Alan Dick Broadcast Develops DAB Systems to Satisfy Requirements of Hi-Profile Broadcasters
August 26, 2014 --
"Environmental considerations coupled with zoning and planning restrictions forced the BBC to seek an antenna that could be fitted into the space occupied by existing FM units," says Alex Perchevitch, President of ADBL. "Nothing suitable existed, so ADBL embarked on a development project to provide a solution that didn't impact negatively on the FM antenna and met the specification for DAB. Two types of antennas were produced; the Shared Aperture FM Crossbow, and the FM Spearhead."
The FM Crossbow antenna was designed for square structures and provides an excellent omni directional horizontal radiation pattern from an array of 4 panels mounted around a square structure. The FM Spearhead is suited for triangular structures and provides an excellent omni directional radiation pattern from an array of 3 panels mounted around a triangular structure. The DAB antenna elements were designed to be fitted onto the existing FM antennas without disturbing its installation or performance. The systems were range tested to optimize the RF performance of the combined DAB/FM antennas.
