Remote Antenna Module (RAM) 3m Universal for "Chuyka" by BlueBird is a professional solution from the manufacturer BlueBird for electronic reconnaissance (SIGINT). The RAM Universal platform is designed as a modular, all-weather, high-performance system, optimized to ensure maximum efficiency and stability of the "CHUYKA" SIGINT complex and compatible with other electronic systems in the relevant frequency ranges.
Thanks to its universal design and standardized interfaces, RAM Universal allows the antenna-feeder equipment to be moved away from the operator, which improves reception quality, reduces the impact of local interference, and expands coverage. The module's casing is shock-resistant and has a high degree of protection against atmospheric influences, dust, and vibrations, ensuring reliable operation of the three integrated antennas during rapid deployment and long-term use.
Technical Features and Adaptability
Modularity of Feeder Lines
The Universal version is equipped with industrial N-type female connectors on the casing, allowing the operator to choose and quickly change the length and type of coaxial cable to minimize signal loss over the required distance.
Reliable Design and Protection
The casing provides protection for the three integrated antennas from precipitation, dust, and mechanical impacts. The design is engineered for field operation, guaranteeing resistance to vibrations and shocks during transportation and deployment.
Three-Channel Integration
RAM Universal has three independent antenna channels, identical to those used in the base "CHUYKA" SIGINT device, which guarantees predictable reception characteristics in the following ranges:
- Channel 1: 1080–1800 MHz
- Channel 2: 3000–4100 MHz
- Channel 3: 4900–6100 MHz
Universal Mounting and Deployment
The module is equipped with four powerful magnets for instant fixation on metal surfaces. For stationary mounting, two mounting holes (56 mm between centers) are provided for secure attachment to a mast or pipe using a U-bolt (supplied in the kit). Additional technological holes allow the use of cable ties or other fastening means on atypical surfaces (wood, structures).
Global Compatibility
Thanks to standard connectors and a cable assembly with SMA-male connectors, RAM Universal easily integrates with any electronic equipment with SMA-female inputs operating in the specified frequency ranges.
