| AH-850 | High Gain Circular Polarized Helical Antenna | 700-990MHz | 12 dBic. |  |  |  |
The AH-850 is a professional-grade Circular Polarized LHCP/RHCP Helical Antenna specifically engineered for the 700–1000 MHz spectrum. Delivering a robust 12 dBic gain, this directional aperture is optimized for mission-critical UAV/drone communications, satellite links, and terrestrial data bridges. By utilizing advanced helical winding technology, the AH-850 provides superior penetration through obstructions and a significant reduction in multipath interference, outperforming larger, conventional Yagi antennas in high-density RF environments.
Logistical Agility: Engineered for rapid global deployment & field integration
The AH-850 is supplied fully assembled with a specialized mounting bracket, reducing field setup time and allowing tactical units to reach operational status immediately without complex calibration.
Battlefield Durability: Built to survive the most punishing environmental extremes
The antenna systems are engineered to exceed the rigorous requirements of MIL-STD-810G, utilizing aerospace-grade 6063T6 aluminum alloy and high-strength fiberglass or ABS radomes to shield sensitive internal radiators. The integration of marine-grade Type 316 stainless steel fasteners and specialized epoxy powder coatings provides total immunity to salt fog, UV degradation, and chemical exposure. With wind ratings frequently reaching 200 Km/Hr and a wide operational temperature range from -30°C to +70°C, these systems maintain structural integrity and electrical performance in everything from arctic freezes to arid desert combat zones.
Operational Efficiency: Maximum power projection and signal integrity
Efficiency (12dBi Gain) is driven by precision-engineered internal components, such as high-purity copper radiators and low-loss Teflon insulators, which minimize internal heat dissipation and maximize RF output. Advanced techniques like coaxial stubs and "Choke and Spark Gap" designs ensure a smooth VSWR and constant gain across ultra-wide bandwidths, allowing a single antenna to replace multiple legacy units. This consolidation not only reduces the overall RF and visual signature of the platform but also ensures that every watt of transmitter power is effectively projected into the theater to maintain dominant communication or jamming links.
Strategic EW, SIGINT & Monitoring Compatibility
- Electronic Warfare (EW): Primary tool for high-power signal denial and spoofing. The high wattage capacity and specialized polarization (Circular or Linear) ensure that jamming energy effectively penetrates modern anti-jam receivers.
- Signals Intelligence (SIGINT): The directional high-gain profiles and clean noise floors allow for the interception of long-range telemetry and weak tactical signals. Narrow beamwidths facilitate precise signal characterization and emitter triangulation.
- Persistent Monitoring: Provides 360-degree horizontal situational awareness, acting as a persistent electronic "tripwire" for theater dominance and early warning signal discovery.
Global & Environmental Compliances
- MIL-STD Hardening: Fully compliant with MIL-STD-810G protocols, covering High/Low Temperature, Shock, Vibration, Humidity, Salt Fog, and Rain tests to ensure mission-readiness in any theater.
- RoHS Compliant: Strict adherence to the restriction of hazardous substances, ensuring lead-free and eco-friendly electronic components.
- REACH & WEEE: Full compliance with EU chemical safety registrations and high-end lifecycle management directives for the sustainable disposal of aluminum and copper materials.
- CE Mark: Certified to meet all European Union safety, health, and environmental protection requirements.
Key Advantages
- Unified Bandwidth: Single-antenna footprints replace complex legacy arrays, significantly reducing platform weight and RF signature.
- Polarization Dominance: Circularly polarized models (RHCP/LHCP) virtually eliminate Faraday rotation and multipath fading in urban or tunnel environments.
- Zero Field Tuning: Factory-tuned architectures ensure immediate "plug-and-play" tactical deployment without the need for manual calibration.
- High Power Density: Capable of handling sustained RF transmission up to 500W (or 1KW optional) for persistent wide-area protection.
Key Applications
- C-UAS & RCIED Defeat: Disruption of drone command links and neutralizing remote-controlled improvised triggers.
- Satellite Telemetry: High-gain Ground-to-Space links for L-band and S-band satellite constellations.
- Tunnel Communications: Providing reliable wireless links in high-reflection subterranean military and industrial networks.
- Convoy Protection: Creating a mobile electronic shield for tactical units, EOD teams, and VIP motorcades.
Design Features: The AH-850 uses extended stubs to provide the greater gain while maintaining the wider beam-width. This high-gain low-profile antennas use Circular Polarization Antenna Technology - which delivers better penetration through obstruction and interference. This commercial grade antenna provides superior performance as compare to significantly larger and more expensive products. Our AH series helical antennas are smaller than conventional yagi antenna. The AH-850 Helical Antenna is supplied with a specially designed mounting arrangement for steering the antenna in both planes, over 360 Degrees in Azimuth and 90 Degrees in Elevation for terrestrial and satellite links.
