Are we all getting this right, or is there a difference in getting a signal, as opposed to receiving viewable content? I am not electrically that swift.
It is said there is NO such thing as a DIGITAL ANTENNA, only antennas that can receive VeryHF and UltraHF signals. So the old analog stuff - whether VHF or UHF signal channels - might be received at 70 mi, but be so snowy as to have no content.
And for the new digital signals (also either VHF or UHF), they too might be received at 70 mi, but the content is too dim to have integrity with resulting digital emptyness that is similar, in effect, to the analog snow.
Need the gurus on this.
Just one clarification: All new digital signals are UHF, no matter what the channel number is. The FCC, in the switch to digital, moved the old VHF channels (2-13) to UHF. This was to address frequency clutter and interference in the VHF range. TV's with digital tuners "know" to look for channels 2-13 in the UHF frequencies assigned to them. Since all channels are now UHF (except a few special situations still using VHF), an antenna optimized for UHF will provide the best results. Hence Winegard added the Wingman option to their antenna line.
As mentioned, this clarification is not correct. Here in Phoenix, channels 8, 10 and 12 are still in use. Channels 2-6 are nearly (but not completely) gone and the remaining TV programming is being broadcast one VHF-Hi (7-13) and UHF (14-52). Even the upper UHF channels are scheduled to be reduced down to somewhere around channel 36 IIRC but there will be multiple SD sub-channels (3.2, 3.3) to fill the gap.
The channel number of the screen is "generally" not the broadcast channel. As an additional example channel 5.1 in Phoenix is broadcast on UHF 17. That makes the majority of channels being broadcast on UHF but not UHF only.
