VHF and UHF Antennas
The WTC2000V Antenna is designed for receiving and transmitting high frequency signals with vertical polarization in the frequency range from 118 MHz to 137 MHz.
The antenna suppresses surface currents and provides high protection against lightning strikes by short circuits of the radiating surfaces on the direct current. The short circuit is provided by a connecting tube placed inside the vibrator. The construction of the antenna allows it to resist high wind forces and mechanical loads and provides a low wind profile. The low weight and small dimensions are additional benefits of the antenna.

WTC2700 Multiliterate and ADS-B System
WTC2700 is the state-of-the-art scalable, modular solution for providing aeronautical surveillance using multiliterate (MLAT) and automatic dependent surveillance – broadcast (ADS-B) technologies.

WTC-6754S S-band primary surveillance radar with monopulse mode S secondary surveillance radar
Purpose
The new generation airfield radar has advanced capabilities of detection of aircraft position in terminal areas and provides conditions for transition to reduced separation rules in terminal areas with the aim of capacity improvement of the aerodromes.
Key Features
Hardware
- Use of up-to-date electronic components and engineering solutions allows to place all the hardware of primary and secondary channels in one standard cabinet;
- Minimization of the dimensions of the hardware allows, in turn, to increase the reliability of the radar and to place all the hardware in one shelter, and to install the shelter itself directly on the mast.
Antenna of the primary channel
- emitter-polarizer is placed outside the beam, which allows to increase the gain and reduce the side-lobe level;
- integrated dipole of the test generator that allows to test the whole processing path, including the antenna.
Drive string
- in the drive string, control signals to an antenna and status signals from the antenna are transmitted in a noncontact manner, that is why there are no slip rings in the string, the sliding contacts of which often lead to failures of radars;
- position sensors of the antenna are directly connected to the antenna; such transmission does not have backlash and kinematic errors, which allows high-accuracy measurement of rotation angle of the antenna.
Ground receiving stations:
- High reliability (MTBF, MTTR);
- Receiver with three independent receiving channels and sector (120⁰) antennas provide high spatial selectivity of signals and the ability to detect spoofing;
