AH-1726-13

Overview: AH-1726-13 Extended Range Helical Antenna

The AH-1726-13 is a professional-grade Extended Range Circular Polarized Helical Antenna designed for high-performance transmission and reception across the 1700–2600 MHz (1.7–2.6 GHz) spectrum. Delivering a stable 13 dBic gain, this directional aperture is engineered for long-range tactical data links, cellular band interception, and high-fidelity wireless bridges. By utilizing advanced helical winding and circular polarization (RHCP/LHCP), the AH-1726-13 provides superior signal "punch-through" and effectively eliminates multipath interference, outperforming traditional linear Yagi antennas in complex urban and subterranean environments.

Battlefield Durability: Built to survive the most punishing environmental extremes

The AH-1726-13 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-quality copper radiating elements secured within the radome to prevent geometry shifts and eliminate internal RF noise. Its optimized 40-degree beamwidth and stable 22 dB Front-to-Back ratio ensure that the 150W of RF power is concentrated toward the target—providing a generous acquisition window for mobile aerial assets while offering high isolation from rearward interference and background ground noise.

Detailed Technical Features

• Broadband L/S-Band Mastery: Seamlessly covers the entire 1700–2600 MHz window without field tuning.
• High-Gain Directional Output: Provides a consistent 13 dBic gain in a compact 450 mm profile.
• 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.
• High Front-to-Back Isolation: Offers a 22 dB ratio, ensuring signal purity and minimal rear-lobe emissions.
• 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 1.7–2.6 GHz data links. Its circular polarization ensures the jamming signal is not rejected by polarization-diversity filters.
• Signals Intelligence (SIGINT): The clean noise floor and directional gain allow operators to intercept weak, long-range telemetry and rogue tactical emitters with high fidelity.
• 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.
• Acquisition Window: The 40-degree beamwidth provides a wider "sweet spot," making it ideal for tracking fast-moving UAVs or mobile assets.

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/S-band tactical drones.
• Cellular Intercept: Specialized monitoring of wireless communications in the 1.7–2.6 GHz spectrum.
• Satellite Telemetry: High-gain Ground-to-Space links for L-band and S-band satellite constellations.
