The digitization of terrestrial television broadcasting around the world has been carried out for 20 years. So far, the digitization of terrestrial television broadcasting around the world has entered another stage, which is the improvement and update of the system. For example, DVBT, which is dominated by the European Union, has evolved to DVBT-3. The ATSC system in the United States was developed early, so some modern digital technologies could not be used, just like heroes with no place to display their prowess. It was not until the recent promotion of NextGen that the difficulties previously faced, such as easily interfered signal and no mobile receiving function was solved, and it also provide the seamless integration of wireless broadcasting and the Internet. But it also came at a price, as NextGen was completely incompatible with the previous version (ATSC1.0.)
Will these evolutions affect DTV antennas? The general answer is no, because the use of antennas is only at the physical layer. Basically, no matter how the baseband changed, even from analog to Digital, it will not have a direct impact on the reception of radio waves. On the contrary, because of the re-planning of the spectrum, it may affect the benefits and efficiency of the antenna receiving band converging range, such as the high-end UHF band of terrestrial TV broadcasting in the past, from 890MHz, down to 860MHz, and then to 700MHz. In the United States, the FCC Repack plans to even reduce it to 608MHz. However, for users, there are generally no obvious problems of general reception in radio signal layer.
However, from the previous CRT TVs, to LCD TVs, to flat large TVs, these evolutions are believed to have also changed the living room and living room furnishings of most households. For this reason, with modern TV sets, every family will also want to upgrade to a DTV antennas with proper and optimal design.
