Tilt Direction of Mast
Also note the tilting direction of the mast. When installed in the northern
hemisphere, the mast tilts to the west. There should be a clear area up to
9 m on the west side of the mast. The area should be free of obstacles
preventing the mast from being erected and tilted.
Soil Evaluation for Mast
Always evaluate the soil to determine the appropriate type of the
foundation required. When designing the foundation, the local
construction companies 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 proper insulation.
CAUTION
For the mast base installation, the soil bearing capacity has to exceed
45 kPa (940 pounds-force/sq. foot).
