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-0008 is a Bi-directional antenna whilst the closely related A-HELI-0003 fires in one direction.
