This means: The small side of the antenna points to the direction of the transmitter. Now you know that the transmitter can be situated in both directions of the small side, that is when the Sense- screw is used. In the null- position of the antenna the Sense - screw is touched, and the antenna is turned 90° to the left and to the right. You notice a weaker and a stronger signal.
