Basic Antenna Trainer Manufacturers

Kotech Export offers a wide range of Antenna Trainers including low cost superior quality basic antenna trainer which is a PC Based Manual Antenna Trainer has been designed to provide useful tools for hands on experimentation and teaching of various commonly used antennas in UHF-Microwave band in the laboratory for students of all levels. It can be used in stand-alone mode. In this system, receiving antenna is rotated manually from 0 to 360 degrees and accordingly the signal strength can be monitored on the Receiver. It comes with a Polar plotting software for storing readings manually.

The system consists of a set of two tripods one for mounting the transmitting antenna and another for mounting the receiving antenna, 11 Antennas, RF Transmitter / Receiver, Antenna Plotting Software and relevant accessories/ cables.

Experiments:

~ Variation of field strength with distance.
~ Plot radiation pattern of omni directional antenna.
~ Plot radiation pattern of directional antenna.
~ Polarization of vertical and horizontal antenna.
~ Study resonant and non resonant antenna.
~ Demonstrate reciprocity theorem of antennas.
~ Study current distribution along the element of antenna.
~ Study different antennas polar plots, radiation patterns, gain, beam width, front back ratio.
~ Comparison of different antennas.
