The HR-1575-5 is a professional-grade, Linear Polarized GPS L1 Band Horn Antenna specifically engineered for the 1550–1590 MHz frequency range. This directional aperture is optimized for high-precision GPS L1 signal reception, persistent monitoring, and tactical jamming applications. Featuring a compact, low-profile design and a ruggedized fiberglass radome, the HR-1575-5 offers a specialized solution for platforms requiring directional S-band dominance in a lightweight, maintenance-free form factor.
Design: Wide-Angle Directional Precision
The HR-1575-5 is optimized for mission-critical hubs that require directional signal projection or intercept without the extreme narrowness of high-gain parabolic dishes.
- Wider Sectoral Coverage: Delivering a wide 120-degree 3dB beamwidth, this antenna provides substantial sectoral coverage, making it ideal for monitoring multiple satellite links or saturating a broad area with jamming signals.
- 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 depth of only 120 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 L1 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 S-band signals and satellite telemetry.
- Persistent Monitoring: The directional pattern provides high-gain sectoral surveillance, acting as a focused electronic "tripwire" for theater awareness.
Global Compliances & MIL-STD Hardening
The HR-1575-5 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
- Unified GPS L1 Solution: Optimized for the 1575.42 MHz center frequency while covering the entire 1550–1590 MHz band.
- 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.
Key Applications
- GPS L1 Jamming/Spoofing: Focused denial of satellite-based navigation and timing signals.
- Satellite Telemetry Intercept: High-fidelity reception of low-power S-band data links.
- Sectoral Surveillance: Persistent monitoring of specific 120-degree sectors for EW situational awareness.
- C-UAS Operations: Targeted disruption of drone GNSS/GPS navigation systems.
Design Features : The HR-1575-5 horn antenna uses 6063T6 ultra corrosion resistant architectural anodized aluminum alloy and designed to provide wideband directional transmission/reception of radio signals from 1550-1590 MHz bands including GPS L1 bands. This low-profile horn antenna uses Linear Polarization Antenna Technology - which can be changed in the field from Vertical to Horizontal and vice versa. This commercial grade horn antenna provides medium performance while maintaining the wider beam-width as compare to significantly larger and more expensive products. The specially designed mounting arrangement results in fast installation. The horn antenna is supplied complete in assembled condition. This horn antenna system is particular suitable for transmission, reception, monitoring, scanning and jamming applications due to its broad band design feature.
