A-HELI-0042-V2-01
Dual-Band Bi-Directional Wi-Fi Antenna for Mining and Tunnel Applications

The HELI-42 is part of the Mini-HELI antenna series, offering medium to high gain performance in a compact design. This dual-band 2.4 GHz and 5 GHz Wi-Fi antenna provides bi-directional coverage, making it ideal for seamless connectivity in mining tunnels and industrial environments. The HELI-42 enhances IoT, telemetry, and automation applications, ensuring reliable communication even in challenging underground conditions.

Dual-Band Wi-Fi Coverage: Supports both 2.4 GHz and 5 GHz frequency bands for high-performance wireless communication.
Bi-Directional Radiation Pattern: Provides extended coverage along tunnels, enhancing network stability and connectivity.
Optimized for High-Density MIMO Deployments: Compatible with 4x4 and 8x8 MIMO configurations using the BRKT-46 mount.
Left-Hand & Right-Hand Circular Polarization: Improves decorrelation, reducing interference and enhancing MIMO performance.
Non-Line-of-Sight (NLOS) Propagation: Circular polarization allows signals to navigate around tunnel bends and obstacles.
Rugged Industrial Design: Engineered for underground applications, ensuring durability and resistance to environmental disruptions.

The HELI-42 is a powerful Wi-Fi antenna solution for mining and industrial environments, delivering robust and stable connectivity in complex tunnel networks.

Ideal Applications

  • Supplementing fibre/leaky feeder cable “Hotspots” to areas to enhance mobility or extend networks to inaccessible areas
  • Underground telemetry and automation
  • Creating of complete underground in tunnel wide data networks and internet/ LTE connectivity
  • Seamless connection to personnel using cellular phones, smart devices and tablets
