AH-1117-16

Overview: AH-1117-16 High-Gain All-GPS & Drone Jammer Helical Antenna

The AH-1117-16 is a military-grade Circular Polarized High-Gain Helical Antenna precision-engineered for the 1100–1700 MHz spectrum. Delivering a potent 16 dBic gain and a high 250-Watt power handling capacity, this directional aperture is a premier solution for strategic GNSS denial (GPS L1, L2, L5, L6), drone defense systems, and tactical L-band data links. By utilizing advanced helical winding and circular polarization (RHCP/LHCP), the AH-1117-16 provides unmatched signal "punch-through" and effectively eliminates multipath interference, outperforming traditional linear antennas in complex subterranean tunnels and high-interference urban theaters.

Battlefield Durability: Hardened construction materials built to survive the most punishing environmental extremes. 

The AH-1117-16 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 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 olive green for low observability.

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 28-degree beamwidth and exceptional 30 dB Front-to-Back ratio ensure that the 250W of RF power is concentrated exactly where it is needed—maximizing effective standoff distance for drone denial and satellite tracking while providing extreme isolation from rearward interference and background ground noise.

Detailed Technical Features: AH-1117-16 High-Gain Helical Antenna

• Universal GNSS & L-Band Optimization: Precision-engineered to cover the massive 1100–1700 MHz frequency window, providing a "single-antenna" solution for GPS L1, L2, L5, L6, Galileo, GLONASS, and tactical L-band data links without field tuning.

• Extreme Front-to-Back Isolation: Achieves an exceptional 30 dB (+/-2 dB) ratio, ensuring maximum forward energy projection while "darkening" the rear sector to protect friendly systems and minimize background noise intercept.
• Advanced Inter-Modulation Protection: High-purity enameled copper radiating elements are secured directly to the interior radome walls to maintain precise electrical geometry under extreme vibration and high-velocity wind loads.
• Dual-Axis Tactical Steering: Supplied with a specialized heavy-duty mount allowing for 360° Azimuth and 0–90° Elevation tracking for both terrestrial assets and orbital satellites.

Key Advantages: AH-1117-16 Tactical Superiority

• Universal GNSS Denial & Protection: By covering the entire 1100–1700 MHz spectrum, the AH-1117-16 serves as a "master antenna" for GNSS operations. It provides high-gain stability across GPS (L1, L2, L5, L6), GLONASS, Galileo, and BeiDou bands, allowing operators to secure or deny all global navigation frequencies with a single aperture.
• Elite 16 dBic Gain-to-Size Ratio: The extended-stub helical design provides a potent 16 dBic gain, concentrating RF energy into a tight, high-intensity beam. This enables surgical long-range "punch-through" capability for data links or jamming signals that significantly out-distances larger, more fragile linear antennas.
• Unmatched Front-to-Back Isolation: A class-leading 30 dB Front-to-Back ratio ensures that radiated energy is exclusively projected forward toward the target. This "darkens" the area behind the antenna mast, protecting friendly systems and personnel from high-power RF exposure while minimizing the interception of background noise.
• Total Multipath & Circular Stability: Circular Polarization (CP) technology inherently rejects multipath interference. By ignoring signal reflections that undergo a polarization flip, the AH-1117-16 ensures a stable link in complex metallic or subterranean environments like military tunnels, aircraft hangers, and urban centers.
• Advanced Radome Engineering: The high-strength cylindrical radome offers near-zero signal attenuation. Its aerodynamic profile prevents the "sail effect" in high winds (200 Km/Hr rating) and features a moisture-wicking exterior that prevents ice accumulation from detuning the antenna in arctic or high-altitude theaters.
• Industrial-Grade Power Density: Engineered to handle a continuous 250 Watts of RF power, this antenna is designed for persistent, high-intensity operation. The internal copper radiators are secured directly to the radome walls to prevent geometry shifts or inter-modulation even under heavy thermal or vibration loads.

Key Applications: Mission-Critical Deployments

• Counter-UAV (C-UAV) & Drone Defense: Serves as the primary directional aperture for high-power drone defense systems. It is optimized for the surgical jamming of GPS-dependent navigation and L-band control links (C2), effectively grounding rogue aerial assets at significant standoff distances.
• Strategic GNSS Denial (GPS Jamming): Ideal for Electronic Attack (EA) missions requiring the denial of PNT (Positioning, Navigation, and Timing) across a theater. The 16 dBic gain allows for the saturation of enemy GPS receivers across all primary bands (L1 through L6).
• UAV Ground Control Stations (GCS): Provides a high-reliability directional command, control, and telemetry link for tactical drones. The circular polarization ensures link integrity as the drone maneuvers, eliminating signal "cross-polarization" fading.
• Satellite Telemetry & Tracking: High-gain Ground-to-Space links for L-band satellite constellations. Its precision steering and narrow beamwidth allow for accurate tracking of satellites from the horizon to the zenith.
• Signals Intelligence (SIGINT): The clean noise floor and focused 28-degree beamwidth allow SIGINT operators to intercept, identify, and triangulate weak, long-range L-band telemetry and rogue emitters with high angular precision.
• Subterranean Military Networks: Providing uninterrupted wireless links in tunnels, mines, and underground bunkers where traditional linear antennas fail due to destructive multipath interference.

EW, SIGINT & Monitoring Compatibility

• Electronic Warfare (EW) & Drone Denial: Acts as a high-intensity directional jammer for the entire GPS/GNSS spectrum and C2 drone links. Its circular polarization ensures the jamming signal is not rejected by polarization-diversity filters used in tactical receivers.
• Signals Intelligence (SIGINT): The narrow 28-degree beamwidth and clean noise floor allow operators to intercept weak, long-range GPS 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.
