ATS-A Antenna Trainer has been designed for teaching and demonstrating the various general purpose antenna configurations. Practical verification of theoretical concepts is easily possible because students can carry out accurate and repeatable measurements of Polar Plots
(involving 360/72 measurements).
ATS-A Antenna Trainer comprises of two towers for mounting the transmitting and receiving Antenna, 50-860MHz PLL Receiver and Signal Generator, 20 Antennas, Antenna Stepper Positioner, Antenna and Polarization kit, Directional Coupler, Current Probe etc.
ATS-A Antenna Trainer works in standalone mode as well as in conjunction with a PC. Suitable offline Windows Software can greatly enhance theunderstanding of various concepts related to antennas.

ANTENNAS - 20 NOSbr>
Dipoles-4, Yagis-4, one each Log-Periodic, Loop, Quad, Vertical, Discone, Endfire, Broadside, Shielded Loop, Telescopic Dipole,Helical, Rect Slot and Cylindrical Slot
CURRENT / SNIFFER PROBE
For study of Current variation across the Antenna Elements
DIRECTIONAL COUPLER
Used for the measurement of Vincident , Vreflected for VSWR computation
ANTENNA KIT
Students can experiment fabricating their own antenna using the Antenna Kit. They can obtain the Polar Plot of their antenna andwithin limits of environmental factors ascertain that they agree with theory.
POLARISATION KIT
Quick connect rotator for Polarisation study of various antennas.
S-54P POSITIONER
Stepper Positioner rotates the Antenna by 1 deg or 5 deg steps. The positioner is controlled via centronics interface by the Receiver
which makes automatic level measurements at end of each step and stores the readings in the selected array.
WINDOWS SOFTWARE - 2 POLAR & 2 CARTESIAN PLOTS
Polar & Cartesian Plots of levels and cursor measurements of Beamwidth, Gain, Side Lobe, Angle, file saving and recall, printouts,
etc, are possible using Antenna Software.
