HR-1227-5

The HR-1227-5 is a professional-grade, Linear Polarized GPS L2 Band Horn Antenna specifically engineered for the 1210–1240 MHz frequency range. This directional aperture is optimized for high-precision GPS L2 signal reception, persistent monitoring, and tactical jamming applications. Featuring a compact, low-profile design and a ruggedized fiberglass radome, the HR-1227-5 offers a specialized solution for platforms requiring directional L-band dominance in a lightweight, maintenance-free form factor.

Design: Wide-Angle Directional Precision

The HR-1227-5 is optimized for mission-critical hubs that require directional signal projection or intercept without the extreme narrowness of high-gain parabolic dishes.

• Wide Sectoral Coverage: Delivering a substantial 120-degree 3dB beamwidth, this antenna provides a broad "Denial Zone" or monitoring field, making it ideal for saturating a wide area with jamming signals or monitoring multiple L-band satellite links.
• Field-Adjustable Polarization: Utilizing advanced linear polarization technology, the antenna can be oriented for Vertical or Horizontal polarization in the field. An optional dual-linear configuration is available to support simultaneous V & H reception for polarization diversity.
• Low-Profile Aperture: With a compact 120 x 120 mm aperture and a shallow radome depth of only 125 mm, it offers a significantly smaller footprint than traditional horn antennas, reducing wind loading and visual signature.

Construction: Environmental Resilience

Built for survivability in the world’s most punishing theaters, from high-salinity coastal zones to high-intensity combat operations.

• Aerospace-Grade Materials: Constructed using 6063T6 ultra-corrosion resistant architectural anodized aluminum alloy and high-quality internal brass radiators. The entire assembly is finished with an epoxy-based powder coating for maximum UV and chemical protection.
• Protective Fiberglass Radome: The aperture is fully enclosed in a fiberglass radome, ensuring the internal radiating elements are shielded from driving rain, ice accumulation, and physical debris while maintaining peak RF transparency.
• Marine-Grade Hardware: All assembly fasteners, including screws, nuts, and bolts, are made of Type 316 marine-grade stainless steel for total immunity to corrosive gases and salt spray.

EW, SIGINT & Monitoring Compatibility

• Electronic Warfare (EW): Primary tool for GPS L2 navigation denial and signal spoofing. The 100W power handling and 15 dB front-to-back ratio ensure that jamming energy is focused on the target while protecting friendly systems behind the antenna.
• Signals Intelligence (SIGINT): The clean noise floor and stable VSWR (better than 1.5:1) allow for high-fidelity intercept of weak L-band satellite telemetry and data links.
• Sectoral Surveillance: The directional pattern provides high-gain sectoral surveillance, acting as a focused electronic "tripwire" for theater awareness.

Global Compliances & MIL-STD Hardening

The HR-1227-5 is engineered for survivability in the world's most hostile environmental theaters:

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

Key Advantages

• Optimized for GPS L2: Precision factory tuning for the 1227.60 MHz center frequency and adjacent L-band spectrum.
• Directional Isolation: 15 dB front-to-back ratio ensures maximum signal purity and prevents interference from rear-located emitters.
• Rapid Tactical Setup: Supplied in a complete, assembled condition with a universal mounting clamp for up to 2-inch (52mm) pipes.
• High-Power Capacity: Handles up to 100 Watts of continuous-duty RF transmission.
• Ultra-Lightweight: Weighs less than 2 Kgs, making it suitable for quick-deploy tactical masts and man-portable kits.
