The Poynting HELI-21 is a rugged, uni-directional tunnel antenna designed for high-performance wireless communication in mining and tunnel environments. Operating across the 2.4 GHz and 5 GHz Wi-Fi bands, this antenna is ideal for delivering stable connectivity in non-line-of-sight scenarios, even around tunnel bends and in the presence of signal-disrupting objects.

Product Features:

• The Poynting HELI-21 antenna operates in both the 2.4 GHz and 5 GHz Wi-Fi bands, supporting dual-band wireless communication.
• It features circular polarisation, available in both left-hand (LHC) and right-hand (RHC) variants, enhancing signal propagation and reducing interference.
• This antenna is uni-directional, radiating in a single direction, making it ideal for focused coverage in tunnels and corridors.
• It is designed to maintain strong signal performance in environments with obstructions such as trains and drilling machinery.
• The ruggedised enclosure is rated IP65, offering protection against dust and water ingress for reliable operation in harsh conditions.
• It is purpose-built for industrial use, ensuring durability and consistent performance in demanding tunnel environments.
• The antenna includes the BRKT-45 mounting bracket for secure and easy installation.

Application Areas:

• The antenna is ideal for mining tunnels requiring directional Wi-Fi coverage for telemetry and automation.
• It is suitable for tunnel-based IoT and M2M deployments where stable and focused signal coverage is essential.
• This device is effective in underground transport systems and industrial corridors.
• It is also applicable in enclosed environments with high interference where directional signal control is needed.
