One of the great difficulties associated with the use of ELF for communication purposes, is the problem of generating a useful signal. The physical size of an antenna that can produce a useable signal with reasonable efficiency is inversely proportional to the frequency.
The Wisconsin antenna consists of two lines, each about 14 miles long. The Michigan antenna uses three lines, two about 14 miles long and one roughly 28 miles long... A 165-mile underground cable connects the two sites which have a typical operating frequency of 76 Hz. Due to its low frequency, the antenna systems is huge: a directly-generated electromagnetic wave at 76 Hz has a wavelength of 2,452 miles.

You really dont want Swedes outside of Sweden, we will destroy anyones reality. Swedish culture is almost 200.000 years old, yours is 400 years.
We make fun of you sometimes, cause you are children who knows very little.
