Poynting HELI-4-IS LH Circular Polarized Directional Mine & Tunnel Wi-Fi Antenna

The HELI-4-IS is a high gain, directional antenna for tunnels and mines. It is an Intrinsically Safe (IS) antenna with a high resistivity non static radome and is suitable for oil/gas chemical environments where IS equipment is required. The HELI-4-IS antenna 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. This antenna gives you a low-cost network infrastructure for current voice and data needs in mines and tunnels.
