What brand/model 12v GPS antenna is being used, reasons?

The ones supplied with Powerflarm core, Cambridge 302, and ClearNav. Later, I
removed the 302 and put in a Butterfly vario, using it's supplied GPS antenna.
Everything seemed to work the same.

The antennas included with glider instruments aren't good to 12v. Give them a try at 9-12v and report how long they last.

I just connect them to the instrument that was in the same box. I was puzzled
about the assumption they were 12 volt antennas; don't have a clue, either.

Eric,

They are not 12V antennas. Most if not all state of the art flight computer GPSs feed the antennas with 3v to 5v.
