...especially at night, if any entity is still using the LW band. Wiki
says, "*The frequency for longwave range from 30KHz to 279 KHz , covering a
median wavelength of 150 meters.*" That's really low frequency.
   The antenna in one's mobile phone is only a few millimeters long, or if
a tuned dipole, 3"-6" depending upon the mobile phone band being used.
Broadcast FM radio dipole antennas tune at about 4 feet long. We've all
seen those kinds of antennas in some cars' windshield glass. A dipole
antenna for 30KHz, the very bottom of the LW band, is 15,600 feet long!
