The HELI-22 forms part of a series of Mini-HELI antennas. These antennas are only mini in size relative to their bigger brothers, the HELI-3, HELI-4 & HELI-8, 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.

The HELI-22 is a dual-band 2.4 GHz and 5 GHz Wi-Fi antenna, radiating in both directions (i.e., bi-directional). This makes them ideal for the coverage of both Wi-Fi bands 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. 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 when using the BRKT-45, resulting in optimum performance.

The decorrelation is due to the polarisation difference and spatial diversity, between the two antenna elements, which enhances MIMO performance and RF reliability within a mining tunnel. The dual-band 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.


  • Four-port 2.4 GHz and 5 GHz Wi-Fi antenna
  • This antenna is specially designed for mining and other types of tunnels where rapid extension of network is required
  • Bi-directional – radiates in one direction in a tunnel
  • Left & Right-Hand Circular Polarised

Application Areas:

  • Supplementing fiber/leaky feeder cable “Hotspots” to areas to enhance mobility or extend networks to inaccessible areas
  • Underground telemetry and automation
  • Creating of complete underground in tunnel wide data networks and internet/LTE connectivity
  • Seamless connection to personnel using cellular phones and smart devices and tablets
