Poynting has fifteen years’ experience in designing and manufacturing antennas for underground mining data networks. The HELI-3is is an Intrinsically Safe antenna with high resistivity non static radome. This antenna is also suitable for oil/gas chemical environments where IS equipment is required. The HELI-3is is a directional antenna. This antenna give 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
