After World War 2, the advent of television broadcasting motivated extensive adaptation of the Yagi–Uda design for rooftop television reception in the VHF band (and later for UHF television) and also as an FM radio antenna in fringe areas. A major drawback was the Yagi's inherently narrow bandwidth, eventually solved by the adoption of the very wideband log-periodic dipole array (LPDA). Yet the Yagi's higher gain compared to the LPDA makes it still required for the best fringe reception, and very complicated Yagi designs and combination with other antenna technologies have been developed to permit its operation over the broad television bands.
