JC-25-66

The JC-25-66 is a professional-grade VHF Fiberglass Jammer Collinear Antenna specifically engineered for the critical 25–66 MHz tactical spectrum. This ruggedized, vertically polarized aperture is designed to provide persistent wideband electronic protection for mobile assets and tactical convoys. By utilizing vertically stacked brass radiating elements and a standardized NATO mounting interface, the JC-25-66 delivers 360-degree situational awareness and high-power signal denial in a maintenance-free, field-proven form factor.

Design: Tactical VHF Dominance & Mobile Integration

The JC-25-66 is optimized for "On-The-Move" (OTM) missions requiring persistent electronic protection across a broad 40 MHz bandwidth. Its collinear design features vertically stacked, in-phase radiating elements that project a consistent omnidirectional pattern toward the horizon. The wide 78-degree vertical beamwidth is a critical tactical advantage, ensuring that jamming energy remains effective even when the vehicle is traversing uneven, rugged, or mountainous terrain. With a specialized "Co-axial Stub and Spark Gap" architecture, the antenna maintains stable electrical performance and a smooth VSWR without requiring manual field tuning.

Construction: MIL-SPEC Hardening & Structural Integrity

Built for the rigors of frontline combat, the antenna is fully enclosed in a high-strength Cylindrical Fiberglass Radome (44 mm diameter). This enclosure offers superior RF transparency while protecting the internal brass elements from physical impact, UV radiation, and heavy ice accumulation. All support structures are crafted from high-class aluminum alloy, and the system is finished in Military Olive Green to maintain a low visual signature. The N-Female termination is strategically housed within the NATO mounting base, providing 360-degree weather protection for the critical RF signal path.

Compatibility: EW, SIGINT & Global Monitoring

The JC-25-66 serves as a high-fidelity multi-mission hub for specialized electromagnetic operations:

• Electronic Warfare (EW): Engineered to handle 150 Watts of continuous-duty RF power for wide-area denial of adversary tactical voice and data nets in the lower VHF bands.
• SIGINT & Spectrum Monitoring: The use of large-diameter brass radiating elements ensures a quiet, PIM-free signal path, making it an elite tool for high-fidelity signal discovery and intercept.
• Global Compliances: Fully designed and tested to meet stringent military standards for environmental resilience:
  • High Thermal Tolerance: Operational from -30°C to +70°C, covering all global theaters.
  • Vibration & Shock Hardened: Specifically designed for side-mounting on military vehicles using standard NATO adaptor base plates.
  • Wind Stability: Aerodynamic profile rated for structural integrity in winds up to 170 Km/Hr.

Key Technical Characteristics

• Broad Frequency Agility: Covers 25–66 MHz, a primary band for tactical RCIED triggers and low-band military communications.
• NATO Interface Ready: Equipped with a standard NATO 4-hole pattern base for immediate installation on armored personnel carriers (APCs), command vehicles, and tactical trucks.
• Rugged All-Weather Build: Fiberglass housing resists corrosion in saline coastal environments and sand abrasion in desert theaters.
• Optimized Vertical Aperture: 78-degree beamwidth provides superior coverage for ground-to-ground and ground-to-air links.
• Zero Maintenance: Rugged all-weather construction requires no periodic calibration or adjustments.
