Poynting A-HELI-0011-V3-01-L 1x WiFi circular polarized antenna, IP65 outdoor, 12dBi max. 2.4-2.5GHz, 400mm N(m), left

The HELI-11 is part of a series of mini HELI antennas. These antennas are small in size compared to their larger brothers, the HELI-3, HELI-4 and HELI-8, but offer medium to high gain, making these antennas ideal for mine tunnels where IoT/M2M connectivity is used, and can also be used for in-tunnel coverage.
The HELI-11 is a 2.4GHz Wi-Fi antenna that radiates in one direction (i.e. unidirectional), making it ideal for covering the 2.4GHz range in mining and other tunnels. These antennas are typically used for IoT deployment in tunnels to enable telemetry and mine automation. These antennas are available with both left circular (LHC) and right circular (RHC) polarized antenna elements to ensure optimal decorrelation within a MIMO deployment when using the BRKT-45, resulting in optimal performance. The decorrelation is due to the polarization difference and spatial diversity between the two antenna elements, improving MIMO performance and RF reliability in a mine tunnel. The Wi-Fi connection extends around tunnel curves in a non-line-of-sight scenario, providing immunity to many objects that interfere with the Wi-Fi signal, such as trains and drills that appear to obscure the tunnel.
