Poynting 2.4GHz 15dBi High Gain Intrinsically Safe Mine/Tunnel Antenna (PO-HELI-4is)

The Poynting PO-HELI-4is compliments Poyntings WiFi 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. 

Poynting PO-HELI-4is Key Features

  • Circular polarised helical antenna
  • WiFi compatible
  • Uni-directional 
  • Ruggedised 
  • Future proof
  • Proven antenna performance giving maximum range in all directions 
  • Ideal where the other devices used polarisation could change 
  • High gain over the 2400 MHz WiFi band 
  • Intrinsically Safe with high resistivity non static radome 
  • Versatile installation mounting options 
  • Lightweight

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 polarised 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.
