Uni-Directional Ultra-Wideband Antenna for IoT and Mining Tunnels

The HELI-31 is part of Poynting’s Mini-HELI series, designed to provide reliable ultra-wideband connectivity in mining tunnels where IoT and M2M communication is essential. Despite its compact size compared to larger models, the HELI-31 delivers medium to high gain performance, making it ideal for coverage into stopes and throughout tunnel environments. This uni-directional antenna radiates signals in one direction, ensuring optimal tunnel-wide connectivity for telemetry, mine automation, and industrial IoT deployments.

Ultra-Wideband Frequency Coverage: Operates from 1710 MHz to 7200 MHz, supporting a wide range of applications.
Optimized for Tunnel Communications: Ensures reliable connectivity for mining, industrial, and IoT environments.
Uni-Directional Design: Provides focused signal coverage in a single direction, making it ideal for controlled network expansion.
Non-Line of Sight (NLOS) Propagation: Wi-Fi and IoT 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-31 is an ideal solution for mining tunnels, delivering reliable, uni-directional ultra-wideband connectivity to support industrial automation, IoT, and M2M applications in demanding underground environments.
