Description
The H5818-NF is a high-gain, right-hand circularly polarized (RHCP) helical antenna, designed for wideband performance across the 4.9 to 6.0 GHz frequency range. With an 18 dBic gain, this antenna delivers extended range, enhanced signal strength, and superior interference mitigation, making it ideal for counter-UAS (C-UAS) operations, military and defense communications, underground mining, and industrial automation applications.
Its circular polarization improves signal reliability by minimizing multipath interference from metallic surfaces, tunnels, and other reflective environments, ensuring consistent, high-efficiency transmission in complex RF conditions. Optimized for wireless security, IIoT, machine-to-machine (M2M) communication, and long-range surveillance, the H5818-NF supports secure and stable connectivity in mission-critical applications.
Built for rugged durability, this antenna withstands harsh environmental conditions, making it a trusted solution for defense, industrial, and high-performance wireless networks requiring uninterrupted communication.
