The HELI-22 is a sophisticated Mini-HELI series antenna designed for efficient communication in mining and industrial tunnel environments. This circular polarised, bi-directional antenna caters to dual-band Wi-Fi frequencies, making it a versatile choice for M2M and IoT deployments in challenging underground settings.

Key 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.

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 mining tunnels, providing reliable connectivity even in the presence of disruptive elements like trains and machinery.
