Overview: AH-1013-15 High-Gain Circular Polarized Helical Antenna
The AH-1013-15 is a professional-grade Circular Polarized Helical Antenna precision-engineered for the 1050–1300 MHz frequency spectrum. Delivering a potent 15 dBic gain and a high 200-Watt power handling capacity, this directional aperture is a premier solution for L-band tactical data links, high-precision GNSS augmentation, and satellite telemetry. By utilizing advanced helical winding and circular polarization (RHCP/LHCP), the AH-1013-15 provides unmatched signal "punch-through" and effectively eliminates multipath interference, outperforming traditional linear antennas in complex urban theaters and subterranean military tunnels.
Battlefield Durability: Built to survive the most punishing environmental extremes
The AH-1013-15 is encased in a high-tech ruggedized radome made of high-strength fiberglass, 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, the antenna is fully MIL-STD-810G compliant. It maintains structural integrity in winds up to 200 Km/Hr, finished in tactical olive green for low observability in the field.
Operational Efficiency: Maximum power projection and signal integrity
Efficiency is maximized by securing high-purity enameled copper winding directly to the interior radome wall, preventing geometry shifts and eliminating internal RF inter-modulation. Its optimized 40-degree horizontal beamwidth and stable 18 dB Front-to-Back ratio ensure that up to 200W of RF power is concentrated exactly where it is needed—maximizing link distance for tactical data links while providing high isolation from rearward interference and background noise.
Detailed Technical Features
- Broadband L-Band Mastery: Precision-engineered to cover the 1050–1300 MHz window, supporting critical telemetry and tactical L-band frequencies.
- Elite 15 dBic High-Gain Output: The extended-stub helical design provides a powerful directional beam, offering superior long-range link stability compared to traditional linear arrays.
- Circular Polarization (CP) Superiority: Available in RHCP or LHCP to virtually eliminate Faraday rotation and effectively mitigate signal fading.
- High-Power Capacity: Industrial-grade construction facilitates sustained 200 Watts of continuous-duty RF transmission for Electronic Attack (EA).
- Focused Aperture Precision: Features a directional 40-degree horizontal / 35-degree vertical HPBW, ideal for precision target acquisition and satellite tracking.
- Low VSWR Architecture: Maintains a stable 1.5:1 VSWR across the operating band for maximum power transfer and transmitter protection.
- Advanced Inter-Modulation Protection: Radiating elements are secured to the radome walls to maintain precise electrical geometry under heavy vibration.
- Dual-Axis Tactical Steering: Supplied with a specialized mounting arrangement for 360° Azimuth and 90° Elevation tracking.
- Scalable Array Formation: Supports DUAL or QUAD stacked formations for ultra-high-gain requirements using custom power splitters.
EW, SIGINT & Monitoring Compatibility
- Electronic Warfare (EW): Acts as a high-intensity directional jammer for L-band communication links. Its circular polarization ensures the jamming signal bypasses linear anti-jam 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 military tunnels or maritime corridors.
Global & Environmental Compliances
- MIL-STD-810G Certified: Rigorously tested for High/Low Temperature, Humidity, Shock (Procedure IV), Vibration (Procedure I), Rain, Fungus, and Salt Fog.
- EU Compliance: Manufactured in strict adherence to RoHS (lead-free), REACH (chemical safety), and WEEE (recycling) directives.
- Ingress Protection: Radome is designed to withstand powerful water jets and dust ingress in coastal or desert theaters.
Key Advantages:
- Multipath Immunity: Inherently rejects reflected signals, providing a stable link in metallic or subterranean environments like military tunnels.
- Radome Feature Advantage: High-strength fiberglass radome offers near-zero signal attenuation and prevents ice accumulation from detuning the antenna in arctic theaters.
- Elite Front-to-Back Isolation: 18 dB ratio ensures signal purity and protects friendly systems behind the mast from high-power RF exposure.
Key Applications:
- Tactical L-Band Data Links: Establishing secure, high-capacity microwave links across hostile terrain.
- Tunnel Communications: Providing uninterrupted wireless links in subterranean military and industrial networks.
- Satellite Telemetry: High-gain Ground-to-Space links for L-band satellite constellations.
- UAV Ground Control: Directional command and control for L-band tactical drones.
Design Features: The AH-1013-15 uses extended stubs to provide the greater gain while maintaining the wider beam-width and designed to provide wideband directional transmission/reception of radio signals from 1050-1300 MHz bands including. This high-gain low-profile antennas use Circular Polarization Antenna Technology - which delivers better penetration through obstruction and interference. The AH-1013-15 helical antenna is highly suitable to provide the uninterrupted communications in the tunnels. 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-1013-15 Helical Antenna is supplied with a specially designed mounting arrangement to hold the antenna at back end by using stainless steel mounting brackets to withstand the higher wind rating. The AH-1013-15 helical antenna is supplied with a specially designed mounting arrangement for steering the antenna in both planes, 360 degrees in Azimuth and 90 degrees in Elevation for terrestrial and satellite link. Both LHCP and RHCP models are available. The part number for LHCP version is AH-1013-15-LHCP and AH-1013-15-RHCP is for RHCP version.
