| AH-2733 | High Gain Circular Polarized Helical Antenna | 2700-3300MHz | 15 dBic |  |  |  |
The AH-2733 is a professional-grade, Extended Range Circular Polarized High-Gain Helical Antenna engineered for the 2700–3300 MHz (2.7–3.3 GHz) frequency band. Delivering a potent 15 dBic gain, this directional aperture is a premier solution for S-band tactical data links, telemetry, and high-performance communication in challenging environments. By utilizing advanced helical winding and circular polarization (RHCP/LHCP), the AH-2733 provides superior signal penetration and multipath rejection, outperforming traditional linear antennas in complex subterranean and urban theaters.
Battlefield Durability: Built to survive the most punishing environmental extremes
The AH-2733 is encased in a high-tech ruggedized radome made of high-strength fiberglass and ABS, shielding the precision copper radiating elements from physical impact, ice loading, and corrosive atmospheres. Featuring a 6063T6 aluminum alloy reflector and marine-grade stainless steel hardware, this antenna is fully compliant with MIL-STD-810G protocols, maintaining structural integrity in winds up to 200 Km/Hr and extreme thermal cycles from -30°C to +70°C.
Operational Efficiency: Maximum power projection and signal integrity
Efficiency is maximized by securing high-purity enameled copper winding directly to the radome wall, minimizing internal RF inter-modulation and maximizing power throughput. Its highly focused 30-degree beamwidth and exceptional 22 dB Front-to-Back ratio ensure that the 150W of RF power is concentrated exactly where it is needed, significantly extending the effective standoff distance while providing high isolation from rearward interference.
Technical Features
- High-Gain S-Band Performance: Delivers a typical gain of 15 dBic for superior link stability over long distances.
- Broadband Coverage: Operates across the full 2700–3300 MHz window without field adjustments.
- Circular Polarization: Available in RHCP or LHCP to eliminate Faraday rotation and effectively mitigate multipath fading.
- Tactical Steering Suite: Supplied with a specialized mounting arrangement for 360° Azimuth and 90° Elevation tracking.
- Flexible Mounting: Supports both pole/mast mounting and flange mounting for direct integration with pan-tilt mechanisms.
- Low Wind Loading: Cylindrical radome design reduces drag and prevents ice accumulation in arctic or high-altitude theaters.
Strategic EW, SIGINT & Monitoring Compatibility
- Electronic Warfare (EW): Acts as a high-intensity directional jammer for S-band 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 electronic "tripwire" for situational awareness in high-reflection environments like military tunnels or mines.
Global & Environmental Compliances
- MIL-STD-810G Hardening: Fully certified for High/Low Temp, Humidity, Shock, Vibration, Rain, Fungus, and Salt Fog.
- RoHS & REACH: Constructed with eco-friendly, lead-free components compliant with EU chemical safety registrations.
- WEEE & CE: Adheres to the Waste Electrical and Electronic Equipment directive and all European Union safety and health requirements.
Key Advantages
- Multipath Rejection: Inherently rejects reflected signals, ensuring ultra-clean data links in urban canyons or metallic corridors.
- Compact SWaP Profile: Weighs only less than1 Kg with a length of 300 mm, offering an elite gain-to-weight ratio for tactical masts.
- High Power Density: Capable of sustained 150 Watts of continuous-duty RF transmission.
- Zero Field Tuning: Fully factory-tuned architecture for immediate "plug-and-play" tactical deployment.
Key Applications
- UAV Ground Control Stations: High-reliability directional command and control for S-band tactical drones.
- Tunnel Communications: Providing reliable wireless links in subterranean military and industrial networks.
- Point-to-Point Tactical Bridges: Establishing high-capacity, long-range secure data links across hostile terrain.
- Satellite Telemetry: High-gain Ground-to-Space links for S-band satellite constellations.
Design Features:The AH-2733 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-2733 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.
