Modern TV transmissions are digital:
https://en.wikipedia.org/wiki/Digital_television
They’re sending 1s and 0s which is why we now get 4 channels in what used to be one channel. Analog is dead, at least in TV land.
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.
