Now
enter
into
the

“180.0”
into
the

The
feed
horn
should
rotate
90.0
degrees
clockwise
(when
viewed
from
the
front
of
the
reflector)
so
that
the
alignment
marks
of
the
phase
card
in
the
feed
horn
are
aligned
diagonally,
in
a
north/west
position
(as
shown

If
the
system
completes
all
of
the
above
tests
than
the
polang
assembly
is
operating
correctly.
Set
the
antenna
back
into
automatic
polang
mode
by
entering
into
the
“Reflector”
screen
under
the
configuration
options
and
set
the
polang
drive
mode
to
“Automatic”
and
click
the
save
button.
The
antenna
will
now
automatically
calculate
the
correct
reception
position
for
the
feed
based
on
the
vessels
GPS
location
and
the
look
angle
to
the
desired
satellite.
Should
the
feed
assembly
drive,
but
not
target
the
correct
position
this
is
an
indication
that
the
pol
pot
is
not
calculating
the
feedback
correctly
and
its
resistance
should
be
verified
as
per
section
