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 6-10.
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 (pn 17049) or
even concrete footings for the tripod feet and guy anchors should be
considered.
