Alan Dick Broadcast is taking its DAB antenna offerings to the next level with the Crossbow and Spear.
The company says the FM Crossbow, to be shown at IBC2014, “was designed for square structures and provides an excellent omnidirectional horizontal radiation pattern from an array of four panels mounted around a square structure.”
The company says the FM Spearhead is “suited for triangular structures and provides an excellent omnidirectional radiation pattern from an array of three panels mounted around a triangular structure.”
The two antennas were the result of real-world situations. ADBL President Alex Perchevitch explained: “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 … 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.”
