Well, with the Digital Yacht's vhf splitter, you can in fact have 1
antenna and utilize the vhf and AIS. The splitter has
some smarts to manage it all. I agree you can't just simply wire the
two to one antenna. Our installation worked
just fine, we were able to talk to the cargo ship which was on a
collision course with us...and, yes, he did see our AIS
signal. So, fairly positive confirmation that the setup worked as intended.

A transponder (emitter and receiver) requires it's own antenna, which
mean you cannot use the same as the VHF. This mean a choice to make
because two antenna emitting on VHF channels should be separated by at
least 3 feet, and no, the top of the mast is not that large. For ocean
traveling, I decided to use the top of the mast antenna for the AIS.
This meant increasing by far the range of the AIS. I once tracked a
cargo ship as far as 82 miles away. Le VHF radio antenna was installed
on the pulpit. Out on the ocean, the VHF is useless, unless there is a
ship nearby. If you're not within 100 miles of a nearby shore, the
things remains totally silent. Actually, I remember listenings four
time the weather forecast just to hear the woman's voice who was
delivering it. But that was after having spent 17 days alone. The AIS
was one of the best security item I had on the boat because it is an
active system. It tells the others you are there.
Negative point: I had an ACR, which required to be sent back to the
company for a reset if you want to change boat or sell it. I was asked
$125 for the reset plus transport between Canada and Florida. Ouch.

There are several inexpensive AIS transponders with NMEA 2000 and
built in gps antenna. The Vesper also has wireless. Ignore the
first one - NMEA 183 only.
Does anyone have any experience/recommendations:

Any idea how long it takes the FCC to issue a Ship's Station License?
I applied online.
