That translates to "it disconnects the AIS receiver when you key the mike on
the VHF, otherwise the AIS receiver would be very upset at the amount of power
it was fed".

Smart Radio (Milltech Marine) offers an active splitter so you can use the
same antenna for both vhf and ais.
However, it seems expensive. So what is an active splitter? (Does it turn
flips to or just splits?) Why so expensive? Is there a substitute?
Thanks

Probubly an RF Activated Antenna Switch with internal 1/4 Wave Stub
Grounding on both radio ports, if it is designed for full AIS
Transponder operation. Seems kind of a stupid idea, if it costs more
than a second antenna would cost. But hey, what ever blows youe skirt
up......
