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
