Can anyone tell me where the actual antennae for the GPS on a SO379 is located? Is it within the chartplotter? I know I often see sailboats with the mushroom GPS antennae attached to the rails or arch, so curious where it is on my vessel. Thanks.

What brand and model of chart plotter do you have? My Raymarine e7 has an internal antenna, but the unit I replaced had a mushroom mounted on the stern rail.

My Simrad on our 379 has the gps in the chart plotter.

It came with the B&G (Simrad) Zeus Touch 7... I should have looked deeper before posting, but did find on the product page that it's an internal GPS, with an external one optional... www.bandg.com/en-GB/Products/Zeus-Touch-7/ (go to Specifications tab) I guess my curiosity now is whether the internal antennae proves too weak for some people, forcing them into an external? Or is it just that some companies don't package the GPS inside.

I haven't had any problems with the internal antenna in my Raymarine e7, but it's located in the cockpit with a clear view of the sky except for the bimini.
If it were mounted below at the nav station, an external antenna might be required.

Hi Tigidal, our 2012 379 has a simrad nss 8, [previous model to yours] in a fiberglass pod on the cockpit table. It has an internal an tenna. I have noticed no significant reception problems in 3 years of use on the British Columbia coast using a navionics gold program.

Thanks for the replies... Just one of the 10,000 questions I have as we launch the 379 for its first season.

I was talking someone at Raymarine and they said that generally there is no problem with GPS reception in plastic boats. Steel boats are obviously a problem and what I did not realise, so are wood.

On my boat the B&G uses it's internal built in antenna and I have an additional "mushroom like" GPS antenna on the port side for the AIS receiver.

Our SO379 is fitted with a Simrad NSS8 chartplotter with Internal GPS and loaded with Navionics charts ... after 3 seasons report no problems with this system to date.
We also have a GPS enabled laptop computer loaded with Meridian Chartware and a Tablet loaded with Navionics as back navigation systems.
If we upgrade this season to the Simrad NAIS- 400 AIS Transceiver we will also fit a extra high speed GPS antenna deck mounted on the port side which feeds into the can bus line thus adding further redundancy.
Hope this helps ...

My 50Ds has a e95 at the nav station and the gps signal was unreliable, so fitted a a75 at helm and connected with ray net cable and sea talk ng, so the e95 is the master with the maps but the gps is from the a75, also have an ais 650 and can use the externally mounted gps from that, but it's supposed to be used for AIS only. Just in case that all fails have open cpn on laptop and raspberry pi displayed on TV. Also have raymarine app on iPad, great for night time use, looking at radar and AIS from your bunk! But not so good in bright sun. I found a centrally mounted display was too far away to see and use especially for radar and AIS. The flush mount mushroom gaps for the AIS is mounted just aft of the port helm seat and is very quick to get a fix and keep it.

Just a general note - on my previous boat I mounted my internal antenna GPS - garmin - in a carbon fibre housing. This seriously impaired reception and I had to add an external mushroom antenna. carbon fibre is a no no for antenna reception.

just as a fyi, if interest in external GPS antenna. My Ray Marine GPS external antenna failed last summer. I replaced it with a Digital Yacht GPS 150 antenna. It was "plug in and play", about 1/3 the cost of a replacement Ray Marine antenna, 50 channel, multi speed and multi GPS system capable (global US, glonass and galileo system once up and running by Europe.) Digital Yacht has a good website for more info. One of my racing Pals updated his boat with a B & G multi function display. The B&G is really an impressive piece of gear, especially when incorporated with on-board wireless connections.

We specified the NAIS-400 when we bought Anwen and mounted the GPS mushroom on the deck near the port helm. There is a smooth flat circle surrounded by the non slip moulding that is just the right size for the GPS antenna.
