are secured with a lanyard.
3. To attach the lower mast section, hold the mast upright and align the hole in the bottom of
the mast with the holes in the tripod base. Insert the pin through the holes, and rotate the
wire retainer over the end of the pin as shown in the following figure.
4. Secure the mast in the upright position by installing the locking bracket:
a. Insert the top of the bracket into the notches in the tripod base, and using both
thumbs, press the bracket into the body of the base until the lower tabs lock into
position.
b. Install the pin.
5. Plumb the tripod by adjusting the northeast and south facing legs. With a level on the east
side of the mast, adjust the northeast leg for plumb. With the level on the south side of the
mast, adjust the south leg for plumb.
C.3 Staking 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 the following image.
Figure C-2. Staking the tripod feet
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.
