The Digital TV Antenna
When it comes to watching TV, a digital TV antenna is a television antenna that allows you to receive digital signals over the air. It is similar to an analog antenna because it interprets signals it receives in order to provide you with television entertainment and media. However, digital signals generally provide a clearer picture, and television is no longer sent over analog signals.
A traditional analog antenna, or “rabbit ears” as they were sometimes called, used to pick up analog RF signals in the air. The antenna could receive the information and display television programming. Digital antennas serve essentially the same function, but the information they are receiving is transmitted digitally, and not with analog RF signals. While most digital signals are broadcast in high definition, having a digital TV antenna alone is not sufficient to ensure having access to high definition TV. The TV must also be able to display in high definition and to decode the high definition digital signals in order for a digital TV antenna to provide you with high definition TV.
