Antenna Trainer Lab

  Product Brief :

Amitec Antenna Trainer Lab ATS20

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 Rs232 port.

The system consists of a set of two mounts – one for

mounting the transmitting antenna and another stepper

motor controlled antenna positioning mount for

mounting the receiving antenna, 35 different types of

antennas, PLL synthesized Digital RF Transmitter, PLL

synthesized Digital RF Receiver & Stepper Controller

and all the necessary cables and accessories.

* Different types of adjustable Antennas like

Log Spiral, Batwing, Stacked Yagi, Helix, Quad,

Slot, Log periodic, Discone, Biconical, GPS

Patch, Parabolic dish etc. are offered

* User selected variable transmitter & receiver

frequencies and adjustable antenna lengths to

cover wide frequency range for experiments.

* PLL stabilized antenna transmitter and receiver

operating in the frequency range of 5-2000

MHz with 50 KHz step size for full Range

testing and modeling of antennas.

* RS232 interface with polar plotting software

with log, linear cartesian and polar plots, Vi, Vr &

Return Loss plots, Multiple pattern overlay,

Double cursor measurement, Zoom, Colour

editing, 1000 location editor, Absolute/Relative

3dB/10dB beamwidth measurement
