I know a few people who are experimenting with it, but repeaters are few

but it starts to get expensive to update position more frequently than
every 15 minutes or so:

Every 15 minutes would still be useful. That would be, at worst, about a
40 mile diameter circle of "potential location" around the last
transmission of a flying glider. It might still transmit after a crash,
too. What kind of antenna does it need? Is that the antenna on the top
of the unit in the picture?

I believe it uses a separate patch antenna, similar in size to those
used by GPS receivers...
