Advantage of Class B+ AIS on a sailboat?

Exactly, the difference is huge.







So what was your SWR on channel 16? If it was 2:1 or worse, your installation isn’t okay and is causing interference on other systems aboard or at other boats. The cases where channel 16 traffic was problematic because of AIS interference are documented.


Last time I did a radio check with the vhf and old antenna I got out to 27 miles. The antenna wire and connectors are good. Don’t know what the new antenna vswr on vhf is though. I just put it up yesterday.

If my AIS can’t reach satellites I see that as a good thing

Ha! With our Vesper we can disable transmissions completely

The reason for being seen by AIS satellites is during emergencies, when SAR teams try to find you.
