Poynting has fifteen years’ experience in designing and manufacturing antennas for underground mining data networks. The HELI 8 tunnel antenna is the ideal antenna for 2.4-2.5 GHz wireless applications in tunnels. In tests, both the data rate and range achieved with this antenna was greater than obtained when using linearly polarized panel antennas of the same gain. The hardy construction of this antenna makes it ideal for the mining environment. A-HELI-0008 is a Bi directional antenna. This antenna gives
you a low cost network infrastructure for current voice and data needs in mines and tunnels.

Application Areas:

•  Supplementing fibre/cable networks by providing wireless “Hotspots” to areas to enhance mobility or extend networks to inaccessible areas such as mines and tunnels
•  Underground telemetry
•  Creation of complete in tunnel/mine wide data networks and or internet connectivity
•  Seamless connection to personnel using VOIP phones, smart devices and tablets
•  M2M applications
