<p>An electromagnetic pickup device (64) for receiving electromagnetic signals, transmitting electromagnetic signals, or both. The device (64) comprises an H-field probe (68) having an end (78) the is insertable into the earth for receiving the H-field component of the electromagnetic signal. A plurality of E-field probes (66) are coupled with, and electrically isolated from, the H-field probe (68), and each have an end (76) that is insertable into the earth. The E-field probes (66) receive the E-field component of the electromagnetic signal (62). <IMAGE></p> |
