| AH-4060-12 | High Gain Circular Polarized Helical Antenna | 4000-6000MHz | 12 dBi |  |  |  |
The AH-4060-12 is a professional-grade High-Gain Circular Polarized Helical Antenna engineered for the 4000–6000 MHz (4–6 GHz) spectrum. Delivering a robust 12 dBic gain across a massive 2000 MHz bandwidth, this directional aperture is a premier solution for C-band tactical data links, UAV command systems, and satellite telemetry. By utilizing advanced helical winding technology and circular polarization (RHCP/LHCP), the AH-4060-12 provides superior signal penetration and link stability, outperforming traditional linear antennas in complex, high-multipath environments like tunnels and urban canyons.
Battlefield Durability: Built to survive the most punishing environmental extremes
The AH-4060-12 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 6061T6 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 ensuring precise phase alignment. Its focused 40-degree beamwidth and exceptional 20 dB Front-to-Back ratio ensure that the 50W of RF power is concentrated exactly where it is needed, maximizing link distance while preventing interference with friendly systems located behind the aperture.
Technical Features
- Ultra-Wideband C-Band Performance: Seamlessly covers the entire 4000–6000 MHz window with a massive 2 GHz bandwidth.
- High-Gain Directional Output: Delivers a typical gain of 12 dBic for superior mid-range link stability.
- Circular Polarization Technology: Available in RHCP or LHCP to eliminate Faraday rotation and effectively mitigate multipath fading.
- Precision Steering: Supplied with a specialized mounting arrangement for 360° Azimuth and 90° Elevation tracking for terrestrial and satellite links.

Strategic EW, SIGINT & Monitoring Compatibility
- Electronic Warfare (EW): Acts as a high-intensity directional jammer for C-band data links, utilizing circular polarization to bypass linear anti-jam filters.
- Signals Intelligence (SIGINT): The clean noise floor and 12 dBic gain allow for the interception of weak, long-range microwave telemetry and tactical signals.
- Persistent Monitoring: Provides high angular resolution for situational awareness and the characterization of rogue emitters in the 4-6 GHz window.
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 hazardous substance and 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 Immunity: Inherently rejects reflected signals, ensuring ultra-clean data links in urban canyons or metallic corridors.
- Superior Form Factor: Smaller and more rugged than conventional C-band Yagi or parabolic dish antennas.
- Zero Field Tuning: Fully factory-tuned architecture for immediate "plug-and-play" tactical deployment.
- Low Wind Loading: Cylindrical design prevents "sail" effects and ice accumulation on the mast.
Key Applications
- UAV Ground Control Stations: High-reliability directional command and control for C-band tactical drones.
- Satellite Telemetry: High-gain Ground-to-Space links for 4-6 GHz satellite constellations.
- Tunnel Communications: Providing uninterrupted wireless links in high-reflection subterranean military and industrial networks.
- Microwave Backhaul: Establishing secure, long-range point-to-point data bridges across hostile terrain.
Design Features: The AH-4060-12 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. The AH-4060-12 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-4060-12 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-4060-12 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-4060-12-LHCP and AH-4060-12-RHCP is for RHCP version.
