Poynting HELI-6, Directional, Circular-Polarised Tunnel, 4G/LoRa antenna; 698 to 960 MHz

High-gain LTE tunnel antenna engineered for long-range underground connectivity

This rugged directional antenna is purpose-built for mining tunnels, industrial shafts and harsh underground environments requiring stable LTE communication. Operating from 698–960 MHz, it delivers significantly improved range and data performance compared to similar-gain linear panel antennas. Designed with circular polarisation for superior signal propagation around bends and obstructions, it supports reliable M2M, IoT and telemetry applications across mining, oil, gas and chemical facilities.

Key Features

• High-gain directional performance: Optimised for long-range LTE communication in tunnels and underground corridors.
• Circular polarisation: Enhances signal penetration, stability and non-line-of-sight performance in confined spaces.
• Wide compatibility: Covers 868/915 MHz ISM bands for LoRa, telemetry and other sub-GHz technologies.
• Uni-directional radiation: Focuses energy in one direction along the tunnel for improved reach and reduced interference.
• Rugged IP65 construction: Water- and dust-resistant enclosure suitable for mining, oil, gas and chemically harsh environments.
• Proven underground reliability: Outperforms equivalent linear antennas in range and throughput during field testing.
• Flexible deployment: Ideal for underground M2M, IoT networks, remote monitoring and mining automation systems.
• Connector ready: Uses N-Type (F) interface; cable sold separately.

This antenna provides dependable, high-performance connectivity where robust and long-distance signal delivery is critical in underground operations.
