Since we (U.S.) have gone digital, OTA, unless you are real close to the transmitting antenna, just about requires your antenna be connected to an amplifier. They don't broadcast OTA with as strong a signal as they used to. I use a little antenna I bought from Radio Shack that has an 10db amp and get great reception from Charlotte locals and i'm in Troutman NC. I'm lucky, my U-verse has only been out once in 2.5 years and that was just the other day. Too bad I'm leaving over another issue that I have no option to "Rethink Possibilities" with and have a future with U-Verse/AT&T.
Actually, the transmit power level is the same as it was when the station was broadcasting NTSC analog.
But ... (isn't there always a "but"? )
The ATSC digital OTA signal is much more prone to problems with multipath distortion, impulse noise (especially for VHF low frequencies e.g. channels 2-6), and doppler shift. This makes it such that the ATSC signal does not cover nearly as large of a geographical area as the NTSC signal did at the same transmit power.
In fringe areas, the NTSC signal was receiveable but just had a bit of snow in it (which was noise caused by amplifying the very weak signal). In those areas now, the ATSC signal will have the same amount of noise when amplified, but then the signal becomes non-decodable, thus no reception.
