Poynting HELI-19 Bi-Directional Mine & Tunnel Dual Band Wi-Fi Antenna, 2.4/5.0 GHz, 11 dBi

The HELI-19 is a dual-band 2.4 GHz and 5 GHz Wi-Fi antenna, radiating in both directions (bi-directional). This makes it ideal for the coverage of both Wi-Fi bands 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. It is available in both Left Hand Circular (LHC) & Right-Hand Circular (RHC) polarized antenna elements to provide optimal decorrelation within a MIMO deployment when using the BRKT-45, 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. 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-19 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.
