AT-1005 Antenna Training System has been 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 standalone mode as well as be interfaced with a computer via RS-232 interface. In this Receiving Antenna can be rotated from 0 to 360 Degrees automatically with the help of Stepper motor controller unit and accordingly Receiving Antennas Signal strength can be monitored. 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, 22 Antennas, RF Transmitter, RF Receiver, Stepper Controller Unit, 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 and estimate VSWR and impedance
  
• 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
  

 
Available Models:

• AT-1003 (Tx Frequency 600-750 MHz + 11 Antennas + Radiation Plot Software)

STC-24 or ST-1102 Satellite Communication Training System is the first of its kind using actual techniques of satellite communication. It can uplink a given signal to a satellite link emulator, which can be stationed up to 100 feet away. The satellite will then re-transmit the same signal at a different frequency to a downlink station, which will receive the signal. Audio signal can be fed through a condenser microphone provided at Transmitter and reproduced on built-in loud-speaker at Receiver. Video signal can be sent from CCD camera and viewed on a video monitor provided with the system. Actual emulation of satellite communication link can be performed with emulation of path loss, propagation delay, noise, fading, etc.

Features:

• Microwave operation
  
• Tele-command and telemetry facility
  
• Manchester encoding & CRC error checking based PC-PC communication
  
• Emulation of signal fading, thermal noise
  
• Variable propagation delay.
  
• Variable path loss at two ends of uplink and downlink channels
  
• High RF output power and low noise
  
• Digital display of PLL synthesized frequency in Transmitter, Receiver and Satellite Emulator
  
• Condenser microphone and speaker provided for audio link
  
• Camera and monitor provided for video link
  
• Satellite emulator has built-in antennas, frequency transponder for communication link
  
• Helix (LHCP & RHCP), Yagi, Dish & Patch antennas provided for linear & circular polarization study
  
• Signal monitoring outputs at uplink & downlink
  

Available Models:

• ST-1101 or STC-10: Basic Satellite Trainer 2.4 GHz
  
• ST-1102 or STC-24: Advanced Satellite Communication Trainer 2.4 GHz
