| AH-5759 | High Gain Circular Polarized Helical Antenna | 5700-5900MHz | 16 dBic |  |  |  |
The AH-5759 is an ultra-high gain Circular Polarized Helical Antenna precision-engineered for the 5700–5900 MHz (5.8 GHz) ISM and C-band spectrum. Delivering a potent 16+ dBic gain in a remarkably compact 255 mm profile, this directional aperture is a premier solution for high-density 5.8 GHz tactical data links, UAV command systems, and long-range point-to-point bridges. By utilizing advanced helical winding and circular polarization (RHCP/LHCP), the AH-5759 provides unmatched signal "punch-through" in high-interference zones, outperforming traditional linear antennas in complex subterranean and urban theaters.
Battlefield Durability: Built to survive the most punishing environmental extremes
The AH-5759 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 maximizing power throughput. Its highly focused 25-degree beamwidth and high 18 dB Front-to-Back ratio ensure that the 150W of RF power is concentrated exactly where it is needed, significantly extending the effective standoff distance for both communication and Electronic Attack missions.

Strategic EW, SIGINT & Monitoring Compatibility: AH-5759
The AH-5759 is an ultra-high gain directional asset designed for full-spectrum dominance in the 5.8 GHz (5700–5900 MHz) range. By utilizing Circular Polarization, it serves as a unified aperture for Electronic Warfare (EW), Signals Intelligence (SIGINT), and persistent Spectrum Monitoring, specifically excelling in high-multipath environments like urban canyons and tunnels.
1. Electronic Warfare (EW) & Electronic Attack (EA)
In Electronic Attack missions, the AH-5759 acts as a High-Intensity Polarization-Matched Jammer. Its helical architecture is engineered to bypass the defenses of modern tactical receivers.
- Penetrating Polarization Diversity: Most modern anti-jam receivers use linear polarization diversity to filter out interference. Because the AH-5759 uses Circular Polarization (RHCP/LHCP), the jamming energy is effectively "locked" to the target signal regardless of the victim antenna's orientation, preventing the standard 3 dB polarization loss.
- 150W Directional Suppression: With a 16+ dBic gain and a highly focused 25-degree beamwidth, this antenna can project a concentrated "denial beam" to saturate 5.8 GHz FPV drone links, digital data backhauls, and ISM-band control links at significant standoff distances.
- Multipath Immunity: In complex environments like tunnels or metallic corridors, reflected linear signals often flip polarization and cancel each other out. The AH-5759 maintains link integrity by utilizing the inherent "handedness" of circular waves to reject reflected interference.
2. Signals Intelligence (SIGINT) & Electronic Support (ES)
For SIGINT operators, the AH-5759 is an elite Long-Range Intercept Tool. Its high gain and clean noise floor are essential for modern digital intercept receivers.
- Faint Signal Recovery: The 16+ dBic gain allows operators to recover weak, distant 5.8 GHz telemetry and tactical communications that would be lost in the noise floor of standard omni-directional or low-gain antennas.
- Precision Direction Finding (DF): The narrow 25° horizontal and vertical beamwidth provides high angular resolution, allowing SIGINT teams to accurately triangulate the location of rogue emitters.
- High Front-to-Back Isolation: An 18 dB ratio ensures that the antenna focuses exclusively on the target sector, minimizing background noise intercept and interference from friendly systems located behind the aperture.

Design Features: The AH-5759 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-5759 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.
