Dual-band tunnel antenna delivering stable Wi-Fi connectivity in harsh underground environments

This circular-polarised, bi-directional antenna is engineered for reliable dual-band Wi-Fi performance in tunnels, mines and industrial corridors. Operating at both 2.4 GHz and 5 GHz, it provides strong signal propagation around bends and in non-line-of-sight conditions, making it ideal for M2M, IoT and automation systems that require dependable connectivity underground. Its rugged IP65-rated construction ensures long-term durability against dust, moisture and vibration.

Key Features

• Dual-band Wi-Fi support: Operates at 2.4 GHz (9 dBic) and 5 GHz (11 dBic) for wide coverage across industrial networks.
• Circular polarisation: Provides both left-hand and right-hand circular polarisation for improved signal stability and penetration.
• Bi-directional radiation: Offers effective coverage in both directions along tunnel environments.
• Enhanced MIMO compatibility: Designed for optimal decorrelation through polarisation and spatial diversity.
• Rugged IP65 enclosure: Protects against dust and water ingress for reliable operation in harsh mining and construction conditions.
• Optimised for M2M, IoT and automation: Suitable for telemetry, mine monitoring and underground communication systems.
• Reliable non-line-of-sight performance: Maintains stable connectivity around bends and in areas with machinery or moving vehicles.

Built for demanding industrial tunnels, this antenna ensures dependable Wi-Fi coverage and robust performance where conventional antennas fail.
