The HELI-8 is a high gain bi-directional antenna that complements our Wi-Fi MinePoynt tunnelling and mining antennas. The combination of the MinePoynt beam antennas for long-range tunnel links with this directional antenna utilises Poynting’s fifteen years of experience in the design and manufacture of antennas for underground data networks. This antenna is also suitable for chemical environments in the oil and gas industry where IS equipment is required. The HELI 8 tunnel antenna is the ideal antenna for wireless 2.4 – 2.5 GHz applications in tunnels. In tests, this antenna has 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-8 is a bidirectional antenna, while the closely related HELI-3 transmits in one direction only. This antenna provides you with a cost-effective network infrastructure for current voice and data requirements in mines and tunnels.
