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

Compact tunnel antenna delivering reliable dual-band Wi-Fi for underground systems

This dual-band antenna provides strong and stable 2.4 GHz and 5 GHz Wi-Fi performance in underground tunnels, mining corridors and industrial shafts. Designed for efficient signal propagation in confined and obstructed environments, it supports IoT, telemetry and automation networks where dependable communication is essential. With available left-hand and right-hand circular polarisation options, it offers enhanced decorrelation for MIMO deployments using the BRKT-45, improving overall RF reliability.

Key Features

• Dual-band Wi-Fi capability: Supports both 2.4 GHz and 5 GHz bands for comprehensive underground wireless coverage.
• Circular polarisation options: Available in LHC and RHC variants to improve penetration, stability and MIMO decorrelation.
• Optimised MIMO performance: Polarisation and spatial diversity between the antenna elements enhance signal separation and reduce fading.
• Bi-directional tunnel radiation: Radiates efficiently along the tunnel path for consistent coverage in both directions.
• Reliable underground signal propagation: Performs well in non-line-of-sight conditions common in tunnels with curves, machinery and structural obstructions.
• Rugged IP65 construction: Dust- and water-resistant design supports long-term use in harsh mining and industrial environments.
• Ideal for automation and IoT: Suitable for telemetry, mine automation, smart-device connectivity and sensor networks in underground sites.
• Compact Mini-HELI design: Provides medium-to-high gain performance in a smaller form factor for easy tunnel installation.

Engineered for confined underground spaces, this antenna delivers strong Wi-Fi performance and supports critical communication systems in mining and tunnel operations.
