This document establishes minimum performance requirements and test methods for mobile antennas mounted on vehicles used by law enforcement agencies.
Abstract
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 In addition, the relative antenna gain requirement and test method have been replaced by a gain-transfer requirement and test method. 4 references.
