The HELI-41 is part of POYNTING’s Mini-HELI antenna series and is designed to deliver dependable dual-band 2.4 GHz and 5 GHz Wi-Fi connectivity within mining tunnels and similar environments. Although compact compared to larger models such as the HELI-3, HELI-4, and HELI-8, the HELI-41 offers medium to high gain and is ideal for coverage into stopes and tunnel spaces. Its uni-directional radiation pattern ensures focused coverage in a single direction, making it highly effective for mining IoT, telemetry, and automation.

Dual-Band Wi-Fi Antenna: Supports both 2.4 GHz and 5 GHz bands, enabling seamless communication for a variety of devices in underground environments.
Uni-Directional Coverage: Focuses the signal in one direction for efficient propagation in confined tunnel spaces and stopes.
MIMO-Enhanced Performance: Available in Left-Hand Circular (LHC) and Right-Hand Circular (RHC) polarisation options to optimise performance in 2×2 or 4×4 MIMO deployments using the BRKT-46 mount.
Reliable NLOS Propagation: Dual-band signal travels around tunnel bends and obstructions such as mining vehicles and equipment.
Improved RF Stability: Polarisation and spatial diversity help reduce interference, ensuring reliable connectivity even in harsh environments.
Compact and Robust: Built for the demands of underground applications while maintaining a smaller form factor for flexible installation.

The HELI-41 is a highly effective solution for underground networks, delivering reliable Wi-Fi performance to support mining automation, IoT deployments, and personnel communication in tunnels and other industrial environments.
