Overview: AH-1800-16 High-Gain Extended Range Helical Antenna
The AH-1800-16 is a professional-grade Extended Range Circular Polarized Helical Antenna precision-engineered for the 1700–2000 MHz (1.7–2.0 GHz) spectrum. Delivering a potent 16 dBic gain and a 200-Watt power handling capacity, this directional aperture is a premier solution for long-range tactical L-band data links, telemetry, and cellular band monitoring. By utilizing advanced helical winding and circular polarization (RHCP/LHCP), the AH-1800-16 provides unmatched signal "punch-through" and multipath rejection, outperforming traditional linear Yagi antennas in high-interference environments.
Battlefield Durability: Built to survive the most punishing environmental extremes.
The AH-1800-16 is encased in a high-strength, cylindrical ABS radome that shields the precision copper radiating elements from physical impact, ice loading, and corrosive atmospheres. Featuring marine-grade stainless steel hardware and a rugged aluminum reflector, the antenna is built to withstand winds up to 180 Km/Hr. Its resilient design ensures mission-readiness in temperatures ranging from -30°C to +70°C, finished in tactical olive green for low observability.
Operational Efficiency: Maximum power projection and signal integrity
Efficiency is maximized by using high-purity copper radiating elements secured within the radome to prevent geometry shifts and eliminate internal RF noise. Its highly focused 25-degree beamwidth and exceptional 30 dB Front-to-Back ratio ensure that the 200W of RF power is concentrated exactly where it is needed—maximizing effective standoff distance while providing extreme isolation from rearward interference and background ground noise.
Detailed Technical Features
- Extended L-Band Mastery: Seamlessly covers the 1.7–2.0 GHz window, supporting critical tactical and telemetry frequencies.
- High-Gain Directional Output: Provides a consistent 16 dBic gain, outperforming significantly larger and more expensive linear arrays.
- Circular Polarization (CP): Available in RHCP or LHCP to virtually eliminate Faraday rotation and mitigate signal fading.
- Precision Steering Suite: Supplied with a specialized mounting arrangement for 360° Azimuth and 90° Elevation tracking.
- Low VSWR Architecture: Maintains a better than 1.5:1 VSWR across the entire band for maximum power transfer.
- Tactical SWaP Profile: Lightweight design at less than 1.5 Kgs, offering an elite gain-to-weight ratio for quick-deploy masts.
- Scalable Array Formation: Supports DUAL or QUAD stacked formations for ultra-high-gain requirements using custom phasing harnesses.
EW, SIGINT & Monitoring Compatibility
- Electronic Warfare (EW): Acts as a high-intensity directional jammer for 1.7–2.0 GHz data links. Its circular polarization ensures the jamming signal is not rejected by polarization-diversity filters.
- Signals Intelligence (SIGINT): The narrow 25-degree beamwidth facilitates accurate emitter triangulation and the interception of weak, long-range L-band telemetry.
- Persistent Monitoring: Serves as a high-fidelity electronic "tripwire" for situational awareness in high-reflection environments like urban canyons or maritime corridors.
Global & Environmental Compliances
- MIL-STD-810G Hardened: Designed to meet rigorous military protocols for Temperature, Humidity, Shock, and Vibration.
- RoHS & REACH: Constructed with lead-free, eco-friendly components compliant with EU chemical safety registrations.
- WEEE Directive: Supports sustainable 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 stable link in metallic or subterranean environments.
- Radome Feature Advantage: The high-strength ABS radome protects the copper radiator from sand abrasion and prevents ice accumulation from detuning the antenna.
- Precision Targeting: The 25-degree beamwidth allows for highly accurate signal projection and intercept.
Key Applications:
- Tactical Data Bridges: Establishing secure, high-capacity, long-range microwave links across hostile terrain.
- UAV Ground Control: High-reliability directional command and control for L-band tactical drones.
- L-Band Telemetry: Interception and monitoring of aerospace and missile telemetry.
- Satellite Telemetry: High-gain Ground-to-Space links for L-band satellite constellations.
Design Features: The AH-1800-16 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 extended range AH-1800-16 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.
