Plan where to position the components
12
Step 3. Plan where to position the
components
Determine where to position the QGFSP components and decide
which mount is best suited to the current work site. Be certain that
the RAU antenna has a clear view of the sky, that you have provided
adequate grounding, and that you have the correct number and
lengths of cable.
•
Two recommended mounting configurations are shown in Figure
2 and Figure 3. A poor choice for mounting is shown in Figure 4.
Note that in the figure, reception is blocked both by building and
by tree.
•
Use the sighting tool to help determine whether there are
obstructions to satellite reception. (See page 13 for instructions.)
•
Plan how to ground the QGFSP. If there is an existing lightning
protection system, see Figure 27 on page 38 for how to install the
QGFSP.
•
Position the junction box on the outside of the building, near
where the inner telco wires meet the outside, and close to the
grounding rod.
•
Be certain that cable lengths will be adequate. Recommendations
are on page 14.
