Poynting HELI-41 Directional Mine & Tunnel Dual Band Wi-Fi Antenna, Eight Port, 13 dBi

The HELI-41 is a dual-band 2.4 GHz and 5 GHz Wi-Fi antenna, radiating in a single direction (unidirectional), which makes it ideal for coverage of both 2.4 GHz and 5 GHz in mining and other type of tunnels. This antenna is typically used for the deployment of IoT within the tunnel to provide telemetry and mining automation. This solution comes with both Left-hand Circular (LHC) & Right-Hand Circular (RHC) polarized antenna elements (4x HELI-13) to provide optimal decorrelation within a 4×4 MIMO or even 8×8 MIMO deployment when using the BRKT-46, resulting in optimum performance. The optional 20mm roof bolt mounting bracket attachment, BRKT-47, is used in conjunction with BRKT-46 for mounting to standard mine roof bolts.The decorrelation is due to the polarization difference and spatial diversity, between the four 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.

The HELI-41 is part of a series of Mini-HELI antennas by Poynting. These antennas may be mini in size 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.
