Re: [Amel Yacht Owners] GPS Antenna below deck?

Ryan Meador

Fiberglass is mostly transparent to radio waves, so it should have only a tiny impact on signal strength.  But GPS (and any satellite) signals are already very weak, so it might be enough to cause you to "see" fewer satellites than you would with a clear view of the sky.  It shouldn't cause any position error.  Take care that your sensor isn't behind any metal or wood, or even some kinds of paint, which can block signals.

In tracing down the wiring on the boat I've found another GPS antenna!

It provides position data to the ACR Nauticast B AIS.  It was installed in the ceiling space above the midship cabin (just fwd of the aft cabin), attached with silicone to the overhead, and it had fallen over and must have been rolling around up there in a heavy sea.

We've always had good results from the Nauticast so I'm likely to leave it there, unless there's a good reason not to?   Of course I'll improve the mounting situation.

I'd appreciate your thoughts.
