Foundation
Soil and Frost Conditions
When designing the foundation, a local construction company must be
consulted to find out about the soil and frost conditions in your area.
When the soil is frost-susceptible, make sure to always use the proper
insulation.
Orientation of the Mast
Refer to Figure 36 on page 52 and Figure 37 on page 53 for the
orientation of the mast. The concrete pads for guy wires have to be
placed so that the pole mast can be tilted west (east in the southern
hemisphere) by releasing only the guy wire 1.
To ease the orientation of the mast, the two-headed arrow is cut on the
orientation plate. "N" should face north and "S" should face south to
ensure the aiming of the weather station devices to the correct
position.
