Poynting HELI-11 Circular Polarized Directional Mine & Tunnel Wi-Fi Antenna, 2.4 GHz

Poynting HELI-11 Directional Mine & Tunnel Wi-Fi Antenna, 2400 - 2500 MHz, 12 dBi

The HELI-11 is a 2.4 GHz Wi-Fi antenna, radiating in one direction (unidirectional), which makes it ideal for coverage of 2.4 GHz in mining and other types of tunnels. This antenna is typically used for the deployment of IoT within the tunnel to provide telemetry and mine automation. It is available in both Left Hand Circular (LHC) & Right-Hand Circular (RHC) polarized antenna elements to provide optimal decorrelation within a MIMO deployment when using BRKT-45, resulting in the best of two worlds; decorrelation due to the polarization difference and spatial diversity to enhance MIMO performance, and RF reliability to service the most severe connectivity within a demanding mining tunnel. The Wi-Fi connection propagates around tunnel bends in a non-line of sight scenario and provides immunity to many Wi-Fi signal disrupting objects such as trains and drilling machinery which appear to obscure the tunnel.

The HELI-11 is part of a series of Mini-HELI antennas by Poynting. These antennas may be mini in size but offer medium to high gain, which makes these antennas ideal for mining tunnels where IoT/M2M connectivity is deployed and can also be used for coverage into the stopes.
