Fig. 273, advance in the general direction E, oscillating cur-rents will be induced in the loop C, D, but none in loop A, B. To obtain the maximuminduction from these oscillations, the exploring coil must, in. this case, lie parallel to thegoniometer excitation winding connected to the terminals of the loop C, D. Again, if the waves advance in the direction E-1, the induction on the loop A, B is maxi-mum and on C, D nil. Hence, the exploring coil must now lie parallel to the goniometerwinding connected to the loop A, B to receive the maximum induction, and the pointer willlie along the direction E-\. If the waves advance in the direction E-2, both loops are acted upon simultaneously and. <^ mm Lz Fig. 274—Receiver ConnectedAerial. to a Single Loop DIRECTION FINDER OR WIRELESS COMPASS. 259
