2 Analog Television Transmitters
Significant advances continue in TV transmitter technology. New technology and ideas have been introduced to continue to provide high-quality TV signal transmission while improving reliability, reducing maintenance, and lowering overall cost of ownership. These new technologies include solid-state power amplifiers for VHF up to 100 kW and UHF up to 30 kW, plus improvements in UHF high-power tube transmitters. Further, the Federal Communications Commission (FCC) continues its policy of technical deregulation, which allows more flexibility in transmitter design and system operation. This chapter discusses the relevant technology and provides the information needed for selection, installation, operation, and maintenance of TV transmitters in today’s environment.
