Poynting HELI-42 Circular Polarised 4x4 MIMO Bi-Directional Mine/Tunnel WiFi Antenna

Description::

High-gain dual-band tunnel antenna delivering stable circular-polarised Wi-Fi connectivityThis compact Mini-HELI antenna system provides strong reliable Wi-Fi coverage in underground tunnels mining corridors and industrial shafts. Supporting both 2.4 GHz and 5 GHz bands it uses circular polarisation and a bi-directional radiation pattern to ensure consistent connectivity along tunnel paths even around bends or in non-line-of-sight conditions. Designed for demanding IoT M2M telemetry and automation networks it offers medium-to-high gain performance and enhanced MIMO decorrelation when deployed as a multi-antenna system.Key FeaturesDual-band Wi-Fi performance: Supports 2400–2500 MHz (9.5 dBic) and 5000–6000 MHz (13 dBic) for comprehensive underground coverage.Circular polarisation: Available in both LHC and RHC for improved penetration stability and MIMO decorrelation.Bi-directional radiation: Radiates effectively in both directions along a tunnel for uniform coverage.Enhanced MIMO deployment: Works seamlessly in 4×4 or 8×8 MIMO configurations when paired with the BRKT-46 mounting bracket.Strong non-line-of-sight performance: Maintains connectivity around bends and through obstructions such as vehicles trains and mining machinery.Rugged IP65 design: Dust- and water-resistant construction suitable for harsh underground and industrial environments.Ideal for IoT and automation: Commonly used for telemetry mine automation and wide-area underground data networks.This antenna system provides dependable high-gain tunnel coverage with advanced polarisation diversity making it ideal for mining operations requiring robust Wi-Fi and IoT communication.Improving WIFI in your Mine or Tunnel using Poynting's HELI Antennas Read more
