Poynting A-HELI-0018-V3-01-R MINI HELI Circular Polarized Bi-directional; 5- 6 GHz, (1 Port), Max. Gain:11 dBi - (right)

The HELI-18 is part of a series of mini HELI antennas. These antennas are only small compared to their larger brothers, the HELI-3, HELI-4 & HELI-8, but offer medium to high gain, making these antennas ideal for mine tunnels where IoT/M2M connectivity is deployed, and they can also be used for coverage in stops. The HELI-18 is a set of 5 GHz Wi-Fi antennas that radiate in both directions (i.e., bi-directional), making them ideal for 5 GHz coverage in mining and other tunnel types. These antennas are typically used for in-tunnel IoT deployments to enable telemetry and mine automation. These antennas are available with both left-circular (LHC) and right-circular (RHC) polarized antenna elements to provide 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 which improves MIMO performance and RF reliability in a mining tunnel. The Wi-Fi link spreads 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 drilling machines that appear to obscure the tunnel.HIGHLIGHTS - Single port 5 GHz Wi-Fi antenna- This antenna is specially designed for mining and other types oftunnels where rapid network expansion is required- Bidirectional - radiates in both directions in a tunnel- Left and right circular polarized available (for MIMO)- Intrinsically safe version available on requestAPPLICATION AREA- Addition of "hotspots" in areas with fiber/leaky feeder cables toImprove mobility or extend networks to inaccessible areas- Underground telemetry and automation- Creation of complete underground, tunnel-wide data networks and Internet/LTE connectivity- Seamless connectivity to personnel via cell phones and smartdevices and tablets
