Poynting Heli Series

The HELI series comprises circular polarized antennas specifically crafted for applications in mining and tunnelling. These antennas are designed to cover the widely used Wi-Fi bands, namely the 2.4 GHz and 5 to 6 GHz bands, offering different gains. Primarily employed in tunnel environments, the HELI antennas play a crucial role in deploying IoT technology, enabling telemetry and mining automation.

To cater to diverse deployment needs, the HELI series is available in various sizes. The antennas are housed within a sturdy mechanical enclosure designed to withstand demanding conditions, boasting an IP65 rating. This exceptional rating ensures the antennas’ resilience against weather elements, dust, and acts of vandalism, making them exceptionally suitable for harsh environments.

Product Type: Antenna Heli-22

The HELI-22 is a compact antenna from the Mini-HELI series. It offers medium to high gain, making it ideal for IoT/M2M connectivity in mining tunnels. The dual-band (2.4 GHz and 5 GHz) antenna provides coverage in both Wi-Fi bands and is available in Left Hand Circular (LHC) and Right-Hand Circular (RHC) polarizations. It ensures optimal decorrelation in MIMO deployments, enhancing performance and RF reliability in mining tunnels, even around bends and in Non-Line of Sight scenarios.

Antenna Heli-22 Key Features:

  • Polarization: Circular Polarised (LHC or RHC)
  • Bidirectional: radiates in both directions in a tunnel
  • Frequency bands: 2400-2500 MHz; 5000-6000 MHz
  • Gain (max): 2.4 GHz 10dBi; 5 GHz 11.5dBi
  • Ruggedized water and dust ingress protected (IP 65)
  • Fire Resistant

Product Type: Antenna Heli-8

The HELI-8 is a high-gain, bi-directional antenna designed for wireless applications in tunnels. The Heli-8 offers superior performance in data rate and range compared to linearly polarized panel antennas of the same gain. Its rugged construction makes it suitable for mining environments. The HELI-8 providing a cost-effective network infrastructure for voice and data communication needs in mines and tunnels.

Antenna Heli-8 Key Features:

  • Polarisation: Left-Hand Circular
  • Bi-directional – radiates in both directions in a tunnel
  • Frequency bands: 2400-2500 MHz
  • Gain (max): 14.5 dBi
  • Ruggedized, water and dust ingress protected (IP 65)
  • Fire Resistant

Product Type: Antenna Heli-3

The HELI-3 is a high gain, uni-directional antenna that leverages Poynting’s extensive experience in designing antennas for underground mining data networks. This antenna is ideal for 2.4-2.5 GHz wireless applications in tunnels, outperforming linearly polarized panel antennas in both data rate and range. Its rugged construction suits the mining environment. The HELI-3 provides a cost-effective network infrastructure for voice and data communication in mines and tunnels. An intrinsically safe version, HELI-3-IS, is also available.

Antenna Heli-3 Key Features:

  • Polarisation: Left-Hand Circular
  • Uni-directional – radiates in one direction in a tunnel
  • Frequency bands: 2400-2500 MHz
  • Gain (Max) 17.5 dBi
