over-the-air (ota) digital television (dtv) requires a stronger signal than an*log tv. additionally, most dtv broadcast are in the uhf frequency band instead of the vhf band. uhf signals are higher in frequency and do not pas* through or around objects as well as vhf signals. also, over-the-air transmission and cable losses are greater at uhf frequencies. antennas that picked up an*log tv signals will also pick up digital tv signals, if the signal is strong enough. a digital television's picture quality is either 100%, or nothing. there is not a gradual degradation of picture for weaker signals, it's a steep cutoff. in contrast an*log pictures degrade gradually, weaker signals have more noise or snow in the picture. an*log tv broadcast in the united states ended june 12th (friday), 2009. since the introduction of digital tv, the number of over-the-air (e.g. 6.3 or 6-3). the number of sub-channels varies from 1 to 7 or more. a stations's tv channel could be the same as it's rf channel, but in most cases they are different. in 2009 most an*log stations changed their rf channel (and most vhf stations moved to uhf) for the dtv transition, but were allowed to stations changing their rf broadcast channel, but not their virtual tv channel. or surround sound. most sub channels have program guides, closed caption, language, and other options. cable and satellite operators often compress local channels before re-broadcasting. the compression reduces picture quality compared to over-the-air broadcast. compressing signals opens up more bandwidth and allows providers to squeeze in more channels nobody watches. there is no difference between a digital antenna and an an*log antenna, except the name. digital and an*log tv signals both use the same carrier frequencies (vhf or uhf band), carrier modulation (digital or an*log video) does not effect antenna reception. avoid pointing through metal backed insulation, duct work, etc. some station's changing rf channels between 2017-2020+ some dtv stations will be changing rf channels over a 3+ year period,
