," which is the PSIP (and station ID/marketing channel) doesn't mean that the station is actually transmitting on 54-60 MHz.  It might be on Channel 20 or another UHF channel.  Or it could actually be transmitting on Channel 7 or another VHF-HI channel.  In fact, the VHF-LO channels are rarely used anymore, although that may change after repacking is done.  The TV keeps a lookup table after scanning to match the PSIP to the actual RF channel.

That is correct. For example, channel 2 in Saint Louis is actually broadcast on 584 MHz, not 54 MHz like in the analog days.

Analog  TV  was such  a bandwidth hog, good riddance.

I am one of the cord cutters.  I haven't watch broadcast TV  for at least three year.  I do 80% of my watching using  Netfix, Hulu, Crunchroll (anime), Funamation, Youtube and other streaming services.

 A coat hanger still performs the same as a $35 digital HDTV pancake antenna. I returned it to the store the next day.

Overall, digital TV provided by cable is superior in every way to all forms of OTA.

Yes, I have to pay for cable, but I have access to 311 TV channels and a large number of audio channels that provide local, national and international radio stations.

It has been at least 15 years since I have seen any “snow” or other artifacts. If your experience is worse than mine, the problem is not the technology; it’s the cable service provider.

Not in EVERY way, OTA is free. Wink

How many of those 311 channels you regularly watch? When I had cable, I would regularly watch maybe 10 channels, of those, 6 or 7 are also available OTA.

Four-bay bowtie antennas can be easily built for about $5.  I've built several and they work great in suburban areas, even indoors.  But they're designed for UHF, not VHF/UHF.  They'll work well enough on Channels 7-13 if you're within 15-20 miles of the stations, but that's about it.

I've never had cable, I watch live TV as digital OTA. According to everything I have read, the OTA digital signal often uses less compression than the cable digital. I do know, from experience, that the OTA picture is visually excellent and easily matches or surpasses what I see when visiting the homes of people who have cable. Their picture is very good too, mind you!
