Poynting WIFI Antenna 2.4 GHz 17.5dBi Uni-Directional Tunnel Antenna HELI-4is - 15 dB - 2

The combination of the MinePoynt beam antennas for long-range connections through tunnels with this directional antenna leverages Poynting's fifteen years of experience in developing and manufacturing antennas for data networks in underground mining. The tunnel antenna is the ideal solution for wireless 2.4 - 2.5 GHz applications in tunnels. Tests have shown that this antenna achieves both a higher data rate and greater range compared to linearly polarized panel antennas with the same gain. Its robust construction makes this antenna perfect for mining applications. The HELI-4 is a unidirectional antenna, while the closely related HELI-8 is a bidirectional antenna. With the HELI-4, you get a cost-effective network infrastructure to meet current voice and data needs in mines and tunnels.
