ABSTRACT
This chapter discusses the considerations for planning a new frequency modulation (FM) transmitter facility. When planning a new FM transmitter facility, thought should be given to the location first. While the high-power transmitter may be impractical to power from an uninterruptable power supply (UPS), all the other equipment including studio to transmitter link exciters, remote controls, and audio processors should all be supplied with clean UPS power. An elegant solution to the problems is to employ a master antenna system that is normally a shared resource, and that can handle many FM radio stations at once. Some newer FM transmitters employ liquid cooling. Transmitters and associated equipment are all based on computers, and these types of circuits need to be kept clean and cool to provide reliable operation. The chapter deals with planning amplitude modulated (AM) transmitter sites. The base of the AM tower is hot with radio frequency and insulated from ground.
