Well, there's a now unused original circuit breaker on the DC panel for "SatNav". But I've been searching for images
of various sat nav marine
antennas, and cannot find anything close to this. I know it's obsolete, and I'm going to take it down when I'm up there. Was mostly curious, as I've been going to sea since my summer jobs running gravity meters and such in the mid 60's working offshore
C, and have at least some experience with just about everything since, and I don't recognize it. I was thinking that if I knew what it was I could offer it for sale
in case there's somebody somewhere that wants one of these. Pretty safe bet it's rare these days. Otherwise I'll just chipcan it.
