Under & Above Ground Connectivity

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.



The OMNI-700 series antennas, form part of our latest “POYNTING Rhyno” antenna range and offer a small profile antenna for use in the IoT/M2M, Smart Meter, Smart Utilities, and Industrial markets.

The OMNI-700 antenna series offers various configurations for covering the popular Wi-Fi frequency bands namely, the 2.4 GHz and 5 to 6 GHz bands with gains varying from 4 to 8 dBi. The OMNI-700 series antennas were specifically designed to be rugged and ideal for operation in harsh environmental conditions.

The series features an IP69K protection rating, which indicates that the antennas are dustproof and protected against high pressure, high temperature spray downs at close range. It also features an IK10 impact rating, making the antennas ideal for industrial IoT/M2M and mining applications.



Poynting’s PUCK series offers a small profile antenna for use in the mining & tunneling markets. The PUCK series offers a variety of options for MIMO LTE/5G (617 to 4200 MHz), MIMO Wi-Fi (dual band 2.4 GHz & 5 to 6 GHz) and GPS/GLONASS within the same enclosure, while keeping implementation as simple as possible with its many mounting options.

Where the XPOL-1-5G is an omni-directional antennas, while the XPOL-2-5G is a uni-directional antenna. The XPOL-1-5G antenna offer wideband performance from 617 to 4200 MHz, covering contemporary LTE/5G frequency bands, with a peak gain of 6 dBi across the band. The antenna also offers 2×2 MIMO and 4×4 MIMO for improved performance.

The XPOL-2-5G antennas, which are uni-directional, offer exceptional performance and wideband coverage from 617 to 3800 MHz with 2×2 MIMO performance. Due to the uni-directional radiation pattern, the antennas achieve a peak gain of 11 dBi within a single direction. The XPOL-2-5G series covers popular LTE/5G frequency bands for future proof deployment. The radiation patterns of the XPOL-5G series are exceptionally well controlled, further adding to the performance of the antennas. The robust mechanical enclosure design of the XPOL-5G series ensures that the antennas are weather, dust and vandal resistant and give it an IP65 rating, suitable for harsh environments.
