Poynting HELI-22 Bi-Directional Mine & Tunnel Dual Band Wi-Fi Antenna, Four Port, 11 dBi

The HELI-22 is a dual-band, four port, Wi-Fi antenna, radiating in both directions (bi-directional), 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 mine automation. This solution comes with both the Left Hand Circular (LHC) & Right-Hand Circular (RHC) polarized antenna elements (2x HELI-19) to provide optimal decorrelation within a MIMO deployment resulting in optimum performance. The decorrelation is due to the polarization difference and spatial diversity, between the two antenna elements, which enhances MIMO performance and RF reliability within a mining tunnel. A mounting option, using the BRKT-47 roof bolt mounting bracket attachment, in conjunction with BRKT-45 (included), allows this antenna to be mounted to standard mine roof bolts. 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-22 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.
