27、4-C xi INTRODUCTION This standard is intended to provide a standard format for manufacturers of antennas for the Terrestrial Land Mobile Radio industry to adhere to. It was motivated by the observation by propagation software providers (i.e. users of such patterns) that many manufacturers have propr
28、ietary formats and that a single standardized format would make software development simpler, assure consistent usage of antenna pattern data, and facilitate data accuracy through a robust, common data format. .
