#Schematic vlf receiver driver

There is no need to match this transmission line to the recorder driver because the signal has already been amplified 900 X. After the signal is amplified 900 times it is sent over a transmission line consisting of ordinary 4-wire telephone wire to a recorder driver. The receiver is built right on the loop antenna so there is no need for a transmission line between the antenna and the receiver. I meet the second requirement by eliminating the transmission line altogether. I meet the first requirements by building a hexagonal loop antenna that measures 1.5 meters (59 inches) across the diagonals and winding it with 24 turns of # 14 stranded copper wire. The design is based on the principle known to all amateur radio operators that the most important part of a transmitting or receiving system is a good antenna and a well matched transmission line. The loop antenna that goes with it will take another day to build from stuff you can buy at Home Depot or a similar store. You can build it in one afternoon from about $10 worth of Radio Shack parts.
