Hi am thinking of installing a new AIS on my Moody the above Raymarine 700 if I'm correct is stating that

"Built-in antenna splitter simplifies installation with existing VHF radio antenna"

Does this mean you can use you're existing vhf antenna to send out the AIS transponder signal
I understood that you need a dedicated AIS antenna for this? unfortunately cannot email Raymarine direct

Thanks
Maurice
 
Yes, the splitter allows you to share the same masthead VHF aerial between the AIS and the voice VHF. This is newer than my version of the Raymarine AIS, but been using the splitter approach for 8 seasons so far without issue.
 
AIS700 is great. I installed mine 2 seasons ago running it, as advertised, through the ordinary VHF aerial. No problems with range.

Nothing wrong with the 700-AIS, apart from its price. It's made by a company called SRT, the parent company of Em-Trak, but typically cost about £250 more then the Em-Trak B953, which has all of the same features as the 700AIS.

Did you install the new GNSS GPS or can you use your old GPS? this would make installation even easier
Thanks

Since my AIS700 was part of a suite of Raymarine systems, yes, I did install a Raymarine GNSS receiver. I mounted it on the top surface of a cabinet next to the chart table. I.e an interior installation. It’s never given me any problems.

The AIS must have a dedicated GPS and this is what the AIS will use, regardless of any other GPS sources on the network. This is a requirement for transmitting AIS.

No need for additional GPS sources, the AIS will output data over NMEA 2000, STNG (with an adapter cable) or devices on an NMEA 0183 bus.


The Em-Trak AIS has built in GPS and this is what the AIS will use, regardless of any other GPS sources on the network.

Oops, I meant to say antenna. The unit has a built-in receiver, but it needs the dedicated GNSS antenna - as per the install manual.
