Navico NAIS-500 AIS with NSPL-500 Splitter and GPS Sensor

Description

Install Class B AIS without adding a separate VHF antenna by using the Navico NAIS-500 AIS Bundle with the NSPL-500 antenna splitter and GPS sensor. The package combines a 2W CSTDMA transponder, external GNSS antenna, and VHF/AIS splitter, helping compatible Simrad, Lowrance, or B&G systems share one properly configured VHF antenna for voice and AIS operation. Need a more complete AIS installation kit for a crowded masthead or hardtop? The NAIS-500 provides NMEA 2000, high-speed NMEA 0183, and USB connectivity for compatible navigation displays.

Key Specifications

• Navico NAIS-500 Class B AIS bundle with NSPL-500 antenna splitter and GPS sensor, part number 000-13609-001.
• 2W Class B CSTDMA AIS transceiver.
• Dual-channel AIS reception across 156.025–162.025 MHz.
• Includes NSPL-500 VHF/AIS antenna splitter and external GPS/GNSS antenna.
• NMEA 2000, high-speed NMEA 0183, and USB interfaces.
• Diagnostic LED status indicators; no built-in AIS target display.
• 9.6V–31.2V DC input with up to approximately 3W AIS transceiver power consumption.
• IPX7 protection for the AIS unit and splitter, subject to proper installation and sealed connections.
• Operating range of -13°F to 131°F (-25°C to 55°C).
• Approximate bundle weight: 1.1 lb (0.5 kg).

Integration

The bundle requires a compatible MFD, chartplotter, PC, or navigation display to show AIS targets. It is not a VHF voice radio, chartplotter, radar, emergency beacon, or collision-avoidance system. The included splitter is intended to share a suitable VHF antenna with a compatible marine VHF radio, but antenna condition, connection type, installation requirements, and product compatibility must be confirmed before use.

AIS targets depend on VHF reception and other vessels transmitting valid AIS information. Before transmitting, program the correct MMSI and accurate vessel static data. U.S. users should confirm registration, radio licensing, and installation requirements before activating the transceiver. [926][928]

Installation Notes

Mount the NAIS-500 and NSPL-500 in a dry, accessible location with appropriate ventilation and cable access. Install the GPS sensor with clear sky view, connect the splitter between the AIS unit, compatible VHF radio, and shared VHF antenna according to the manufacturer diagram, and route RF cables away from high-current wiring.

Use correctly sized 9.6V–31.2V DC wiring and appropriate circuit protection. Confirm NMEA 2000 or NMEA 0183 data output at the chartplotter, then test AIS reception and transmission after programming the MMSI and vessel data.

Before Ordering

Confirm compatible Simrad, Lowrance, B&G, or other NMEA display support; shared VHF antenna compatibility; splitter requirements; GPS sensor placement; MMSI registration; NMEA interface needs; 12V/24V power; and available protected mounting space before ordering.
