ZEVS (transmitter)

ZEVS is a VLF transmitter of the Russian Navy near Murmansk to alert deeply submerged submarines.

ZEVS achieved since he works on an extremely low frequency of 82 Hertz, although extremely low signal data rates, but with around 3700 km wavelength signals penetrate its deepest possible - up to 300 m - in water. Submarines dive to this depth to opposite Enlightenment " hide" by various methods.

As a transmitting antenna ZEVS uses a Bodendipol, which should be about 106 kilometers long.
