Poynting 2.4GHz 14dBi High Gain Mine/Tunnel Antenna (PO-HELI-8)

The Poynting PO-HELI-8 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 in an Intrinsically Safe (IS) variant for oil/gas chemical environments, namely the HELI-8IS. 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 polarised 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 whilst the closely related A-HELI-0003 fires in one direction. This antenna gives you a low cost network infrastructure for current voice and data needs in mines and tunnels.
