Antenna Training Setup

Antenna Training Setup/Antenna Learning Training Setup/Antenna Trainer:

The Antenna Trainer System is ideal for introducing the principles of Antenna operations and design. This training system includes a set of modular mechanical elements forming various antennas, a transmitter unit and a detector unit. The Antenna Training System comes with a motorised antenna unit that allows for the automated recording of radiation patterns of the antennas. This operation is normally performed by rotating the transmitting antenna at different angles by hand and measuring the radiated intensity.

The motorised antenna unit consists of a microcontroller based system for capturing, displaying and printing of the antenna radiation patterns. The system captures a signal at an interval of ten rotations driven by a stepper motor and the radiation pattern is then displayed on the PC.
