A-HELI-0041-V2-01

Dual-Band Uni-Directional Wi-Fi Antenna for Mining and Tunnel Applications

The HELI-41 is part of the Mini-HELI antenna series, providing medium to high gain performance in a compact form factor. Designed for mining tunnels and industrial applications, this dual-band 2.4 GHz and 5 GHz Wi-Fi antenna radiates in a single direction (uni-directional), making it ideal for targeted coverage in confined spaces. The HELI-41 enhances IoT, telemetry, and mining automation, ensuring seamless connectivity even in challenging underground environments.

Dual-Band Wi-Fi Coverage: Supports both 2.4 GHz and 5 GHz bands for high-performance wireless communication in mining tunnels.
Uni-Directional Radiation Pattern: Focused signal transmission improves coverage and connectivity in specific tunnel areas.
Optimized for High-Density MIMO Deployments: Compatible with 4x4 and 8x8 MIMO configurations using the BRKT-46 mount.
Left-Hand & Right-Hand Circular Polarization: Enhances MIMO performance and RF reliability by reducing interference and improving decorrelation.
Non-Line-of-Sight (NLOS) Propagation: Circular polarization allows signals to navigate around bends and obstacles in tunnels.
Rugged Industrial Design: Engineered for underground deployments, ensuring durability and resistance to environmental disruptions.

The HELI-41 is a robust and efficient Wi-Fi antenna solution for industrial and mining applications, delivering reliable and stable connectivity in complex underground networks.
