DH2413-5814-SMAF Helical Antenna
The DH2413-5814-SMAF Helical Antenna is a high-performance, dual-band antenna designed for mission-critical wireless systems operating across the 2.4 GHz and 5.8 GHz ISM frequency bands.
Description
The DH2413-5814-SMAF Helical Antenna is a high-performance, dual-band antenna designed for mission-critical wireless systems operating across the 2.4 GHz and 5.8 GHz ISM frequency bands. Featuring a circularly polarized helical design, it provides enhanced multipath mitigation, consistent radiation patterns, and improved link stability in reflective or high-interference environments.
Optimized for use in C‑UAS platforms, industrial automation, IIoT networks, M2M communication, and defense applications, the DH2413-5814-SMAF offers low axial ratio, high gain, and exceptional RF robustness. The circular polarization enables superior signal penetration through metal- and moisture-rich environments such as tunnels, mines, and warehouses, ensuring dependable connectivity where linear antennas underperform.
