CM106B Tripod 

12 

6.1.4  Staking the Tripod Feet 

Six stakes are provided for securing the tripod feet to the ground. Drive two 

stakes through holes in each foot at an angle as shown in FIGURE 

6-7

. 

Stakes may not be adequate depending on soil structure, maximum wind 

speeds experienced at the site, mast height, or wind load from the 

instrumentation. For questionable situations, additional stakes or even concrete 

footings for the tripod feet and guy anchors should be considered. 

Keep the bottom of the tripod legs free of soil, ice, and debris 

to prevent trapping any moisture inside or around the legs.
