Poynting HELI-12 Circular Polarised, Uni-Directional Mine/Tunnel Antenna, Wi-Fi 5000 - 6000 MHz, 13dBic

The HELI-12 forms part of a series of Mini-HELI antennas. These antennas are only mini in size relative to their larger counterparts, the HELI-3, HELI-4, and HELI-8, but offer medium to high gain. This makes them ideal for mining tunnels where IoT/M2M connectivity is deployed, and they can also be used for coverage into stopes.

The HELI-12 is a 5 GHz Wi-Fi antenna, radiating in one direction (uni-directional), which makes it suitable for 5 GHz coverage in mining and other tunnel environments. These antennas are typically used for IoT deployments within tunnels to provide telemetry and support mine automation.

These antennas are available in both Left-Hand Circular (LHC) and Right-Hand Circular (RHC) polarised antenna elements. This enables optimal decorrelation within a MIMO deployment when used with the BRKT-45, resulting in improved performance. The decorrelation is achieved through differences in polarisation and spatial diversity between the two antenna elements, which enhances MIMO performance and RF reliability within mining tunnels.

The Wi-Fi signal propagates around tunnel bends in non-line-of-sight scenarios and provides improved resilience against common signal-obstructing objects such as trains and drilling machinery that may appear to block the tunnel.
