ABSTRACT
The use of electromagnetic energy for communications has increased dramatically since the last edition of the NAB Engineering Handbook was published. This chapter updates previous versions, including new and revised standards in force, emphasizing the requirements on broadcasters, and describing methods for measuring radio frequency (RF) energy. Three issues important to broadcasters are still in development:
• The International Committee on Electromagnetic Safety (ICES) has revised IEEE Standard C95.1, further harmonizing it with the standard published by the International Commission on Non-Ionizing Radiation Protection (ICNIRP). IEEE Standard C95.7, specifying recommended practices for RF safety programs, was also recently published. Although these standards are now “in force,” regulatory agencies have not yet taken any position on their adoption or use.
