The SPL2000 allows the boat's VHF antenna to be used for both an AIS and VHF simultaneously. It uses ZeroLoss technology and is suitable for use with AIS Class B transponder systems as well as AIS receivers. It's also designed as a failsafe device with automatic priority given to the connected VHF. It is supplied with a BNC-BNC patch cable for the AIS and a PL259-PL259 cable for the VHF. It also features a AM/FM wired output for an on board stereo receiver. Identical in size to the AIT2000, it makes the perfect complimentary splitter device for Digital Yacht's range of AIS products.
