Poynting HELI-4 Circular Polarized Directional Mine & Tunnel Wi-Fi Antenna, 14.5 dBi

Poynting HELI-4 High Gain Directional Mine & Tunnel Antenna, LH Circular Polarized

The HELI-4 is a high gain, directional antenna for tunnels and mines. It is ideal for 2.4 - 2.5 GHz wireless applications. In tests, both the data rate and range achieved with this antenna was greater than obtained when using linearly polarized panel antennas of the same gain. The hardy construction of this antenna makes it ideal for the mining environment. This antenna gives you a low-cost network infrastructure for current voice and data needs in mines and tunnels. If Intrinsically Safe (IS) equipment is required please see the HELI-4-IS version of this antenna.
