JC5-1216

The JC5-1216 is a professional-grade, Omni-Directional GPS Jammer Collinear Antenna specifically engineered for the 1200–1600 MHz spectrum. This unified L-band aperture is a critical asset for Electronic Warfare (EW) units, providing a single-antenna solution for neutralizing both GPS L1 and GPS L2 bands. Featuring a compact 400 mm profile and extensive MIL-STD-810G hardening, the JC5-1216 is designed for persistent electronic protection across shipboard, fixed-station, and tactical mobile platforms.

Design: Dual-Band GNSS Denial

The JC5-1216 is optimized for mission-critical hubs that require simultaneous suppression of multiple satellite navigation frequencies.

• Unified Spectrum Access: Replaces the requirement for multiple antennas by covering the entire 1200–1600 MHz range, effectively denying GPS, GLONASS, and Galileo signals.
• Anti-Intermodulation Architecture: All internal radiating elements are fully welded to their appropriate locations. This prevents RF inter-modulation and ensures signal purity during high-power transmission.
• Optimized Vertical Aperture: A 40-degree vertical beamwidth provides a wide terrestrial "denial bubble," ensuring that jamming energy reaches ground-based receivers even during vehicle pitch or sea-state oscillations on shipboard mounts.

Construction: Tactical Hardening & Materials

Built for survivability in the most punishing environmental theaters, from high-salinity coastal zones to arid desert combat.

• High-Strength ABS Radome: The radiating core is fully enclosed in a 45 mm diameter UV-resistant ABS radome. This material offers excellent RF transparency while providing the mechanical robustness required to withstand physical impact and high wind loads (180 Km/Hr).
• Aerospace-Grade Materials: Constructed using 6063T6 ultra-corrosion resistant aluminum alloy and high-quality internal radiating elements. The assembly is finished in Military Green powder coating for maximum environmental protection.
• Precision Insulation: Utilizes Teflon and Nylon insulators to maintain electrical integrity under high RF power (150 Watts) and extreme thermal cycles

Strategic EW, SIGINT & Monitoring Compatibility: JC5-1216

The JC5-1216 is a specialized wideband tactical asset designed for comprehensive L-band electromagnetic operations. By covering the 1200–1600 MHz range with a single high-power aperture, it provides a unified solution for Electronic Warfare (EW), Signals Intelligence (SIGINT), and persistent Spectrum Monitoring across the entire GNSS (Global Navigation Satellite System) spectrum.

1. Electronic Warfare (EW) & Electronic Attack (EA)

In Electronic Attack missions, the JC5-1216 acts as a Multi-Band GNSS Denial Hub. Its architecture is specifically hardened for the extreme thermal and electrical stresses of continuous-duty jamming.

• Unified GPS L1 & L2 Neutralization: Engineered to simultaneously deny both L1 (1575.42 MHz) and L2 (1227.60 MHz) bands. This is critical for neutralizing modern military-grade and multi-frequency civilian GNSS receivers.
• High-Intensity Power Projection: With a 150W CW rating, this antenna can project a potent "denial bubble," saturating the environment to protect convoys from GPS-guided loitering munitions or drone incursions.
• Anti-Intermodulation Design: All radiating elements are fully welded to ensure signal purity, preventing the generation of unwanted interference (PIM) during high-power signal denial operations.

2. Signals Intelligence (SIGINT) & Electronic Support (ES)

For SIGINT operators, the JC5-1216 is a high-fidelity L-Band Discovery Tool. Its stable VSWR and clean noise floor are essential for modern digital intercept receivers.

• Full L-Band Spectrum Scanning: The antenna maintains a consistent 5 dBi gain across its 400 MHz bandwidth, allowing automated SIGINT systems to scan for satellite telemetry, encrypted data links, and low-power beacons without "blind spots."
• 360-Degree Theater Awareness: Provides total horizontal situational awareness, acting as a primary electronic "tripwire" to alert operators to new emitters across the 1.2–1.6 GHz window.
• Precision Signal Path: The use of 6063T6 aluminum and Teflon/Nylon insulators ensures an ultra-clean signal path for detecting weak L-band transmissions.

Global Compliances & MIL-STD Hardening

The JC5-1216 is rigorously tested to MIL-STD-810G protocols, ensuring operational survivability in front-line combat and maritime zones:

Key Advantages

• All-in-One GNSS Solution: Replaces the need for separate L1 and L2 antennas, significantly reducing the RF footprint and weight on tactical platforms.
• Rigid Battlefield Durability: The 400 mm compact length and rigid mount eliminate the need for complex spring bases, providing maximum structural stability in high-vibration environments.
• Continuous Duty Power: Capable of sustained 150W transmission, making it a "force multiplier" for persistent electronic protection.
• Weather-Shielded Termination: The N-Female connector is recessed at the bottom of the mounting flange, protecting the critical RF link from environmental exposure.
• Zero Field Tuning: Factory-tuned architecture ensures immediate tactical deployment without the need for manual calibration.

Key Applications

• Multi-Band RCIED & GNSS Defeat: Primary defense against triggers and guidance systems utilizing GPS, GLONASS, Galileo, or Beidou frequencies.
• Counter-UAS (C-UAS): Disrupting drone navigation and "Return to Home" (RTH) capabilities by saturating L1 and L2 frequencies.
• Convoy Electronic Protection: High-power shielding for mobile tactical units, EOD teams, and VIP motorcades.
• Shipboard & Naval Defense: Rugged, salt-resistant omni-directional monitoring and jamming for littoral patrol vessels.
• Spectrum Surveillance: Early warning signal discovery and monitoring of L-band satellite telemetry and microwave data links.
