| AH-600 | High Gain Circular Polarized Helical Antenna | 500-700 MHz | 12 dBic |  |  |  |
The AH-600 is a professional-grade Circular Polarized LHCP/RHCP Helical Antenna precision-engineered for the 500–700 MHz frequency range. Delivering a robust 12 dBic gain, this directional aperture is a specialized tool for UHF tactical communications, satellite telemetry, and persistent link stability in high-interference zones. By utilizing advanced helical winding technology, the AH-600 provides superior signal "punch-through" and effectively eliminates multipath interference, offering a more compact and rugged alternative to traditional linear Yagi arrays.
Battlefield Durability: Built to survive the most punishing environmental extremes
The AH-600 is encased in a high-strength fiberglass radome that protects the precision copper radiating elements from physical impact, ice loading, and corrosive atmospheres. Utilizing stainless steel mounting hardware and an aerodynamic cylindrical enclosure, this antenna maintains structural integrity in winds up to 190 Km/Hr and extreme thermal cycles from -30°C to +70°C.
Operational Efficiency: Maximum power projection and signal integrity
Efficiency is maximized by utilizing high-purity copper radiating elements and a factory-tuned architecture that ensures a stable 1:2.0 VSWR across the entire 200 MHz bandwidth. Its focused 40-degree beamwidth and 15 dB Front-to-Back ratio ensure that the 250W of RF power is concentrated exactly where it is needed, significantly extending the effective standoff distance while preventing interference with friendly systems located behind the aperture.
Technical Features
- High-Gain Performance: Delivers a typical gain of 12 dBic for long-range UHF link stability.
- Array Scalability: Can be supplied in DUAL (AH-600D) or QUAD stacked configurations for even higher gain and wider beamwidth requirements.
- Circular Polarization: Available in LHCP or RHCP to virtually eliminate Faraday rotation and minimize multipath interference.
- Tactical Steering: Supplied with a specialized mounting arrangement for 360° Azimuth and 90° Elevation tracking.
- Compact Form Factor: Significantly smaller and more rugged than conventional linear UHF antennas of equivalent gain.
- Low Wind Loading: Cylindrical enclosure design reduces drag and prevents ice accumulation in cold-weather theaters.
Strategic EW, SIGINT & Monitoring Compatibility
- Electronic Warfare (EW): Acts as a high-intensity polarization-matched jammer for UHF data links, utilizing circular polarization to bypass linear anti-jam filters.
- Signals Intelligence (SIGINT): The clean noise floor and 12 dBic gain allow for the interception of weak, long-range telemetry and tactical UHF signals.
- Persistent Monitoring: Serves as a high-fidelity electronic "tripwire" for situational awareness in high-reflection environments like urban canyons or metallic corridors.
Global & Environmental Compliances
- MIL-STD Hardening: Designed to meet rigorous military protocols for Temperature, Humidity, Shock, and Vibration.
- RoHS & REACH: Constructed with eco-friendly, lead-free components 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 urban or subterranean networks.
- High Power Capacity: Handles up to 250 Watts of continuous-duty RF transmission.
- High Front-to-Back Isolation: 15 dB ratio minimizes background noise intercept and "back-lobe" interference.
- Zero Field Tuning: Factory-tuned for immediate "plug-and-play" deployment.
Key Applications
- Tactical UHF Links: High-reliability directional command and control in the 500-700 MHz window.
- Satellite Telemetry: High-gain Ground-to-Space links for LEO satellite constellations.
- Array Formations: Customizable gain profiles for specialized Electronic Attack (EA) and signal intercept missions.
- Point-to-Point Bridges: Establishing high-capacity, long-range data links across hostile terrain.
Design Features: The AH-600 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-600 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.
