The B20G-N-AIS is a high-performance omnidirectional AIS collinear antenna designed for reliable operation across the marine Automatic Identification System (AIS) band at 161.975-162.025 MHz. Engineered for continuous-duty maritime communication, it supports both AIS1 and AIS2 channels, enabling accurate transmission and reception of critical vessel data including position, heading, speed, and identification information. Built as a precision-tuned collinear array antenna, the B20G-N-AIS delivers a stable 5.1 dBi gain, providing extended range and consistent 360-degree coverage for vessel-to-vessel and vessel-to-shore AIS communication networks. This ensures reliable situational awareness and tracking performance in busy coastal, harbour, and offshore environments where signal clarity and continuity are essential for maritime safety and navigation systems. Constructed for durability in harsh marine conditions, the antenna is designed to withstand continuous exposure to salt air, extreme wind loading, and environmental stress typical of coastal and offshore installations. With a 50W power handling capability, it is suited to professional AIS transceiver systems requiring stable long-term performance. The antenna is fitted with an N-type female connector, ensuring secure RF connection and compatibility with standard marine-grade coaxial feed systems. At 3.2 metres in length, the B20G-N-AIS is optimised for elevated installation on vessel masts, bridge roofs, and fixed coastal infrastructure, where height is critical for maximising line-of-sight range and system effectiveness. As part of the ZCG Scalar marine antenna range, the B20G-N-AIS provides a dependable AIS collinear antenna solution for commercial shipping, fishing fleets, port infrastructure, and maritime safety networks, delivering consistent performance and robust reliability in demanding marine communication environments.
