AH-1417-16

Overview: AH-1417-16 High-Gain L-Band Helical Antenna

The AH-1417-16 is a professional-grade, Circular Polarized High-Gain Helical Antenna designed for the 1400–1700 MHz (1.4–1.7 GHz) frequency range. Delivering a potent 16 dBic gain and 150-Watt power handling capacity, this directional aperture is a premier solution for long-range tactical data links, UAV command systems, and satellite telemetry. By utilizing advanced helical winding and circular polarization (RHCP/LHCP), the AH-1417-16 provides superior signal "punch-through" and effectively eliminates multipath interference, outperforming traditional linear Yagi antennas in complex urban and high-reflection environments.

Battlefield Durability: Built to survive the most punishing environmental extremes

The AH-1417-16 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, the antenna is built to withstand winds up to 200 Km/Hr. Its resilient design is fully MIL-STD-810G compliant, ensuring mission-readiness in extreme thermal cycles, salt fog, and heavy rain.

Operational Efficiency: Maximum power projection and signal integrity

Efficiency is maximized by using high-purity enameled copper radiating elements secured directly to the interior radome walls, which prevents geometry shifts and eliminates internal RF inter-modulation. Its highly focused 30-degree beamwidth and stable 18 dB Front-to-Back ratio ensure that the 150W of RF power is concentrated exactly where it is needed—maximizing effective standoff distance for satellite tracking while providing high isolation from rearward interference and background ground noise.

Key Advantages: AH-1417-16 Tactical Superiority

• Total Multipath & Interference Rejection: Circular Polarization (CP) technology is inherently designed to reject reflected signals. By ignoring signal "fades" caused by bounces off metallic structures, water, or geographical obstructions, the AH-1417-16 ensures a stable, "locked-in" data link in high-reflection environments like military tunnels and urban canyons.
• Elite 16 dBic High-Gain Output: The extended-stub helical design concentrates RF energy into a powerful directional beam. This significantly increases the effective standoff distance for long-range tactical data links (TDL) and remote UAV command, outperforming significantly larger linear Yagi antennas.
• Superior Front-to-Back Isolation: With an 18 dB Front-to-Back ratio, this antenna ensures that radiated energy is projected forward toward the target. This provides critical protection for friendly systems and personnel located behind the antenna mast while minimizing the interception of background noise.
• Broadband L-Band Mastery: Covering the entire 1400–1700 MHz spectrum, a single AH-1417-16 serves various tactical L-band frequencies and satellite telemetry bands, reducing the need for multiple antenna swaps and simplifying logistics in the field.
• Radome Feature Advantage: The high-strength fiberglass and ABS radome offers near-zero signal attenuation. Its cylindrical profile prevents the "sail effect" in high winds (200 Km/Hr rating) and wicks away moisture to prevent ice accumulation from detuning the radiating elements.
• Zero Field Tuning: Fully factory-calibrated and environmentally sealed, this antenna is a "plug-and-play" asset. It requires no manual impedance matching or calibration, ensuring immediate mission-readiness upon deployment.

Key Applications: Mission-Critical Deployments

• UAV Ground Control Stations (GCS): Provides a high-reliability directional command, control, and telemetry link for L-band tactical drones. The 16 dBic gain ensures uninterrupted feeds even at maximum operational ranges.
• Satellite Telemetry & Tracking: Ideal for Ground-to-Space links for L-band satellite constellations. Its circular polarization ensures link integrity as satellites move across the horizon, eliminating signal loss due to Faraday rotation.
• Subterranean & Tunnel Communications: Engineered for uninterrupted wireless links in tunnels, mines, and underground bunkers where linear antennas typically fail due to extreme multipath interference.
• Electronic Warfare (EW) & Jamming: Serves as a high-intensity directional jammer for L-band data links. The 150W power capacity allows for the surgical saturation of enemy receivers at significant standoff distances.
• Signals Intelligence (SIGINT): The focused 30-degree beamwidth and clean noise floor allow operators to intercept, identify, and triangulate weak, long-range L-band telemetry and rogue tactical emitters.
• Point-to-Point Tactical Bridges: Establishing high-capacity, long-range secure data backhauls across hostile or uneven terrain where physical cable infrastructure is non-existent.
