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

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

Features:

• 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
