Scalable Multi-Band Capability
The system allows for the integration of up to 21 independent modules, creating a dense protective barrier across a wide spectrum of frequencies. This ensures reliable shielding of control and telemetry channels, completely blocking the operation of any unauthorized devices within the coverage area.
Low-Frequency Coverage
in 100–300 MHz
Operation in the 100–300 MHz spectrum effectively shields non-standard control and telemetry channels, preventing any unauthorized UAVs from approaching the protected perimeter. Special layout technology allows the system to be integrated into a compact housing, ready for installation on any transport platform.
Proprietary "Clover" Type Antennas
The "clover" type antenna provides an omnidirectional radiation pattern and guarantees stable density of the protective field regardless of the antenna's position on the platform. This property is critically important for effective shielding of the frequency spectrum when implementing multi-band systems in a compact housing.
Camouflage and Protection
The car-roof-box-shaped housing provides mechanical protection and camouflage for the antenna system, minimizing the impact of external interference (branches, stones, impacts) during the movement of the transport platform.
In-Cabin Control
A separate control unit in the car cabin, all controls in one place — maximum convenience and instant readiness for action.
Custom Frequencies. Tailored to Your Needs
We understand that every project is unique. That's why we offer full customization: individual frequencies, configured specifically for your task.
Automotive System "KREB"
The "KREB" mobile dome protection system is designed to prevent unauthorized UAV flights, shield radio frequencies, and block video and telemetry channels of third-party devices. The complex is designed in the form of a car roof box, which is installed on the car roof, thus maintaining mobility and aerodynamics.
The system consists of a set of active interference generation modules operating in different frequency ranges, creating a dense protective dome. Installed on a vehicle, the complex allows for separate control of each range directly from the vehicle's cabin.
