An AIS receiver or transponder requires a VHF antenna. However, Digital Yacht’s new SPL1500 VHF antenna splitter allows an existing antenna to be used for both the AIS and VHF (DSC). Unlike most simple splitters, the SPL1500 can also be used with a class B AIS transponder system. It also incorporates special circuitry to ensure safe operation of the two transmitting devices.

The unit has three simple connections – one input for the main VHF antenna and then outputs for the AIS receiver/transponder and another for the DSC VHF. It utilises Digital Yacht’s new, patented, ZeroLossTM technology, to ensure the very best possible reception and transmission from all devices. Most importantly it is also fail safe. This means should the unit ever stop working or lose power, it will not affect the main VHF operation. Until now, Digital Yacht, have recommended a dedicated antenna for a receiver or transponder. However, with the new this new ZeroLoss ™ technology, we can now offer a solution that greatly simplifies installation whilst maintaining performance.

The unit is waterproof and matches the aesthetics of the current AIT1500, so can easily be integrated into any vessel. It is suitable for operation on 12V or 24V systems. Three LEDs show the status of the SPL2000. LEDs indicate the correct powering of the unit; and also when the AIS or VHF transmits.
