Poynting HELI-13-LEFT, Left-Hand Circular-Polarised Tunnel, Dual Band WiFi antenna, 2400 to 6000 MHz

Compact tunnel antenna delivering stable dual-band Wi-Fi connectivity underground

This dual-band tunnel antenna provides reliable 2.4 GHz and 5 GHz Wi-Fi performance for underground communication, making it ideal for IoT, telemetry and mine automation systems. Its circular polarisation enhances signal stability and propagation in confined spaces, while the bi-directional radiation pattern supports consistent coverage along tunnel pathways. With options for LHC and RHC polarisation, it offers strong decorrelation for MIMO deployments when paired with the BRKT-45, improving RF reliability in challenging industrial environments.

Key Features

• Dual-band Wi-Fi operation: Supports 2.4 GHz and 5 GHz for comprehensive underground coverage.
• Circular polarisation options: Available in LHC and RHC for improved stability and MIMO decorrelation.
• Bi-directional tunnel performance: Radiates effectively in one direction along the tunnel path.
• Enhanced MIMO compatibility: Polarisation and spatial diversity improve performance in multi-antenna systems.
• IP65 rugged construction: Resistant to dust, moisture and harsh mining conditions.
• Optimised for IoT and automation: Suitable for telemetry, mine automation and underground data networks.

Built for demanding underground environments, this antenna delivers consistent, high-quality Wi-Fi connectivity for industrial, mining and tunnel-based communication systems.
