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

Interestingly we had a near miss lightning event some years ago. An electrical surge came into the boat, a lot through the radar and the aerials. We had two identical backup Furuno digital GPS mounted at the nav station. The aerial for one was mounted outside on the rail, the other under the deck near the nav station. The one fed by the external was cooked, the internal aerial unit was fine.
Another thought: On a previous yacht with much lower freeboard than the Amel we had a GPS aerial mounted internally near the nav station. Offshore in big swells it at times lost satellites as there were hidden behind the swells. (the South Pacific between New Zealand and the Pacific islands can haves BIG swells) By putting the aerial a little higher we overcame the problem. Obviously these satellites must have been near the horizon.
