Raymarine AIS Splitter 100 powered aerial splitter allowing both an AIS transponder and a conventional VHF radio to share the same transmitting and receiving aerial. This will allow you to use your masthead aerial for both instruments with only marginal transmission and receiving losses that are arguably outweighed by using the highest point on your boat and thereby achieving maximum range.
The splitter has been used, but is in excellent condition and was in good working order when last used shortly before it was disconnected.
It comes with both a power cable and a connection cable to your nearby mounted AIS and a power supply, and a fuse and fuse holder.
