Technical Specification:

mODEL: aNT-3002

ANTENNA TRAINING SYSTEM (MOTORIZED) 

Features:

The ANT-3002 Motorized Antenna Trainer has been designed toprovide useful tools for hands on experimentation and teaching of various commonly used antennas in VHF-UHF-Microwave band in thelaboratory for students of all levels. It can be used in standalone modeas well as be interfaced with a computer via RS-232 interface. In thisReceiving Antenna can be rotated from 0 to 360 Degrees automaticallwith the help of Stepper motor controller unit and accordingly Receivin

 Antennas Signal strength can be monitored.

The system consists of a set of two tripods one for mounting thetransmitting antenna and another stepper motor controlled antennapositioning tripod for mounting the receiving antenna, 22 Antennas, RFTransmitter, RF Receiver, Stepper Controller Unit, Antenna PlottingSoftware and relevant accessories/ cables.
