Poynting HELI-19-R-IS Bi-Directional Wi-Fi Antenna
The HELI-19-R-IS is a compact, dual-band Wi-Fi antenna for IoT and M2M applications in mining tunnels. Its bi-directional design ensures reliable coverage along tunnels, supporting telemetry, automation, and underground connectivity in harsh environments.
- Dual-band Wi-Fi: 2.4 GHz and 5 GHz for reliable tunnel coverage
- Bi-directional radiation pattern for extended connectivity in both directions
- MIMO-optimized deployment with Right-Hand Circular polarisation
- Non-Line of Sight (NLOS) propagation around tunnel bends and obstacles
- Enhanced RF reliability in metallic and harsh underground environments
- Compact, durable, and intrinsically safe (IS) construction
- Ideal for underground telemetry, IoT, automation, and personnel connectivity
