A Digital tv antenna is a device designed to receive over-the-air (OTA) digital television broadcast signals transmitted by local TV stations. Unlike analog Antennas of the past, modern digital TV Antennas are optimized for the ATSC (Advanced Television Systems Committee) digital broadcast standard used in North America — including the next-generation ATSC 3.0 (also known as NextGen TV) — as well as DVB-T/T2 (Europe, Australia) and ISDB-T (Japan, Brazil).
Digital TV Antennas receive free, uncompressed HD broadcasts from local networks such as ABC, CBS, NBC, FOX, PBS, and many sub-channels — without requiring a cable or satellite subscription. The signal is digital, which means picture quality is either perfect (crystal-clear 1080p, 4K where available) or absent — there is no "snowy" picture as with analog signals.
