The combination of the MinePoynt beam antennas for long distance links through tunnels with this directional antenna utilises Poynting’s fifteen years of experience in the design and manufacture of antennas for underground data networks. The tunnel antenna is the ideal antenna for wireless 2.4 – 2.5 GHz applications in tunnels. In tests, this antenna achieved both a higher data rate and a greater range than linearly polarised panel antennas with the same gain. The robust design of this antenna makes it ideal for use in mining applications. HELI-4 is a unidirectional antenna, while the closely related HELI-8 is a bidirectional antenna. The HELI-4 provides you with a cost-effective network infrastructure for current voice and data requirements in mines and tunnels.
