Antenna Trainer AT-5000 is a low cost high performance antenna training system. It is designed to be used in two distinct ways; for teaching and demonstrating common antenna configurations at all levels of study, and as a design tool by those engaged in research and development of projects in communication.

Antenna Trainer AT-5000 has been designed to act as basic tool for carrying out experiment in the field of antenna for Technical Colleges and Engineering Universities undergraduate and graduate courses. AT5000 comprises of C-Band microwave transmitter, microwave receiver with Digital Voltmeter Display, turn table and set of eight different type of antennas. The transmitter and receiver units have been built in power supplies and hence each is powered from 220 VAC 50Hz supply. Various antennas are mounted directly on the receiver for pattern measurement.

AT-5000 is stand alone, versatile table top system that provides hands on experimentation, understanding, working of Antennas, and plot their polar plots without any high frequency equipment.

Training system includes modular mechanical units construction forming various antennas, transmitting unit and detector unit. Emphasis is placed on the basic design of microwave antennas, pattern in principal planes, polarization and beam width calculation.
