The HELI-8 is a high gain, directional antenna, which complements our Wi-Fi MinePoynt tunnel and mine antennas. The combination of MinePoynt beam antennas for long distance thru-tunnel links with this directional antenna, exploits Poynting’s fifteen years’ experience in designing and manufacturing antennas for underground mining data networks. This antenna is also suitable for oil/gas chemical environments where IS equipment is required. The HELI 8 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. HELI-8 is a bi-directional antenna whilst the closely related HELI-3 fires in one direction. This antenna gives you a low-cost network infrastructure for current voice and data needs in mines and tunnels.

• Circular Polarised HELI antenna provides enhanced signal propagation and connection stability within a tunnel
• Circularly polarised
• Bi-directional – radiates in both directions in a tunnel
• Careful mechanical design provides ruggedness, water and dust resistance (IP 65)
• Ideal for Mining & Tunnel M2M and IoT deployments
