AH-2400-16

Overview: AH-2400-16 High-Gain Extended Range Helical Antenna

The AH-2400-16 is a professional-grade Extended Range Circular Polarized Helical Antenna precision-engineered for the 2200–2600 MHz (2.2–2.6 GHz) spectrum, including the full ISM band. Delivering a potent 16 dBic gain, this directional aperture is a premier solution for long-range tactical data links, UAV command systems, and high-performance wireless bridges. By utilizing advanced helical winding and circular polarization (RHCP/LHCP), the AH-2400-16 provides unmatched signal "punch-through" and multipath rejection, outperforming traditional linear Yagi antennas in complex subterranean environments and high-interference urban theaters.

Battlefield Durability: Built to survive the most punishing environmental extremes

The AH-2400-16 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 -40°C to +70°C.

Operational Efficiency: Maximum power projection and signal integrity achieved through advanced RF engineering

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 highly focused 25-degree beamwidth and exceptional 32 dB Front-to-Back ratio ensure that the 150W of RF power is concentrated exactly where it is needed, maximizing effective standoff distance while providing extreme isolation from rearward interference and ground noise.

Global Compliances & MIL-STD Hardening

The AH-2400-16 is rigorously tested to MIL-STD-810G protocols, ensuring 24/7 survivability in the most hostile tactical environments:

EU Environmental & Safety Compliances

To meet international regulatory and environmental safety standards for global deployment, the AH-2400-16 adheres to the following:

• RoHS Compliant: Restricted use of hazardous substances (Lead, Mercury, Cadmium, etc.) in all electronic components and solder joints.
• REACH Compliant: Ensures all chemical substances used in the fiberglass radome and copper coatings are registered and safe for human health and the environment.
• WEEE Directive: Designed for high-end lifecycle management with recyclable aluminum and copper materials, facilitating sustainable disposal.
• CE Mark: Fully compliant with EU safety, health, and environmental protection requirements.

Key Advantages: AH-2400-16 Tactical Superiority

• Unmatched Multipath Rejection: Circular Polarization (CP) technology is inherently designed to reject reflected signals. This ensures an ultra-stable, "flicker-free" data link in high-reflection environments like military tunnels, metallic ship decks, and dense urban canyons where linear antennas suffer from destructive interference.
• Elite 16 dBic High-Gain Output: The extended-stub design concentrates RF energy into a powerful directional beam, significantly increasing the effective standoff distance for long-range tactical data links (TDL) and remote UAV command.
• Superior Front-to-Back Isolation: With a class-leading 32 dB Front-to-Back ratio, this antenna ensures that nearly all radiated energy is projected forward. This provides exceptional protection for friendly systems and personnel located behind the antenna mast while minimizing the interception of background noise.
• Wideband 2.4 GHz Mastery: Covering the entire 2200–2600 MHz spectrum, a single AH-2400-16 serves both tactical S-band frequencies and standard ISM bands, reducing the need for multiple antenna swaps in the field.
• Zero Field Tuning: Fully factory-tuned and environmentally sealed, this antenna is a "plug-and-play" asset that requires no manual calibration or impedance matching, ensuring mission-readiness the moment it is deployed.

Radome Feature Advantages

• Aerodynamic Cylindrical Profile: The 900 mm cylindrical design minimizes wind drag (180 Km/Hr rating) and prevents the "sail effect," ensuring the antenna remains precisely bore-sighted on the target during high-velocity wind events.
• High-Tech RF Transparency: Engineered from specialized high-strength fiberglass and ABS, the radome offers near-zero signal attenuation, ensuring that the full 16 dBic gain is delivered without internal losses.
• Ice and Snow Shedding: The smooth, moisture-wicking exterior prevents the accumulation of ice and snow, which typically detunes or damages exposed radiating elements in arctic or high-altitude theaters.
• Corrosion-Proof Shielding: Finished with an olive green MIL-spec coating, the radome is immune to the corrosive effects of salt fog, acid rain, and intense UV radiation, making it ideal for permanent coastal or naval installations.
• Radiator Geometry Protection: The radome serves as a rigid structural skeleton, securing the heavy-duty copper winding in a fixed geometry. This prevents RF inter-modulation and phase shifts that can be caused by mechanical vibration or wind-induced swaying.

Key Applications

• UAV Ground Control Stations (GCS): High-reliability directional command, control, and high-definition video downlink for S-band tactical drones.
• Subterranean Military Networks: Providing uninterrupted wireless links in tunnels, mines, and underground bunkers where multipath interference is extreme.
• Electronic Warfare (EW) & Jamming: High-intensity directional saturation of 2.4 GHz digital data links and FPV triggers.
• Point-to-Point Tactical Bridges: Establishing secure, long-range microwave data bridges across hostile or uneven terrain where cable infrastructure is impossible.
• Satellite Telemetry & Tracking: High-gain Ground-to-Space links for S-band satellite constellations and LEO satellite tracking.
• Maritime Data Links: Secure ship-to-ship and ship-to-shore communications, utilizing circular polarization to overcome signal fading over water.
