Underground communication systems perform a vital role in the safety & productivity of mining and tunnelling operations. Modern underground operations use communication systems to enable secure voice communications, locate both people and machinery, remote control of vehicles and systems, as well as site access and security. A crucial component of the underground communication system is the antenna; a specialized antenna can enhance wireless connectivity significantly.

Poynting Antennas has a long history of designing and supplying
specialist antennas for mining and tunnel communication systems in various mines and tunnels. We manufacture a complete Wi-Fi and LTE range of antennas that are used in mines internationally. Especially our circular polarised helical antenna range.



The HELI series are circular polarised antennas that are specifically designed for mining & tunnelling applications. The antennas cover the popular Wi-Fi bands, namely the 2.4 GHz & 5 to 6 GHz bands with varying gains.

The HELI antennas are typically used for the deployment of IoT within the tunnel to provide telemetry and mining automation.

The HELI series comes in varying sizes depending on the deployment requirements. The robust mechanical enclosure design of the HELI series features an IP65 rating which ensures that the antennas are weather, dust and vandal resistant making them suitable for harsh environments.
