The HELI-22 is a set of dual 2.4GHz and 5GHz antennas, radiating in both directions (i.e. bi-directional), which make them ideal for the coverage of both 2.5GHz and 5GHz in mining and other type of tunnels. These antennas are typically used for the deployment of IoT within the tunnel to provide telemetry and mine automation.
MAX GAIN: 9 DBI (2.4GHZ) & 11 DBI (5GHZ)
Mining & Tunnelling Antenna
These antennas are available in both Left Hand Circular (LHC) & Right Hand Circular (RHC) polarised antenna elements to provide optimal decorrelation within a MIMO deployment, resulting in the best of the two worlds; decorrelation due to the polarisation differences and also spatial diversity to enhance MIMO performance and RF reliability to service the most severe connectivity within a demanding mining tunnel. The dual-band Wi-Fi connection propagates around tunnel bends in a non-Line of Sight scenario and provides immunity to many of the Wi-Fi signal disrupting objects such as trains and drilling machinery which appear to obscure the tunnel.
