JCM9-1850

The JCM9-1850 is an elite High Gain Manpack Jammer Collinear Antenna specifically engineered for the 1800–1870 MHz (1.8 GHz) GSM band. Optimized for dismounted Electronic Warfare (EW) and cellular denial, this antenna delivers a massive 9 dBi gain in a 650 mm form factor. By utilizing precision-stacked brass radiating elements, it provides a surgical electronic shield against GSM-based triggers and high-speed data links, ensuring maximum standoff safety for tactical teams.

Design: Precision Range & GSM Band Mastery

The JCM9-1850 is designed for operators who require maximum power density to neutralize localized GSM nodes and cellular-based threats.

• Elite 9 dBi Omni Gain: Achieving 9 dBi in a portable configuration allows for a massive expansion of the "safety bubble." This gain level focuses energy horizontally to establish a dominant Jamming-to-Signal (J/S) ratio against distant cellular towers.
• Surgical 18° Vertical Beamwidth: The antenna compresses the signal into a thin, powerful 18-degree vertical beam. This ensures that the 50W of transmitter power is directed toward the horizon where threats are located, rather than wasting energy on the sky or ground.
• Direct N-Male Integration: The antenna mounts directly onto the equipment's RF port. For high-mobility missions, the JCM9-1850-S version with a spring base is available to absorb mechanical shocks and protect the radio's interface.

Construction: Combat-Tier Hardening

Built for the rigors of modern field operations, the JCM9-1850 is a "zero-tuning" tactical asset designed for rapid deployment.

• Ultra-Lightweight & Agile: At only 350 grams and 650 mm long, it minimizes physical fatigue while providing the performance of a much larger aperture.
• Premium Radiating Elements: High-quality brass radiating elements and 6063T6 aluminum alloy components ensure high conductivity and ultra-corrosion resistance.
• ABS Radome Resilience: The 25 mm diameter ABS radome is UV-stabilized and RF-transparent, shielding the internal architecture from ice, sand, and moisture without signal degradation.
