Marine GPS Antenna Aerial Replacement for Garmin GPSMAP GDU GNC NavTalk Pilot StreetPilot AIS Boat Ship Navigation Receiver Fishfinder Sounder+26ft Cable TNC Connector+BNC Adapter+Mount Base

This is a powered antenna using 3-5 vdc. It works for a number of Garmins as listed, I found it works well for the larger A series Raymarine MFDs which have a coaxial socket for the GPS antenna. It may also work on other Raymarines with the coax socket. Raymarine sells the GA200 for about $200. Save your money this works

Worked for my Raymarine AIS transmitter.

Mounted it on the boat and connected it and the Garmin GPSMap 215 had no problems connecting again. Unit has been down for a while, thought it was bad. Tried this antenna and it's back in working shape again!

I was looking for replacement GPS antenna for Garmin system and this has worked well to replace the original antenna. Definitely solved the problem.

Lo mejor que pude comprar muy buena calidad.

This antenna works better than the one that came on our boat. It was easy to install. I love the long cable that came with it. It gives me piece of mind when out in the ocean. It is sturdy and durable and weatherproof. The price is great.

Just what I needed. This is not an active antenna but works fine. It solved my GPS receiving issue.

This fit right in where the old one used to be. The old one was damaged during storms and now I can feel more confident going out with a good reliable antenna.The cable was more then long enough, the main body fit and secured right into place and the cable run, although a bit of a pain, was as easy as you can expect with this kind of repair.
