A-HELI-0004

High-Gain Uni-Directional Antenna for Underground Mining Networks

The HELI-4 is a high-gain, uni-directional antenna designed to complement Poynting’s Wi-Fi MinePoynt tunnel and mine antenna solutions. With over fifteen years of expertise in underground mining data networks, this antenna is optimized for long-distance thru-tunnel communication when used alongside MinePoynt beam antennas. Engineered for **2.4 - 2.5 GHz wireless applications**, the HELI-4 delivers superior data rates and extended range compared to conventional linearly polarized panel antennas of the same gain.

Optimized for Tunnel Communications: Provides reliable and extended wireless connectivity in underground mining environments.
High-Gain Performance: Enhances data transmission and network reliability in challenging underground conditions.
Uni-Directional Design: Focuses signal strength for long-distance thru-tunnel communication.
Rugged and Durable Construction: Built to withstand harsh mining conditions, ensuring longevity and reliability.
Compatible with MinePoynt Beam Antennas: Works seamlessly with MinePoynt antennas for extended-range connectivity.
Alternative Bi-Directional Model: The HELI-8 provides bi-directional coverage for applications requiring signal distribution in both directions.
Cost-Effective Network Solution: Provides a low-cost infrastructure for underground voice and data communication.

The HELI-4 is an ideal choice for mining and tunnel applications, offering a reliable, high-performance, and cost-effective solution for underground wireless communication networks.
