In general, there must be at least 150 m (492 ft) of open area to all directions from the mast.
The minimum distance between the mast and an obstacle is 10 times the height of the
obstacle.

Placing Antennas
When using a satellite transmitter, find a suitable site for the antenna. There must be a clear
line of sight from the antenna to the satellite. This is particularly important for systems
where the satellite is in a
fixed direction. After aiming the antenna, sight along it and make
sure you are looking at the sky. If there are any obstacles in the way, it is unlikely that the
satellite receives a reliable signal.
To ensure correct GPS readings, position the GPS antenna so that it has the clearest possible
view of the sky and horizon in all directions. Avoid sources of electromagnetic interference
such as radar equipment, VHF radio antennas, or generator and engine components.
3.3.3
Placing Sensors
Allow sucient clearance for all the sensors, especially for the wind sensors, and the
enclosure. Do not place the mast next to a building or any other object that may
aect the
airflow.
To ensure correct measurements, avoid the following installation sites:
• Rooftops
• Sides of buildings
• Shaded areas
