PC Based Motorized Antenna Trainer

PC based Motorized Antenna Trainer has been designed to provide useful tools for hands on experimentation and teaching of various commonly used antennas in VHF-UHF-Microwave band in the laboratory for students of all levels. It can be used in stand-alone mode as well as be interfaced with a computer via USB interface. In this Receiving Antenna can be rotated from 0 to 360 Degrees automatically with the help of Stepper motor controller unit and accordingly Receiving Antennas Signal strength can be monitored. The system consists of a set of tripod for mounting the transmitting antenna and another stepper motor controlled antenna positioning pod for mounting the receiving antenna, 22Antennas, RF Transmitter, RF Receiver, Stepper Controller Unit, Antenna Plotting Software and relevant accessories/ cables.
