Navico NSPL-500 VHF/AIS Antenna Splitter (000-13612-001)

Navico NSPL-500 VHF/AIS Antenna Splitter (000-13612-001)

The Navico NSPL-500 (Part Number: 000-13612-001) is a high-performance, compact Active VHF/AIS Antenna Splitter designed for seamless integration across Simrad, B&G, and Lowrance marine electronics systems. It allows a single marine VHF antenna to be shared simultaneously between a VHF radio transceiver, a Class B AIS transponder/receiver, and an onboard AM/FM entertainment stereo without signal degradation or risk of RF damage.

Engineered with advanced active circuitry, the NSPL-500 delivers zero insertion loss on VHF reception and low insertion loss on VHF transmission. In the event of power loss, its fail-safe auto-routing design automatically prioritizes the VHF marine radio connection to maintain emergency VHF distress calling capabilities.

Key Features

• Active Antenna Splitting: Enables a single VHF antenna to simultaneously serve VHF radio, AIS transponder, and AM/FM stereo head units.

• Zero Insertion Loss: Active internal amplification eliminates signal attenuation across VHF receive channels.

• VHF Override Priority & Fail-Safe: Smart transmit priority circuit protects AIS/FM circuitry during VHF broadcasts and automatically routes VHF to the antenna during power outages.

• Low Power Consumption: Optimized low-current draw (< 150 mA at 12 V DC) suitable for sailboat and motor vessel electrical systems.

• Compact & Rugged Enclosure: IPX7 waterproof housing with light weight footprint allows easy bulk-head mounting in tight helm quarters.
