SI-TEX Metadata VHF/AIS Antenna Splitter - MDA-3

Item # 883293


The SI-TEX Antenna Splitter is an Intelligent device that allows both a VHF Radio and any AIS device connected to receive signals simultaneously.


  • Provides signal gain, improving AIS reception and range
  • Allows the use of the primary ships VHF antenna for both VHF radio and the AIS transceiver - eliminates the need for 2nd antenna
  • When either the AIS transceiver or VHF radio transmits, the AIS antenna splitter automatically senses the transmission and routes the signal to the antenna
  • Fail-safe mode that allows the VHF radio to operate normally in case of a power failure
  • Low power consumption
  • Works with both 12/24V
  • Quality construction made specifically for marine use
  • Includes LED indicators to provide information regarding the status of the AIS antenna splitter
    • Power - Indicator is illuminated while the unit is powered
    • TX AIS - Indicator flashes to indicate AIS transmissions
    • TX VHF - Indicator flashes to indicate VHF radio transmissions
