Figure 8: Protect all antenna connectors from water using self-amalgamating tape.
The complete guys, consisting of 3 wires and 1 collar, incl. accessories, are supplied pre-assembled.
The lower guy ends are 0.3 m longer than theoretically required in order to balance the mast on an
uneven surface. Apart from that, a surface as plain and tight as possible should be selected for the
weather station! Two guy ends have to be equipped with a plain thimble, while the third one gets an
additional spanner, featuring a fine alignment after erection (see Figure 10).
After having defined the exact position of the mast, the mast is erected by two persons. While one
person holds the mast in upright position the second person can determine the precise locations
where the earth nails have to be driven into the soil (see Figure 9 and Figure 13). The nails should
have an angle of about 20
o
with respect to the vertical (Figure 11).
Figure 9: Determine the precise location of the nails using the guys.
The earth nail with additional spanner must be done as last. Before you determine the exact position
of the last earth nail, first set the spanner to maximum range so you have enough room for adjusting
the spanner for levelling the mast precisely (using a water balance). Finally, the base plate of the mast
can be fixed using 4 small nails and the mast can be grounded via the grounding rod.
