The Poynting HELI-3-IS 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. The HELI-3-IS is an intrinsically safe (IS) antenna with a high resistivity non static radome. This antenna is also suitable for oil/gas chemical environments where IS equipment is required. HELI-3-IS, is a unidirectional antenna whilst the closely related HELI-8 is a bi-directional antenna. The HELI-3-IS gives you a low-cost network infrastructure for current voice and data needs in mines and tunnels.

Product Features:

• The antenna is uni-directional, focusing signal propagation on a single direction.
• It delivers high gain across the 2.4 GHz Wi-Fi band for reliable connectivity.
• Circular polarisation improves performance by reducing multipath interference.
• The device is ideal for mining and tunnelling applications requiring robust signal coverage.
• It offers versatile mounting options for installation on walls, poles, or machinery.
• The intrinsically safe design ensures compliance with hazardous-area standards.

Application Areas:

• It supplements fibre and cable networks by providing wireless hotspots in inaccessible areas such as mines and tunnels.
• The antenna supports underground telemetry systems for real-time monitoring and control.
• It enables the creation of comprehensive tunnel- and mine-wide data networks and internet connectivity.
• It ensures seamless connectivity for personnel using VoIP phones, smart devices, and tablets underground.
• The device is well suited for machine-to-machine (M2M) applications in remote or hazardous environments.
