This 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-0003 is a uni-directional antenna whilst the closely related A-HELI-0008 fires in both directions. An intrinsically safe version of this antenna is available with code A-HELI-0003-IS. This antenna gives you a low cost network infrastructure for current voice and data needs. Future proof since WiFi means low cost devices and well known access for man and machine.
