Product Overview

The HELI-31 forms part of a series of MiniHELI antennas. These antennas are only mini in size relative to their bigger brothers 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-31 is an ultra-wideband antenna, radiating in one direction (i.e. Uni-directional), which make them ideal for the coverage from 1710-7200 MHz. These antennas are typically used for the deployment of IoT within the tunnel to provide telemetry and mine automation. This wide-band helical antenna propagates around tunnel bends in a Non-Line of Sight scenario and provides immunity to many of the signal disrupting objects such as trains and drilling machinery which appear to obscure the tunnel.
