JC3-2025

The JC3-2025 is a professional-grade, ultra-compact S-Band Jammer Collinear Antenna specifically engineered for the 2000–2500 MHz spectrum. Optimized for both man-portable (man-pack) and vehicular mounting, this ruggedized aperture provides a unified solution for high-power signal denial and electronic protection in the critical 2.4 GHz ISM band. Delivering a consistent 3 dBi gain in an exceptionally lightweight 200-gram form factor, the JC3-2025 ensures mission-critical performance for elite tactical units.

Design: SWaP-Optimized S-Band Dominance

The JC3-2025 is designed with a focus on SWaP (Size, Weight, and Power) requirements, making it one of the most agile antennas in the S-band category.

• Tactical Portability: At just 210 mm (8.3 inches) in length and weighing only 200 grams, it minimizes the physical burden on dismounted soldiers while maintaining the electrical performance of larger arrays.
• In-Phase Collinear Architecture: Large-diameter brass radiating elements are stacked vertically and fed in-phase to project a consistent omnidirectional pattern. The 38-degree vertical beamwidth ensures a reliable "denial bubble" around the operator or vehicle.
• Stable VSWR: Utilizes specialized co-axial stub and spark gap techniques to maintain a smooth VSWR of 2:1 across the entire 500 MHz bandwidth without any field tuning.

Construction: Tactical Hardening & Multi-Platform Agility

Built to survive 24/7 exposure in the world's most punishing combat environments.

• High-Strength Fiberglass Radome: The radiating core is fully protected by a 44 mm diameter fiberglass enclosure. This material offers excellent RF transparency and superior mechanical robustness to withstand physical impact and environmental stress.
• Military-Grade Materials: Features high-class aluminum alloy support structures and all-brass internal radiators, ensuring a quiet signal path and maximum electrical efficiency.
• Modular Mounting: Specifically designed for roof-top hole installation on vehicles, direct mounting onto jammer equipment for man-pack use, or optional pole mounting for fixed-site base stations.
• MIL-SPEC Aesthetics: Supplied in Military Olive Green to maintain a low visual signature for covert and tactical operations.

Key Technical Characteristics

• Extreme 250W Power Capacity: One of the few ultra-compact antennas capable of managing 250 Watts of continuous-duty RF transmission.
• Wide Frequency Agility: Continuous coverage from 2000 to 2500 MHz, neutralizing threats in the high-frequency cellular and Wi-Fi bands.
• High Wind Stability: Aerodynamic profile rated for structural integrity in winds up to 200 Km/Hr.
• Environmental Tolerance: Operational from -30°C to +70°C, ensuring performance in arctic freezes or desert heat.
• Zero Maintenance: Factory-tuned architecture requires no periodic calibration or field adjustments.

EW, SIGINT & Monitoring Compatibility

• Electronic Warfare (EW): Primary defense against S-band RCIED triggers and high-power signal denial.
• Counter-UAS (C-UAS): Specifically designed to disrupt 2.4 GHz UAV command and video telemetry links.
• Signals Intelligence (SIGINT): The clean noise floor and stable gain allow for high-speed spectrum scanning and discovery of microwave tactical networking.
