Basic principles of radio communications, including ground wave and sky wave propagation, spectrum principles, intuitive use of decibels and test equipment, link fade margin calculations and coverage predictions, longitudinal multipath and vertical antenna patterns, use of directional antennas. Covers in detail siting principles, site design considerations, feedline protection devices (cavities, circulators/isolators, crystal filters, duplexers), microwave path haracteristics. Receiver, transmitter, and phase locked loop design concepts are also covered. Recommended for engineers, technical support personnel, and (very) enthusiastic maintenance technicians.
