The important
thing
in horizontal
mast
leveling
is positioning
of the foot
on the
mounting
surface.
This is due to the one adjustment
of the foot. When

surface,
orient the adj u stment in the direction
that h as the most angle
to it.
For
example,
if you are mounting
the foot on a roof,
orient
the foot
so the
adjustment
is parallel
to the pitch of the roof (see figure
27).
Figure 27, Orient the Mounting Foot on a Horizontal
