A-HELI-0011-V3-01

Compact Uni-Directional Wi-Fi Antenna for IoT and Mining Tunnels

The HELI-11 is part of Poynting’s Mini-HELI series, designed to provide reliable Wi-Fi connectivity in mining tunnels where IoT and M2M communication is essential. Despite its compact size compared to larger models like the HELI-3, HELI-4, and HELI-8, the HELI-11 delivers medium to high gain performance, making it ideal for coverage into stopes and throughout tunnel environments. This 2.4 GHz Wi-Fi antenna radiates in one direction (uni-directional), ensuring optimal signal coverage for telemetry, mine automation, and IoT deployments in mining and industrial tunnels.

Optimized for Tunnel Communications: Designed to enhance Wi-Fi coverage in mining and underground tunnels, supporting telemetry and mine automation.
Uni-Directional Design: Focuses 2.4 GHz Wi-Fi signals in one direction, ensuring efficient coverage in confined tunnel spaces.
MIMO-Optimized Deployment: Available in Left-Hand Circular (LHC) and Right-Hand Circular (RHC) polarisation, improving MIMO performance when deployed with the BRKT-45 mount.
Non-Line of Sight (NLOS) Propagation: Wi-Fi signals can propagate around tunnel bends, overcoming obstacles like mining equipment and trains.
Enhanced RF Reliability: Reduces signal degradation caused by metallic surfaces, machinery, and tunnel curvature.
Compact and Durable Construction: Engineered for harsh underground conditions, offering long-term reliability in mining environments.

The HELI-11 is an ideal solution for mining tunnels, delivering robust and reliable Wi-Fi connectivity to support industrial automation, IoT, and M2M applications in demanding underground environments.
