The combination of the MinePoynt beam antennas for long haul thru-tunnel links with this directional antenna utilises Poynting’s fifteen years of experience in the design and manufacture of antennas for underground data networks. The HELI-3-IS is an intrinsically safe (IS) antenna with a high impedance, non-static radome. This antenna is also suitable for chemical oil/gas environments where IS equipment is required. HELI-3-IS is a unidirectional antenna, while the closely related HELI-8 is a bidirectional antenna. The HELI-3-IS provides you with a cost-effective network infrastructure for current voice and data requirements in mines and tunnels.
