Splitter Function
The easyTRX2-IS has an integrated antenna splitter. By means of this
splitter with built in RF signal amplifier, physical losses are eliminated.
The splitter is checking whether there is transmit power from the VHF
radio or the Class B AIS transceiver to the antenna. In case of this, the
splitter disconnects very fast the other connected units (<1ms). In the
standard reception mode the units are all connected to the same anten-
na. A very fast disconnection is necessary because the easyTRX2-IS does
transmit its signal with 2W power in a very short time. Therefore the
used splitter has to disconnect the other units even faster than the de-
vice starts transmitting its message.
Caution!
It is not allowed to plug a VHF radio to the antenna port of the ea-
syTRX2-IS. Demolition of the internal AIS receiver might be possible.
