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

The HELI-11 forms part of a series of Mini-HELI antennas. These antennas are only mini in size relative to their bigger brothers, the HELI-3, HELI-4 and, HELI-8 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.The HELI-11 is a 2.4 GHz Wi-Fi antenna, radiating in one direction (i.e. Uni-directional), which makes it ideal for the coverage of the 2.4 GHz in mining and other types of tunnels. These antennas are typically used for the deployment of IoT within the tunnel to provide telemetry and mine automation. These antennas are available in both Left Hand Circular (LHC) & Right-Hand Circular (RHC) polarised 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 polarisation difference and spatial diversity, between the two antenna elements, which enhances MIMO performance and RF reliability within a mining tunnel. The 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.SCOPE OF DELIVERYAntenna (left)HIGHLIGHTS• Improved signal propagation and connection stability within a tunnel• Unidirectional - radiates in one direction inside the tunnel• Careful mechanical design provides ruggedness, water and dust resistance • Ideal for M2M and Wi-Fi deployments in mines and tunnelsTECHNICAL DETAILS• 1x WiFi• IP65 outdoor• 12dBi max. 2.4-2.5GHz• RG-141• 400mm N(m)• ceiling mount • MIL-STD 810G/ASTM B117, IK08, UL 94-HBAPPLICATION AREAS• Supplementing fiber/cable networks by providing wireless "hotspots" in areas to improve mobility or extend networks to inaccessible areas such as mines and tunnels• Underground telemetry• Creating full tunnel-based/mine-wide data networks and/or Internet connectivity• Seamless connectivity to personnel via VOIP phones, smart devices, and tablets• M2M applications
