Actually...AND I correct myself.

In response to 141538: a bridge too far, posted by Rich E2 on Tuesday, 19 December 2017, at 6:29 a.m.

The HDTV signal does just fine with 20th Century antennas. Also, I'll correct an earlier statement I made that claimed only the UHF part is involved - I was incorrect. Both VHF and UHF reception is required. Digital simply uses far less bandwidth than analog broadcast & so the FCC was able to sell those new, clean frequencies between the channels at auction. As far as reception of HDTV, either:

1. you have enough signal to render the HDTV stream;
2. you have a weak signal that works sometimes but drops out other times - but HD when it's there; or
3. too little signal to lock onto in the first place.

The industry made a big deal of having "special" antennas for receiving digital broadcasts. Good marketing - not great science.
