Hello Arne, Close. Generally it is accepted that pointing the transmitter antenna at the aircraft will create the worst signal reception as seen from the aircraft's receiver.
Due to the human, and the near earth ground plane, the actual area of worst reception (null point - or area of minimum radiation fromn antenna element) is when the antenna is pointed below the aircraft. Where exactly can change based on the height of the transmitter from the ground and the angle. If the transmitter were left standing upright (no human - antenna at 90 degrees to the ground) the null point would be close to the line of sight along the antenna (directly above).
