Poynting 42662 - A-HELI-0022-V3-02 2x 2x2 Dual-Band WiFi circular polarised antenna I

Poynting A-HELI-0022-V3-02 (2x) 2x2 Dual-Band WiFi Circularly Polarized Antenna, IP65 Outdoor, 9dBi max. 2.4-2.5GHz and 11dBi max. 5-6GHz, 400mm N(m)

The HELI-22 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 they 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-22 is a dual-band Wi-Fi antenna for 2.4 GHz and 5 GHz that radiates in both directions (i.e., bi-directional). This makes it ideal for covering both Wi-Fi bands 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, resulting in optimal performance. The decorrelation is due to the polarization difference and spatial diversity between the two antenna elements, which enhances MIMO performance and RF reliability in a mining tunnel. The dual-band Wi-Fi connection propagates around tunnel curves in a non-line-of-sight scenario and provides immunity against many objects that disrupt Wi-Fi signals, such as trains and drilling machines.

Delivery includes:

• Antenna, 2 mounting brackets

Highlights:

• Enhanced signal propagation and connection stability within a tunnel
• Unidirectional - radiates in one direction within the tunnel
• Careful mechanical design ensures robustness, water, and dust resistance
• Ideal for M2M applications.
