HELI-40

The HELI-40-IS adds to our current HELI antenna range for mining and tunnelling deployment. The HELI-40-IS 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. The HELI-40-IS was specifically designed for vehicle/equipment mounting, making it ideal for deployment within the tunnel to provide telemetry and mining automation. The HELI-40-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 antenna comes standard in both Left-Hand Circular (LHC) and Right-Hand Circular (RHC) polarised to provide optimal decorrelation within a MIMO deployment. The polarisation diversity and frequency diversity of the antenna enhances MIMO performance and RF reliability within a mining tunnel. The circular polarisation allows the dual-band Wi-Fi frequencies to propagate around tunnel bends in a non-line-of-sight scenario. This provides improved performance with enhanced link stability and reliability.
