JCM6-1216

The JCM6-1216 is a high-performance Broadband Manpack Jammer Collinear Antenna specifically engineered for the 1200–1600 MHz (1.2–1.6 GHz) spectrum. This unified aperture is a critical tactical asset for the simultaneous denial of multiple satellite-based navigation and timing signals, including GPS L1, GPS L2, GLONASS, and Galileo bands. By delivering a concentrated 6 dBi peak gain and an exceptional 150W power handling capacity in a compact 350 mm form factor, it provides dismounted Electronic Warfare (EW) teams with a versatile, high-intensity solution for GNSS signal suppression.

Design: Unified GNSS Spectrum Mastery

The JCM6-1216 is designed for operators who require "zero-gap" protection across the L-band GNSS spectrum without carrying multiple antennas.

• Broadband Dual-Band Coverage: This antenna provides a unified solution for the entire 400 MHz bandwidth. It ensures consistent protection against both military L2 (1227.6 MHz) and civilian/military L1 (1575.42 MHz) satellite downlinks.
• Exceptional 150W Power Handling: Built to sustain continuous-duty, high-power electronic attack missions, the JCM6-1216 manages up to 150 Watts of RF throughput. This allows for massive signal saturation to overcome anti-jamming GNSS receiver logic.
• Optimized 35° Vertical Beamwidth: The antenna focuses its radiation into a 35-degree vertical beam. This directs the jamming energy toward the horizon, maximizing the effective Jamming-to-Signal (J/S) ratio where ground-based or low-altitude receivers are located.
• Direct Transmitter Integration: Featuring an N-Male termination, the antenna mounts directly onto the equipment. This eliminates lossy coaxial cables, ensuring every watt of jamming power reaches the aperture.

Construction: Hardened Tactical Architecture

Built for the rigors of modern theater, the JCM6-1216 is a "zero-tuning" tactical asset designed for immediate deployment.

• Aerospace-Grade Materials: Utilizing 6063T6 ultra-corrosion-resistant aluminum alloy for radiating elements and Teflon/Nylon insulators, the antenna maintains electrical stability under extreme RF thermal loads.
• Ultra-Compact & Agile: At only 350 mm (13.7 inches) and 500 grams, it provides an elite power-to-size ratio, minimizing the physical footprint and snagging risk for dismounted foot patrols.
• Rugged ABS Radome: The internal architecture is protected by a high-strength ABS radome, finished in Olive Green (RAL6003). This housing is UV-stabilized and RF-transparent, shielding the system from ice, sand, and moisture.

Technical Features
