This tunnel antenna is the ideal antenna for users working with 2.4-2.5 GHz wireless applications in tunnels. Tests have shown that both the data rate and the range achieved with this antenna are greater than using linearly polarized panel antennas with the same gain.
For mining workers, it offers an ideal rugged construction. A-HELI-0003 is a unidirectional antenna, while the closely related A-HELI-0008 goes in both directions.
