Providing 2 antennas for a device that has 2 antenna outputs isn’t feature creep.
Absolutely. This is not in question.
That’s… because it is
I highly doubt it, considering one is a coil coil with many turns of copper wire and the other is a planar antenna with 2 turns, that orient their respective EM fields 90 degrees to one another.
That’s true: the ideal combo for us implantees would be 2 coils. But that is definitely harder to design, and more expensive to make.
Look, I ain’t bitching. Tom’s work is top-notch, and if he hadn’t picked up the ball, nobody would have gotten any LF coil at all. No question.
But seriously, if you go to all the trouble of designing a PCB (and a curvy PCB at that) with a complex coil and transparent cover assembly on top of it, it literally costs peanuts to make that PCB square, add a couple traces around the perimeter, and a cap. You know, as a fallback that’s better than nothing, and no worse than the stock antenna for HF.
I’m guessing Tom was focused on the LF design and didn’t think of that. And again, I’m not criticizing. All I’m saying is, it was doable, and not terribly challenging technically or financially.
