| AH-3500 | High Gain Circular Polarized Helical Antenna | 3300-3800MHz | 15 dBic |  |  |  |
The AH-3500 is a professional-grade, Extended Range Circular Polarized High-Gain Helical Antenna precision-engineered for the 3300–3800 MHz (3.3–3.8 GHz) spectrum. Delivering a potent 15 dBic gain in an ultra-compact 400-gram form factor, this directional aperture is a premier solution for 5G sub-6 GHz testing, tactical data links, and high-performance communication in high-interference environments. By utilizing advanced helical winding and circular polarization (RHCP/LHCP), the AH-3500 provides unmatched signal "punch-through" 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-3500 is encased in a high-tech ruggedized fiberglass radome that shields 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 30 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 extreme isolation from rearward interference.
Technical Features
- Extended Range Performance: Delivers a potent 15 dBic gain for superior link stability over long distances.
- Wideband 500 MHz Coverage: Operates across the full 3300–3800 MHz window without field adjustments.
- Circular Polarization: Available in RHCP or LHCP to eliminate Faraday rotation and effectively mitigate multipath fading.
- Steering Versatility: Supplied with a flange mount; optional tracking mount allows for 360° Azimuth and 90° Elevation steering.
- Extreme SWaP Efficiency: Weighs only 400 grams, making it ideal for weight-sensitive mobile masts and man-pack kits.
- Low Wind Loading: Cylindrical radome design reduces drag and prevents ice accumulation in arctic or high-altitude theaters.
MIL-STD-810G Compliances
The AH-3500 is rigorously tested to MIL-STD-810G protocols, ensuring 24/7 survivability in the most hostile tactical environments:

| Wind Rating | Aerodynamic | Structural integrity maintained in high-velocity winds up to 200 Km/Hr. |
Strategic EW, SIGINT & Monitoring Compatibility
- Electronic Warfare (EW): Acts as a high-intensity directional jammer for 3.5 GHz 5G and tactical links, utilizing circular polarization to bypass linear anti-jam filters.
- Signals Intelligence (SIGINT): The narrow 30-degree beamwidth and high Front-to-Back ratio facilitate 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 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.
- High Front-to-Back Isolation: 30 dB ratio ensures maximum signal purity and prevents interference from friendly systems.
- 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
- 5G Sub-6 GHz Testing: High-gain directional link for network verification and optimization.
- Tunnel Communications: Providing reliable wireless links in subterranean military and industrial networks.
- Point-to-Point Tactical Bridges: Establishing secure, high-capacity data links across hostile terrain.
- UAV Ground Control: Directional command and control links for tactical drones in the 3.5 GHz window.
Design Features: The AH-3500 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-3500 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.
