AH-6090-15

The AH-6090-15 is a professional-grade, high-gain Circular Polarized Helical Antenna engineered for the 6000–9000 MHz (6–9 GHz) frequency range. Delivering a potent 15 dBic gain, this directional aperture is a specialized tool for C-band and X-band applications, including satellite telemetry, tactical data links, and UAV command. By utilizing advanced helical winding technology, the AH-6090-15 provides superior signal "punch-through" in high-interference zones, offering a much higher gain and narrower beamwidth than standard microwave antennas in a significantly more compact form factor.

Battlefield Durability: Built to survive the most punishing environmental extremes

The AH-6090-15 is enclosed in a high-strength fiberglass radome that protects the precision copper radiating elements from physical impact, ice loading, and corrosive atmospheres. Utilizing a 6061T6 aluminum alloy reflector and marine-grade stainless steel mounting hardware, this antenna maintains structural integrity in winds up to 200 Km/Hr and is fully resistant to salt fog and tropical fungus as per MIL-STD-810G protocols.

Operational Efficiency: Maximum power projection and signal integrity 

By securing the high-purity enameled copper winding directly to the radome wall, the AH-6090-15 minimizes internal RF inter-modulation and ensures precise phase alignment. Its focused 30-degree beamwidth and exceptional 24 dB Front-to-Back ratio concentrate RF energy exactly where it is needed, maximizing link distance and signal-to-noise ratio while preventing interference with friendly systems located behind the aperture.

Technical Features

• High Gain Performance: Delivers a typical gain of 15 dBic for long-range microwave links.
• Ultra-Wideband: Operates across the full 6–9 GHz spectrum without field tuning.
• Circular Polarization: Available in RHCP or LHCP to eliminate Faraday rotation and mitigate multipath fading.
• Tactical Steering: Supplied with a mounting arrangement for 360° Azimuth and 90° Elevation tracking.
• Stacking Option: Can be supplied in dual or quad configurations for even higher gain requirements.
• Compact SWaP: Only 220 mm in length and 500 grams (flange mount), optimizing size and weight for mobile masts.

Strategic EW, SIGINT & Monitoring Compatibility

• Electronic Warfare (EW): Acts as a precision directional jammer for high-frequency data links, utilizing circular polarization to bypass linear anti-jam filters.
• Signals Intelligence (SIGINT): The narrow 30-degree beamwidth facilitates accurate emitter triangulation and the interception of weak, long-range microwave telemetry.
• Persistent Monitoring: Serves as a high-fidelity "tripwire" for discovering and characterizing rogue emitters in the C/X-band window.

Global & Environmental Compliances

• MIL-STD Hardening: Fully compliant with MIL-STD-810G standards for High/Low Temperature, Humidity, Shock, Vibration, Rain, and Salt Fog.
• RoHS & REACH: Manufactured using eco-friendly materials, free from restricted hazardous substances and compliant with EU chemical safety registrations.
• WEEE Directive: Supports high-end lifecycle management with recyclable aluminum and copper components.
• CE Certified: Meets all European Union safety, health, and environmental protection requirements.

Key Advantages

• Multipath Immunity: Inherently rejects reflected signals, providing a clean link in tunnels and urban canyons.
• Superior Form Factor: Smaller and more rugged than conventional X-band Yagi or parabolic dish antennas.
• High Front-to-Back Isolation: 24 dB ratio ensures maximum signal purity and reduced background noise intercept.
• Zero Field Tuning: Factory-tuned for immediate "plug-and-play" deployment.

Key Applications

• UAV Ground Control: High-reliability directional command and control links for tactical drones.
• Satellite Telemetry: High-gain Ground-to-Space links for X-band satellite constellations.
• Tunnel Communications: Providing uninterrupted wireless links in high-reflection subterranean military and industrial networks.
• Microwave Backhaul: Establishing secure, long-range point-to-point data bridges across hostile terrain.
