The HELI-13 is part of POYNTING’s Mini-HELI series, designed to provide reliable dual-band 2.4 GHz and 5 GHz 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-13 delivers medium to high gain performance, making it ideal for coverage into stopes and throughout tunnel environments. This bi-directional antenna radiates signals in both directions, ensuring optimal tunnel-wide Wi-Fi coverage for telemetry, mine automation, and IoT deployments.

Optimized for Tunnel Communications: Supports dual-band 2.4 GHz and 5 GHz Wi-Fi, ensuring reliable coverage for mining and industrial tunnels.
Bi-Directional Design: Provides signal coverage in both directions, making it ideal for long tunnels and extended connectivity.
MIMO-Optimized Deployment: Available in Left-Hand Circular (LHC) and Right-Hand Circular (RHC) polarisation, enhancing MIMO performance when used with the BRKT-45 mount.
Non-Line of Sight (NLOS) Propagation: Wi-Fi signals can propagate around tunnel bends, overcoming obstacles such as 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, ensuring long-term reliability in mining environments.

The HELI-13 is an ideal solution for mining tunnels, delivering reliable, dual-band Wi-Fi connectivity to support industrial automation, IoT, and M2M applications in demanding underground environments.
