Compact dual-band tunnel antenna delivering reliable Wi-Fi connectivity in harsh underground environments

This high-performance Mini-HELI antenna is purpose-built for mining tunnels, construction shafts and underground corridors where stable connectivity is essential. Despite its compact size, it provides medium-to-high gain, strong signal penetration and dependable bi-directional coverage along tunnel paths. With dual-band Wi-Fi support and circular polarisation options, it is ideal for M2M, IoT, telemetry and automation systems operating in demanding subterranean conditions.

Key Features

  • Dual-band Wi-Fi operation: Supports 2.4 GHz and 5 GHz for comprehensive underground network coverage.
  • Bi-directional radiation pattern: Radiates effectively in both tunnel directions for consistent end-to-end coverage.
  • Circular polarisation options: Available in LHC and RHC to enhance MIMO performance and improve link reliability.
  • Optimised MIMO decorrelation: Provides strong spatial and polarisation diversity for improved noise resilience and signal consistency.
  • Four-port configuration: Designed specifically for high-performance mining and tunnel communication systems.
  • Compact Mini-HELI form factor: Small footprint with medium-to-high gain, ideal for tight or restricted tunnel installations.
  • Reliable stope penetration: Capable of extending coverage beyond main tunnels into branching stopes.

Engineered for underground mobility, telemetry and network extension, this antenna enables dependable Wi-Fi and IoT connectivity across complex tunnel infrastructures.
