Placement Guidelines – Ground Unit
The following describes the mandatory requirements and the best practices for
optional placement of the Ground Unit and its antennas.
• Place the Ground Unit as High as Possible: Place the Ground Unit on a tripod,
pole or table so that it is as high as can be. A height of 2 meters is optimal.
• Place the Ground Unit Antennas Facing the Air Unit: Place the Ground Unit so
that its antennas are facing upwards in the general direction in which the aircraft
will be flying. The five Ground Unit antennas can be placed as if the Ground Unit
and its antennas are an open hand with the palm facing the aircraft, as shown
below:

• Avoid Interference: Place the Ground Unit cable antennas as far away as possible
from other transceiver devices, especially from a transmitter in the 5 GHz band.
