Vesper Marine SP160 AIS VHF Antenna Splitter
Designed to work with any Class B AIS receiver or transponder with unique integration features for the AIS WatchMate Transponder. To simplify installation you can share an existing VHF antenna by using this splitter. The unit removes the need for a separate VHF antenna for an AIS receiver or transponder and allows a single antenna to be shared with a VHF radio. This is an excellent solution when it is difficult to install an additional antenna or you wish to share an existing VHF antenna and maximize your AIS range. This Vesper Marine splitter is specifically designed for use with both AIS receivers and transponders. All other AIS splitters introduce significant signal 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 useful as more and more lower power Class B AIS transponders and SART's are installed. In addition to the amplification provided by this splitter, when used with your existing antenna you can optimize the range of your AIS transponder because the antenna is also mounted as high as possible. | Frequency Range | 156MHz to 163MHz | | Operating temperature | -25°C to +55°C (-13°F to 131°F) | | Environmental | Watertight (USCG CFR-46, IPx7) | | Power Supply | 12 - 24 VDC, <0.8W nominal | | Overall Size (incl connectors) | 135mm Long x 107 Wide x 56 Deep (5 5/16” x 4 1/4“ x 2 1/4”) | | Maximum VHF power | 25W | | Maximum AIS power | 12.5W | | VHF & AIS Connectors | SO-239 (UHF) | | AM / FM Connector | BNC, optional cable available BNC to Motorola plug | | Insertion Loss | VHF RX 1.5dB / VHF TX 1dB / AIS TX 1dB | | AIS Receive Gain | 12dB | | AIS Sensitivity | -119 dBm, 6dB improvement |
Note: The splitter includes one 2m (6.5ft) long patch cable to go between the splitter and your VHF radio. You will need an additional appropriate length 50 ohm cable with standard PL259 plugs to go between the splitter and your AIS transponder or receiver. This should be ordered separately based on the required length. See the related products list for popular options.
