11.14 Setting the polarization on the Jupiter Transceiver.
Setting
the
required
polarization
on
the
Jupiter
transceiver
is
fairly
straight
forward,
when
the
unit
is
received
new
it
will
be
set
in
RHCP
so
if
this
is
correct
for
the
beam
you
are
working
in
you
only
need
to
double
check
this
is
correct.
If
you
are
working
in
a
beam
which
is
LHCP
then
the
waveguide
will
need
to
be
adjusted,
to
accomplish
this
complete
the
following
steps.
1.
Firstly
look
at
the
neck
of
the
feed
horn
assembly
where
it
meets
the
main
body
of
the
transceiver
and
identify
a).
The
arrow
on
the
neck
of
the
wave
guide.
b).
The
L
and
R
markings
on
the
main
body.
2.
As
can
be
seen
in
picture
one
above
the
arrow
on
the
waveguide
is
pointing
at
the
R
mark
so
this
is
set
to
RHCP.
To
change
this
to
LHCP
remove
the
four
Allen
studs
seen
above
and
rotate
the
waveguide
anti
‐
clockwise
through
90°
so
the
arrow
points
to
the
L
symbol
(See
below)
ensure
the
sealing
washer
remains
in
place
and
replace
and
fully
tighten
the
four
Allen
stubs,
the
unit
it
now
set
for
LHCP.
