Poynting HELI-40 Bidirectional Dual Band Wi-Fi Antenna for Mines & Tunnels, 4.8 dBi

The HELI-40 is a dual-band 2.4 GHz and 5 GHz Wi-Fi antenna, radiating in both directions. This makes it ideal for coverage of both Wi-Fi bands in mining and other types of tunnels. It was specifically designed for vehicle/equipment mounting to be used for deployment to provide telemetry and mining automation.

The antenna is 2×2 MIMO and comes standard with both Left-Hand Circular (LHC) and Right-Hand Circular (RHC) polarization to provide optimal decorrelation within the MIMO deployment. The polarization diversity and frequency diversity of the antenna enhances MIMO performance and RF reliability within a mining tunnel. The circular polarization allows the dual-band Wi-Fi frequencies to propagate around tunnel bends in a non-line of sight scenario. This provides improved performance with enhanced link stability and reliability.
