I just don't see how they will fit a good enough antenna. I highly doubt this will happen.

Maybe it uses an external antenna that is plugged in the headphone jack...

  Like one of these Breitling emergency watches where you pull out a long cord out of the watch and then it sends an SOS signal. Except that with the watch the antenna is single use only to prevent abuse.

    oooo. TIL! The official webpage with absolutely no interesting information: https://www.breitling.com/us-en/emergency/ https://www.breitling.com/us-en/emergency/ There are a few blurry fractions of a second of the antenna being deployed here: https://www.youtube.com/watch?v=cJvyZNHnMGE https://www.youtube.com/watch?v=cJvyZNHnMGE What it sounds like over a radio: https://www.youtube.com/watch?v=KlC5frFhjqs https://www.youtube.com/watch?v=KlC5frFhjqs It comes with a tester (basically a radio with no tuning knob): https://www.youtube.com/watch?v=L3R7lhLqVo8 https://www.youtube.com/watch?v=L3R7lhLqVo8 Edit: I found some more footage of it being used in this highly dramatic, uh, presentation: https://www.youtube.com/watch?v=v2y-TQSL6XE https://www.youtube.com/watch?v=v2y-TQSL6XE

      It was actually used on Top Gear, because of licencing issues the scene is very difficult to find but someone recorded it: https://youtu.be/qHRzUTyi1GE https://youtu.be/qHRzUTyi1GE

        Oh, nice! They appear to have reused that footage in another episode: https://www.youtube.com/watch?v=kgRom5gINtI https://www.youtube.com/watch?v=kgRom5gINtI

Communicating 100km up is far far easier than communicating 100km sideways. Much less air to go through, and less obstructions. A few space startups out there have missions in the sky right now able to do this. The trick is to but high gain on the satellite side to compensate and phased array communications has been coming a long way to really target the power into a directed path than just beaconing.

  > Communicating 100km up is far far easier than communicating 100km sideways Yes, and no. it depends on the frequency. However I don't want to put a phased array shitting out 4-15 watts of power at 1.6gigs near my head. I doubt it'll pass the emissions certification either.
