Poynting 42667 - A-HELI-0011-V3-01-R 1x WiFi circular polarised antenna, IP65 outdoor

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

The HELI-11 is part of a series of mini HELI antennas. These antennas are smaller compared to their larger counterparts, the HELI-3, HELI-4, and HELI-8, but offer medium to high gain, making them ideal for mining tunnels where IoT/M2M connectivity is utilized. They can also be used for coverage within the tunnels.

The HELI-11 is a 2.4 GHz Wi-Fi antenna that radiates unidirectionally, making it perfect for covering the 2.4 GHz range in mining and other tunnels. These antennas are typically used for IoT applications in tunnels to enable telemetry and mining automation. They are available with both left-hand circular (LHC) and right-hand circular (RHC) polarized antenna elements to ensure optimal decorrelation within a MIMO deployment, leading to enhanced performance. The decorrelation is due to the polarization difference and spatial diversity between the two antenna elements, which improves MIMO performance and RF reliability in a mining tunnel. The Wi-Fi connection spreads around tunnel curves in a non-line-of-sight scenario and provides immunity to many objects that can disrupt the Wi-Fi signal, such as trains and drilling machines.
