The Subterra Wifi (Bi-directional) BT151564

The Subterra Wifi (Bi-directional)

Availablity: Out of Stock
  • Circular Polarised HELI antenna provides enhanced signal propagation ad connection stability within a tunnel
  • Left Hand Circular (LHC) & Right-Hand Circular (RHC) polarised
  • Bi-directional – radiates in both directions in a tunnel
  • Ruggedized, water and dust ingress protected (IP 65)
  • Ideal for Mining & Tunnel M2M and IoT deployment

Circular Polarised, Bi Directional Mine/Tunnel Antenna

The Subterra Wifi offers 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 Subterra Wifi 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.
