That’s the problem with Wikipedia. Not everything it says is true. Categorically, RF waves (coming from and to an antenna) are not digital. Even the transport mechanism to your home “digital” box on cable or fiber is spectral.
The format may be called “digital” but the method of transmission is most always spectral if no wires are involved. Unless you have a completely transmission means like wired parallel signal cable or the like, you have an antenna.
Take it up with the FCC:
