The antenna characteristics that determine the suitability and effectiveness of antennas for law enforcement use are also presented. Only the following four frequency bands are considered: 25-50 MHz, 150-174 MHz, 400-512 MHz, and 806-866 MHz. This standard supercedes NILECJ-STD-0205.00, Mobile Antennas dated May 1974. This revision has been written to include mobile antennas operating in the 806-866 MHz frequency band, and it also provides a substantially improved standard radiation test site that uses an elevated metal ground plane. In addition, the relative antenna gain requirement and test method have been replaced by a gain-transfer requirement and test method. 4 references.
