The DAB (Digital Audio Broadcasting) frequency range is the band in which the car antenna receives digital radio signals. DAB offers higher sound quality and a wider choice of stations than traditional FM and AM broadcasting. DAB frequencies vary by region, but typically range between 174 and 240 MHz (VHF Band III) or 1452 to 1492 MHz (L-Band). Autoantennas with DAB frequency ranges are ideal for users who want to enjoy the benefits of digital radio, such as clearer sound and more available stations.
