text: The wave generated by the driven element (green) propagates in both the forward and reverse directions (as well as other directions, not shown).
text: In the forward direction the net effect is a wave emitted by the director (blue) which is about 110° (180°–70°) retarded with respect to that from the driven element (green), in this particular design.
text: In the reverse direction, on the other hand, the additional delay of the wave from the director (blue) due to the spacing between the two elements (about 35° of phase delay traversed twice) causes it to be about 180° (110° + 2 × 35°) out of phase with the wave from the driven element (green).
