are only broadcasting on cable.
All the majors are still broadcasting over the air as they have been doing since they came into being.
The only difference is that when the FCC mandated that all TV Broadcasts would be Digital, the broadcasters had to shift their transmitter frequencies from the VHF band up to the UHF band. (this usually meant changing out the transmitter, but that's another story)
Some affiliates, notably FOX, were already using the UHF band prior to this mandate, but not digitally. You don't remember the fuss about Monday Night Football?
Anyway, UHF antenna's are available just about anywhere TV's are sold. Some are referred to as HD antenna's, some are not, but there is no difference between a regular UHF antenna and a so-called HD antenna.
UHF is far more directional than VHF so the antenna should be pointing at the transmitter tower.
FWIW, all the majors transmit HD at 1080 over the air. This results in a much better HD picture than those transmitted by Cable or Satellite and certainly much better than any webcast.
Just saying
P
Is there any way to access the 3 major networks anymore, without cable??? Or perhaps a way to catch the NBC broadcast of the parade somehow and stream it from a computer or phone to the big screen tv? What about through Amazon Prime, or XBox Live? It seems like there must be some way to get a regular network tv broadcast without cable. There must be oodles of Americans living overseas, or living in the US without cable, who would love to see the parade. WHY doesn't NBC do a webcast? (Sorry, that's a lot of questions in one).
