Reliable communications are needed to provide vital links between distant countries. Today's worldwide communications depend on complex networks of microwave systems. Voice, data, video, long distance, and local transmissions all use microwave technology. The importance of global communications has increased the need for qualified microwave technicians. To do so we offer the Nida series 130 Microwave Training System prepares technicians for microwave system maintenance. The program presents microwave theory with  applications in microwave hardware, circuitry, and systems.
