Product manual: The product manual is this document and should be read thoroughly prior to any attempt to install or use the NSPL-500.
VHF radio connection cable. This cable is used to connect a VHF radio to the NSPL-500. The cable has PL259 connectors at either end and requires a SO239 connector on the VHF radio. If your VHF radio does not have a SO239 connector please contact your dealer for details of suitable adaptors.
AIS transceiver connection cable: This cable is used to connect a Class-B AIS transceiver, such as the NAIS-500 to the NSPL-500. The cable has a BNC connector at one end (for connection to the NSPL-500) and a PL259 connection at the opposite end (for connection to the AIS transceiver).
NSPL-500 AIS/VHF antenna splitter unit. The NSPL-500 has a number of indicators which provide information to the user about the status of the NSPL-500.
Power and FM cable. The power and FM cable connects to the NSPL-500 and enables connection to power and an FM radio antenna input.
Save the hassle of installing a costly second antenna and use your existing single antenna with VHF/AIS/FM, by enlisting the lightweight, compact NSPL 500 antenna splitter.
When combined with the NAIS 500 AIS system, you can see and be seen on the water, whether tackling busy shipping lanes or crowded ports.
