Poynting A-HELI-0031-V2-01-L Wideband 5G/LTE/WiFi Tunnel Antenna – Left Circulating – Gray
Overview
The HELI-31 is part of a series of MiniHELI antennas. These antennas are only mini compared to their bigger brothers, making them antennas ideal for mine tunnels where IoT/M2M connectivity is used, and can also be used for coverage in the tunnels. The HELI-31 is an ultra-wideband antenna that radiates in one direction (i.e. unidirectional), making it ideal for coverage from 1700-7200 MHz. These antennas are typically used for the deployment of IoT in tunnels to enable telemetry and mine automation. This broadband helical antenna propagates around tunnel curves in a non-line-of-sight scenario and provides immunity to many signal-jamming interfering objects such as trains and drilling machines that appear to obscure the tunnel.
Properties
- Ultra-wideband antenna from 1700 – 7200 MHz.
- Peak gain of 9.5 dBi over the 1700 – 7200 MHz range.
- Proven antenna performance for maximum range.
- Unidirectional – radiates in one direction only.
- Left and right circular polarized available (for MIMO).
- Intrinsically safe version available on request.
Areas of application
- Addition of fiber/cable networks “hotspots” in areas to improve mobility or extend networks to inaccessible inaccessible areas such as mines and tunnels.
- Underground telemetry.
- Construction of complete underground, tunnel-wide data networks and Internet/LTE and Wi-Fi connectivity.
- Seamless connection to staff via cell phones
- and smart devices and tablets
