JC8-850

The JC8-850 is a professional-grade, High Gain Jammer Collinear Antenna specifically engineered for the 820–960 MHz spectrum. Delivering a potent 8 dBi gain, this tactical aperture is optimized for neutralizing cellular triggers and disrupting radio communications within the GSM-900 and CDMA-850 bands. Featuring a ruggedized fiberglass radome and a 250W power rating, the JC8-850 is designed for persistent electronic protection across vehicular, man-pack, and fixed-site platforms.

Design: Focused Sub-GHz Spectrum Dominance

The JC8-850 is optimized for mission-critical Electronic Warfare (EW) hubs requiring a potent "Denial Zone" against terrestrial cellular triggers.

• Precision Energy Focusing: By stacking large-diameter brass radiating elements vertically and feeding them in phase, the antenna compresses the vertical beamwidth to a narrow 10 degrees. This concentration of RF energy on the horizon provides a massive 8 dBi gain, significantly extending the effective jamming radius.
• Superior Impedance Matching: Utilizes specialized co-axial stub and spark gap techniques to maintain an exceptional VSWR of 1.5:1 across the entire bandwidth, ensuring maximum power transfer and protecting transmitter hardware from reflected power.

Construction: MIL-SPEC Environmental Hardening

Built for survivability in the world’s most punishing theaters, from arctic freezes to arid desert combat.

• Ruggedized Fiberglass Radome: The internal radiating elements are fully protected by a 32 mm diameter fiberglass housing. This enclosure offers superior RF transparency and mechanical robustness against physical impact, UV radiation, and high-velocity winds (200 Km/Hr).
• Aerospace-Grade Materials: Constructed using high-class aluminum alloy for the support structure and all-brass radiators to ensure electrical longevity and structural integrity.
• Multi-Platform Agility: Specifically designed for vehicle roof-top hole installation, direct mounting onto jammer equipment for man-pack use, or optional pole mounting (up to 52 mm diameter) for fixed-site base stations.

EW, SIGINT & Monitoring Compatibility

• Electronic Warfare (EW): Primary defense against RCIED (Remote Controlled IED) triggers utilizing GSM and CDMA cellular frequencies. The 250W capacity allows for aggressive, continuous-duty jamming.
• Signals Intelligence (SIGINT): The high-gain profile and clean noise floor allow for the interception of weak signals and high-speed spectrum scanning in the sub-GHz range.
• Theater Awareness: The 360-degree horizontal coverage ensures total situational dominance, acting as a persistent electronic "tripwire" for early warning systems.

Global Compliances & MIL-STD Hardening

The JC8-850 is engineered for battle-ready reliability:

• Thermal Tolerance: Operational from -30°C to +70°C, covering all global operational theaters.
• Wind Stability: Aerodynamic profile rated for structural integrity in winds up to 200 Km/Hr.
• Humidity Resilience: 0 to 95% RH rating for tropical and high-salinity maritime environments.

Key Advantages

• Powerful 8 dBi Gain: Provides a significantly larger protective "bubble" compared to standard low-gain vehicular whips.
• 250W CW Power Capacity: Handles high-intensity continuous RF transmission without thermal degradation.
• Unified sub-GHz Solution: Covers 820–960 MHz in a single footprint, neutralizing both GSM and CDMA threats.
• Zero Field Tuning: Factory-tuned architecture ensures immediate tactical deployment.
• Low-Profile Aesthetics: Finished in Military Olive Green for a low visual signature on tactical platforms.

Key Applications

• RCIED Defeat: Mobile jamming to neutralize cellular triggers and protect tactical convoys.
• Cellular Network Denial: Disruption of adversary GSM-900 and CDMA-850 communication nodes.
• Convoy Electronic Protection: Providing an extended-range electronic shield for heavy mobile units.
• Fixed Base Defense: Persistent electronic protection for forward operating bases.
