HELI-13

The HELI-13 forms part of a series of Mini-HELI antennas, which is developed for mining tunnels where IoT/M2M connectivity is deployed and can also be used for coverage into the stopes. The HELI-13-IS is an Intrinsically Safe (IS) antenna with a high resistivity, non-static radome. This antenna is also suitable for oil/gas chemical environments where IS equipment is required. The antenna is also Fire Resistant and Anti-Static (FRAS) compliant, which ensures that the antenna can withstand high temperatures and flames without compromising its functionality and can also be used in environments where static electricity could pose a risk to equipment and personnel.
The HELI-13-IS is a set of dual 2.4GHz and 5GHz antennas, radiating in one direction (i.e. Uni-directional), which make them ideal for the coverage of both 2.4GHz 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 mining automation. These antennas are available in both Left-hand Circular (LHC) and Right-Hand Circular (RHC) polarised antenna elements to provide optimal decorrelation within a MIMO deployment when using the BRKT-45, resulting in the best of the two worlds; decorrelation due to the polarisation difference and 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 Wi-Fi signal-disrupting objects such as trains and drilling machinery which appear to obscure the tunnel.
