Re: Can AIS Share VHF Antenna with Existing VHF Radio ?

I agree with Marc in that it is simpler and more reliable to keep the VHF and AIS transceiver antennas separate.

Also, some AIS transceivers require a dedicated AIS antenna for the transmit function to work. My Furuno FA150 does but many transceivers do not.

Same thing if you inherit a VHF with the MMSI programmed in, you can pay to have it changed, or you can use it illegally, and feel like a CRIMINAL, but it works. My old VHF was like that and I used to DSC other boats to arrange drinking appointments instead of using the boat name on the radio so crooks can tell who if off their boats... But every time I did I shivered in my shoes worrying the International Sea Police would pop out of the anchorage like a Cocaine addicted Mermaid and arrest my finger!



But didnt someone Google how to change the MMSI? It's a series of button pushes as you turn the unit on. Google it and see if you can save the $40

As a practical point though, wouldn't it suck if you hit the Red button on that VHF and the cg passed you by..."nope, that's not him, it's a green power boat, not a white sailboat." ;-)

Re: Can AIS Share VHF Antenna with Existing VHF Radio ?

I think I got to the answer about using the same antenna for an AIS and the VHF. There's another post in this thread about Vesper Marine, a company in New Zealand, that manufactures an active splitter specifically for this application. With the correct splitter you can run them both throught the same antenna. here's where I ordered mine: Vesper Marine: WatchMate AIS Transponders - Dedicated Marine Collision Warning System, they run about $300 with shipping.
