An antenna useful for seeing analog TV across atmosphere can also be used for digital television, including HDTV. Viewers in a few areas, however, will find that a better antenna—a rooftop one, perhaps—is needed to ensure dependable digital television reception.
First, a term on how digital television reception differs from analog: Essentially, either you get an ideal digital signal for a certain channel, or very little. it is what’s known as a “cliff result.” You will definitely either get at the really peak of reception capacity or—less happily—in the deepest ditch.
Digital reception is unlike the familiar world of analog, for which a limited sign above a particular limit could be viewable (or eventually hearable), albeit with static or any other defects. In case your electronic reception is erratic, it's going to be hard to tolerate, because at varying intervals the picture and sound will recede totally. You may not wish watch Dateline if Stone Phillips gets replaced every few seconds by a blank, blue screen (though I actually favor it in that way). If you reside in an area where reception is limited, a bargain-priced interior antenna may well not cut it any longer. Even visitors just who inhabit towns close to broadcast transmitters may encounter interference caused by neighboring structures, hills, woods or other obstructions.
To view all television programs locally, you will need an antenna for both VHF (stations 2 through 13) and UHF (stations 14 and up) rings. Utilizing the change to digital during 2009, numerous channels will relocate to brand new networks and, in some cases, switch rings.
Your antenna should point toward it station’s broadcast tower. In the event that you encounter reception issues because local stations’ transmitters are found in numerous guidelines, consider setting up a rotor (often called a rotator) that may reorient the outdoor antenna relating to which channel you are seeing.
