From Wikipedia search for Television Antenna:
"Starting in 2006 many countries in the world switched from broadcasting using an older analog television standard to newer digital television (DTV). However generally the same broadcast frequencies are used, so the same antennas used for the older analog television will also receive the new DTV broadcasts. Sellers often claim to supply a special "digital" or "high-definition television" (HDTV) antenna advised as a replacement for an existing analog television antenna; at best this is misinformation to generate sales of unneeded equipment, at worst it may leave the viewer with a UHF-only antenna in a local market (particularly in North America) where some digital stations remain on their original high VHF frequencies."https://en.wikipedia.org/wiki/Television_antenna
