Ham Radio-Ground Spike Antenna. Using the earth to receive LF and VLF. Post #1468.

Here's an interesting, unconventional antenna that could open an entire new world of radio listening.  In this video from Kevin Loughin (KB9RLW), we learn how to use what Kevin calls a "Ground Spike Antenna" to tap directly into the earth for LF and VLF signals.  Now that radio amateurs in the U.S. and elsewhere are able to transmit in the 630 and 2200 meter bands, antennas such as the "Ground Spike" could help you explore the largely untapped universe below the standard AM broadcast band.  Kevin does an excellent job of showing just how easy it is to tap LF and VLF signals by using the earth as a key antenna element.  Build one of these antennas and prepare for some unusual listening, courtesy of the earth itself.
