Antenna
Alignment
•
An
audible
buzzer
is
used
on
both
the
Master
ODU
and
the
Slave
ODU.
If
the
external
antenna
is
positioned
so
far
away
from
the
unit
so
as
to
make
the
buzzer
inaudible,
you
may
need
to
use
two
people
to
perform
antenna
alignment.
•
Antenna
alignment
is
carried
out
in
three
stages:
•
Master
ODU
gross
alignment
•
Slave
ODU
fine
alignment
•
Master
ODU

Procedure
1.
Ensure
that
power
is
connected
to
all
radio
units.
2. If
you
are
working
with
an
external
antenna,
connect
the
vertical
polarization
connector
of
the
antenna
to
the
ANT
1
connector
of
the
radio
unit,
and
the
horizontal
polarization
connector
of
the
antenna
to
the
ANT
2
connector
of
the
radio
unit.
3. Ensure
that
the
buzzer
on
both
radio
units
is
configured
to
Auto
).
An
unaligned
ODU
starts
beeping
20
seconds
after
power
up,
and
continues
beeping
until
it
is
aligned.
There
is
no
particular
reason
to
use
ANT
1
and
ANT
2
in
that
order:
They
just
have
to
be
the
same
for
each
ODU
in
the
sector.
Further,
adopting
a
convention
like
“ANT
1
is
always
vertical”
avoids
mistakes
across
a
large
sector.
