Radio communications are essential to the operations of Federal, State, and local law enforcement and correction agencies. Effective and reliable communications systems not only enable personnel to perform their functions efficiently, but also help ensure their safety. It is, therefore, very important that all components of a radio communications system be selected and integrated to produce an effective design. Understanding the capabilities and limitations of a communications system ensures that it is used most effectively and that performance expectations are realistic. This guide focuses on a key portion (subsystem) of the radio communications system-the antenna system. Although the antenna itself may be the most visible element of radio communications equipment, it is often the least understood. This guide defines and describes the components of the antenna system as well as the fundamentals and characteristics of the antenna itself.
