ATU can be divided into 3 parts, when necessary.
Radome top
1) Put Antenna Unit on a workbench
Loosen the 12, M10 bolts around the
radome and remove the radome top. M10
will remains on the radome bottom.
Do not lift up the radome top carelessly,
because flange inside radome top may hit
the tip part of the antenna which is very
fragile. Once lift up the radome top high
enough to check the position of antenna and
rotate the antenna elevation upward by
holding the counter weight arm by hand if it
is facing horizontally.
Use some pillows or lumber under the
bottom edge of the radome top that will
make easier to put hands under radome
when lifting up. Do not place directly on the
floor or it will be hard to lift up without space
under the radome.
