Many AIS splitters introduce significant signal loss, some claim 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 powered AIS SART and MOB devices.
