Take it up with the FCC:

You take it up with them. But you do realize they publish a complete spectrum class allocation for all bands. Undoubtedly, this was created to de-conflict interference in over-the-air usages.
I am not saying that there aren’t digital TV signals; they just aren’t ‘digital’ when transmitted to and received by an antenna over the air - this is what you would call the analog domain. This fallacy helps to propagate disingenuous sales techniques some sellers us to sell antennas to customers under the nomenclature of “digital antennas.” There just ain’t no such animal. They are just regular antennas that have the proper bandwidth and performance to pick up the spectrum-shifted content for HD.
I have a Home Depot “regular TV” antenna that I made sure was operable in the new spectrum shifted HD band and I perfectly receive Atlanta HD signals over 60 miles away.
Don’t get taken in by hype.
