AIS / VHF / FM Antenna Splitter (SP160)

Many AIS splitters introduce significant signal loss, some say no loss but this unique Vesper Marine splitter is the only one that provides signal gain - improving AIS reception and increasing range. This is because the Vesper Marine splitter has a built-in low noise amplifier. This is especially important to increase the receive range from the increasing number of low power AIS SART and MOB devices.

Key Features

AIS Sensitivity Gain - The SP160 provides amplification to the AIS signal resulting in much higher AIS sensitivity, improving AIS receive range.
Low power consumption - Very low power consumption designed to save your battery power.
Simple connections - No adapters or special patch cords needed for VHF/AIS. Uses standard PL-259 patch cables (two 2m (6.5ft) cables included).
Easy installation - Very compact and easy to install with built-in mounting flanges.
LED status indicators - 4 status LED's (power, VHF transmit, AIS transmit, antenna quality).
AM and FM radio connection - Provides AM/FM radio connection. An optional cable with a standard "Motorola plug" is available to make installation easy. Plugs directly into almost all car or marine stereos.
VHF-in-use indicator - VHF-in-use indicator appears on the screen of the AISWatchMate 850 and WatchMate Vision AIS transponders whenever the VHF radio is being used. This unique feature indicates when AIS traffic is delayed due to the antenna being in-use by the VHF radio and is also an excellent indicator if a stuck-mic condition exists.
Fail-safe VHF priority - VHF radio always has priority and the VHF can always transmit even if the power to the splitter fails.
Antenna quality monitor indicates if there is a problem - The unique antenna quality LED will indicate a problem with the antenna, cable or installation.
12 or 24 Volt supply - Designed to work with either 12 or 24 volt supply.
Waterproof - IPx7 rated. High quality rugged construction made specifically for marine use.

Benefits

High performance - The Vesper Marine SP160 Splitter has higher performance than any other AIS splitter, whether it's used with an AIS receiver or transponder. It’s also been designed to be used with other manufacturer's AIS receivers and transponders making it very versatile.

One easy to install junction box - This new splitter provides a convenient and intelligent junction box for VHF, AIS and AM/FM break out points. Using the SP160 allows AIS transponders or AIS receivers to be easily installed with a single coaxial cable run to each device and only one cable to your shared VHF antenna.

Outstanding receive performance - The unique design of the SP160 means it doesn't have the signal loss associated with other AIS splitters ensuring you can achieve full performance from your VHF radio and your Vesper Marine WatchMate or XB-8000 (or other AIS receiver or transponder).

Improves AIS receive range - The SP160 improves AIS receive range by providing amplification to the AIS signal resulting in much higher AIS sensitivity - especially useful for receiving the growing number of 2W Class B AIS transceivers.
