JC7-1575

The JC7-1575 is a professional-grade, Omni-Directional High Gain Jammer Collinear Antenna specifically engineered for the 1550–1590 MHz frequency range. Delivering a consistent 7 dBi gain, this tactical aperture is optimized for neutralizing GPS L1 signals and disrupting high-speed data links within the upper L-band. Featuring a ruggedized ABS radome and versatile mounting configurations, the JC7-1575 provides persistent electronic protection for military vehicles, man-packs, and fixed-site installations.

Design: Precision GPS L1 Band Dominance

The JC7-1575 is optimized for mission-critical Electronic Warfare (EW) hubs requiring a potent "Denial Zone" against satellite-based navigation and timing.

• High-Efficiency Collinear Build: By utilizing vertically stacked, high-quality radiating elements, the antenna achieves a narrow 36-degree vertical beamwidth. This concentrates RF energy toward the horizon, maximizing the effective jamming radius against ground-based receivers and low-altitude aerial assets.
• Superior Impedance Matching: Engineered to maintain an exceptional VSWR of better than 1.5:1 across the entire bandwidth, ensuring maximum power transfer and protecting sensitive transmitter hardware from reflected power.
• Aero-Dynamic Profile: The cylindrical enclosure is designed for low wind loading (200 Km/Hr rating) and minimal ice formation, ensuring stable performance in extreme climates.

Construction: Tactical Versatility & Hardening

Built for 24/7 survivability in frontline combat environments, the JC7-1575 offers the most flexible mounting suite in its class.

• Ruggedized ABS Radome: The radiating core is fully enclosed in a high-strength 45 mm diameter ABS radome. This material provides excellent RF transparency and superior mechanical robustness to withstand physical impact and UV degradation.
• Corrosion-Resistant Materials: Constructed from 6063T6 ultra-corrosion resistant aluminum alloy, the radiators and support pipes are finished in Military Olive Green for a low visual signature.
• Five Tactical Mounting Options:
  1. Standard NATO 4-Hole: For armored vehicle integration.
  2. Roof-Top Hole (16mm): For discreet vehicular installation with N-Female termination.
  3. Direct Man-Pack: Optimized for dismounted equipment with M-Male termination.
  4. Pole Mount: Suitable for fixed-site pipes between 32–51mm.
  5. Shock-Absorbing NATO Mount: Equipped with a bi-conical spring to absorb high-intensity vibrations during off-road maneuvers.

EW, SIGINT & Monitoring Compatibility

• Electronic Warfare (EW): Primary tool for GPS L1 navigation denial and signal spoofing.
• Counter-UAS (C-UAS): Specifically designed to disrupt the GNSS/GPS navigation systems of tactical drones.
• Signals Intelligence (SIGINT): The clean noise floor and stable gain allow for high-fidelity intercept of L-band satellite telemetry and data links.
• Theater Awareness: The 360-degree horizontal coverage ensures total situational dominance for early warning systems.

Key Advantages

• 7 dBi High Gain: Provides an extended protective "bubble" compared to standard low-gain whips.
• 150W Power Capacity: Handles high-intensity, continuous-duty RF transmission for sustained jamming.
• Multi-Platform Agility: Can be transitioned from a vehicle to a man-pack or base station in minutes.
• Zero Field Tuning: Fully factory-tuned for immediate "plug-and-play" deployment.
• Compact SWaP Profile: 500 mm length and 1 Kg weight make it ideal for weight-sensitive tactical platforms.
