    Features:

    • The SI-TEX MDA-3 AIS Antenna Splitter provides signal gain, improving AIS reception and range.
    • The SI-TEX Antenna Splitter is an Intelligent device that allows both the VHF Radio and any AIS Device connected to receive signals simultaneously.
    • Allows the use of the primary ships VHF antenna for both VHF radio and the AIS transceiver. Eliminates the need for 2nd Ant.
    • When either the AIS transceiver or VHF radio transmits, the AIS antenna splitter automatically senses the transmission and routes the signal to the antenna.
    • If the VHF radio is transmitting when the AIS transceiver wants to transmit the SI-TEX AIS antenna splitter will give priority to the VHF radio and allow the AIS to transmit as soon as the VHF radio transmission ends.
    • The Antenna Splitter has a fail-safe mode that allows the VHF radio to operate normally in case of a power failure.
