• Circular Polarised HELI antenna provides enhanced signal propagation and connection stability within a tunnel
• Covers LTE frequency band 10 from 1710 – 2170 MHz
• Uni-directional – radiates in one direction in a tunnel
• Ruggedized & water ingress protected
• Ideal for Mining & Tunnel M2M and IoT deployments

The HELI-5 is a high gain, uni-directional antenna for LTE applications, which complements our MinePoynt mine and tunnel 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 communication and data networks. This antenna is also suitable for oil/gas chemical environments where IS equipment is required. In tests the data rate and range achieved with this antenna was greater than those obtained when using linear polarised panel antennas of the same gain. The hardy construction of the antenna makes it ideal for a mining environment. The HELI-5 operates from 1710 MHz – 2170 MHz while the HELI-6 operates from 698 – 960 MHz.
