The HELI-22 is a high-performance, circular polarised, bi-directional fine/tunnel antenna for dual-band Wi-Fi. Ideal for M2M and IoT in mining, tunnels and construction, it offers 2.4 GHz and 5 GHz support, rugged IP65 construction, and enhanced MIMO compatibility, ensuring reliable connectivity in challenging underground environments.
The HELI-22 is designed for optimal decorrelation in MIMO deployments, offering superior performance through polarisation difference and spatial diversity. Its ability to propagate dual-band Wi-Fi signals around bends and through non-line-of-sight scenarios makes it particularly effective in industrial tunnels, providing reliable connectivity even in the presence of disruptive elements like trains and machinery.
Features:
- Dual-Band Wi-Fi Capability: Supports 2.4 GHz (9dBic) and 5 GHz (11dBic) bands, ensuring wide coverage.
- Circular Polarisation: Features Left-Hand Circular (LHC) and Right-Hand Circular (RHC) polarisation for enhanced signal propagation and stability.
- Bi-Directional Radiation: Uni-directional radiation in a tunnel, providing effective coverage in both directions.
- Rugged Construction: Designed to be ruggedized, with water and dust ingress protection (IP65), suitable for harsh mining conditions.
- Optimised for M2M and IoT: Ideal for telemetry and mine automation, enhancing MIMO performance in tunnels.
