Product Overview

This high gain directional antenna compliments our Wi-Fi MinePoynt tunnel and mine antennas. The combination of MinePoynt beam antennas for long distance thru-tunnel links with this directional antenna, exploits Poynting’s fifteen years’ experience in designing and manufacturing antennas for underground mining data networks. This antenna is also suitable for oil/gas chemical environments where IS equipment is required. The 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. This antenna gives you a low cost network infrastructure for current voice and data needs in mines and tunnels.


  • Proven antenna performance giving maximum range in all directions
  • Ideal where the other devices used polarisation could change
  • High gain over the 2400 MHz Wi-Fi band
  • Versatile installation mounting options
  • Lightweight

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
  • Extension/deployment of wireless connectivity on oil rigs, refinery, factories where intrinsically safe equipment is required
