Marine AIS antennas are specialized devices used to transmit and receive Automatic Identification System signals for vessel tracking and collision avoidance. These antennas enhance communication between ships and coastal stations, ensuring real-time data exchange for safer navigation. They are essential for modern marine navigation systems, improving situational awareness and maritime safety.

Marine AIS Antennas: Frequency Range: 156-162 MHz, Gain: 3-6 dB, VSWR: ≤1.5:1, Impedance: 50 Ohms, Connector Type: SO-239 (PL-259), Material: Fiberglass or Stainless Steel, Height: 1-4 meters, Operating Temperature: -30°C to +70°C, Waterproof Rating: IPX6/IPX7.

Marine Navigation: GPS Accuracy: 1.5-3 meters, GNSS Support: GPS, GLONASS, Galileo, Beidou, Display Size: 5-16 inches, Resolution: 800x480 to 1920x1080, Power Supply: 12-24V DC, Operating Temperature: -15°C to +55°C, Waterproof Rating: IPX7/IPX8, Material: Polycarbonate or Aluminum.

Buoyancy: Foam or Polyethylene, Density: 30-50 kg/m³, Flotation Capacity: 5-50 kg, Material: Closed-cell foam or PVC, Operating Temperature: -40°C to +80°C.

Material Grades: Stainless Steel (316L), Aluminum (6061-T6), Fiberglass (E-Glass), Polycarbonate (Lexan), Polyethylene (HDPE).

Viscosity: Not typically applicable to antennas/navigation systems, but for marine lubricants: 10W-40, 15W-40, or SAE 30.

Marine AIS Antennas and Marine Navigation products typically comply with international maritime standards such as IEC 60945, IEC 62288, and ITU-R M.1371 for AIS functionality.
