I was wondering how this could make sense until:
The result is an antenna that operates at very low frequencies, around 35–36 kHz, while remaining far more compact than the conventional electrical antennas that work at those same frequencies.
They are using a super low frequency.

youd think optic fiber like Ukraine is diing would be viable to some extent.
