While true, it is still pretty damn hard to transmit 77.5-100kHz
very far without a physically significant antenna, and you can
forget everything about any directivity of any transmitting antenna
you might use.

Furthermore, you can literally pinpoint any VLF transmitter
with just a ferrite rod, a diode and a crystal ear-piece.
You do not even need a tuned filter when you get close enough.

KiloHertz are not perfect, far from, but they are /so/ much more
resilient than GigaHertz.
