Overview: AH-2400 High-Gain Flange-Mount Helical Antenna

The AH-2400 is a military-grade Circular Polarized Helical Antenna precision-engineered for the 2200–2600 MHz (2.2–2.6 GHz) spectrum. Delivering a robust 12 dBic gain in an ultra-lightweight 350-gram profile, this flange-mount aperture is optimized for UAV ground data terminals, tactical S-band links, and persistent communication in high-interference environments. By utilizing advanced helical winding and circular polarization (RHCP/LHCP), the AH-2400 provides superior signal penetration and multipath rejection, outperforming traditional linear antennas in complex subterranean tunnels and urban theaters.

Battlefield Durability: Built to survive the most punishing environmental extremes

The AH-2400 is encased in a high-tech ruggedized radome made of high-strength ABS, shielding 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. It maintains structural integrity in winds up to 200 Km/Hr and extreme thermal cycles, finished in tactical RAL 6014 or RAL 6003 or Customized color for low observability.

Operational Efficiency: Maximum power projection and signal integrity 

Efficiency is maximized by securing high-purity enameled copper winding directly to the radome wall, which prevents geometry shifts and eliminates internal RF inter-modulation. Its optimized 50-degree beamwidth and stable 17 dB Front-to-Back ratio ensure that the 200W of RF power is concentrated exactly where it is needed—maximizing link distance for UAV tracking and satellite communication while providing isolation from rearward interference and ground noise.

Detailed Technical Features

  • Broadband S-Band Mastery: Operates across the full 2200–2600 MHz window, supporting tactical data links and UAV command frequencies.
  • High-Gain Directional Output: Provides a consistent 12 dBic gain, outperforming significantly larger linear Yagi arrays.
  • Circular Polarization (CP) Mastery: Available in RHCP or LHCP to virtually eliminate Faraday rotation and mitigate signal fading.
  • High Power Capacity: Industrial-grade construction facilitates sustained 200 Watts of continuous-duty RF transmission.
  • Precision Flange Mounting: Features a 75mm x 75mm flange plate with a 6mm thickness, designed for secure integration with pan-tilt units or bulkheads.
  • Wide Sector Acquisition: Features a 50-degree HPBW (Half Power Beamwidth), facilitating easier tracking of mobile aerial assets and satellites.
  • Advanced Inter-Modulation Protection: High-strength copper elements are secured to the radome wall to maintain precise electrical geometry under vibration.
  • Tactical SWaP Profile: Extremely lightweight at ~350 grams with a compact 310 mm length, ideal for weight-sensitive mobile deployments.

EW, SIGINT & Monitoring Compatibility

  • Electronic Warfare (EW): Acts as a high-intensity directional jammer for 2.4 GHz digital data links and FPV triggers. Its circular polarization ensures the jamming signal bypasses linear anti-jam filters used in tactical receivers.
  • Signals Intelligence (SIGINT): The clean noise floor and directional gain allow operators to intercept weak, long-range S-band telemetry and rogue tactical emitters with high fidelity.
  • Persistent Monitoring: Serves as a high-gain 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.
  • IP66 Rating: The radome and flange interface are designed to withstand powerful water jets and dust ingress in coastal or tropical climates.
  • EU Compliance: Manufactured in strict adherence to RoHS (lead-free), REACH (chemical safety), and WEEE (recycling) directives.

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 offers near-zero signal attenuation and prevents ice accumulation from detuning the antenna in arctic theaters.
  • Integrated Steering Capability: Designed for easy mounting on specialized tracking arrangements for 360° Azimuth and 90° Elevation control.

Key Applications:

  • UAV Ground Data Terminals: High-reliability directional command and control for tactical drones.
  • Tunnel Communications: Providing uninterrupted wireless links in subterranean military and industrial networks.
  • Point-to-Point Tactical Bridges: Establishing secure, high-capacity data links across hostile terrain.
  • Satellite Telemetry: High-gain Ground-to-Space links for S-band satellite constellations.

 

Design Features: The AH-2400 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-2400 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.

Constructions: The AH-2400, like all our AH series helical antennas, utilizes circular polarization to minimize the effects of multipath interference. Both Right Hand Circular Polarized (RHCP) and Left Hand Circular Polarized (LHCP) helical antenna models are available. The AH-2400 Helical Antenna is light weight, broadband and rugged helical antennas, supplied with ABS radome to protect the antenna from environment. Cylindrical enclosure is used for low wind loading and for minimal effect of ice formation on the helical antenna operation as well as providing an aesthetically pleasing appearance.

For higher gain requirement, the Helical antenna can be supplied in DUAL stacked or QUAD stacked arrays with suitable power splitter/combiner cable harness.
