Antenna trainer 0.005-2 GHz

  Product Brief :

Antenna Training Lab ATS20

Antenna Trainer Lab has been designed

to provide useful tools for hands on experimentation and

teaching of various commonly used antennas in VHFUHF-

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.

The system consists of a set of two tripods one for

mounting the transmitting antenna and another stepper

motor controlled antenna positioning tripod for mounting

the receiving antenna, 30 different types of antennas,

PLL synthesized Digital RF Transmitter, PLL

synthesized Digital RF Receiver & Stepper Controller

and all the necessary cables and accessories.


* 30 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 variety of


* 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 &

VSWR plots, Multiple pattern overlay, Double

cursor measurement, Zoom, Colour editing,

1000 location editor, Absolute/Relative

measurement , 3dB/10dB beamwidth
