The High Gain Antenna is composed of parts 20 (main antenna pole), 21 (dish support and gimbal system), 22 and 23 (dishes) and 24 (feedhorns). Part 21 is covered with aluminium paper and painted in white to mimick the thermal blanket around the real part. The grid covering the dishes is made out of stockings. The direction of the antenna is almost perpendicular to the X axis of the spacecraft to point the Earth during the trans-Earth EVA.
