6. MOUNTING OF ODU SUPPORT PLATE AND PARABOLA ON HINGS
ODU support plate is mounted to hings via bolt M6. Parabola is mounted to Hind via 4 bolts M6x16
Antenna assembly
1, To screw ODU support plate to hings (don’t draw up the bolts)
2, To screw parabola to hingspřišroubit (don’t draw up the bolts)
3, Draw up the bolts holding ODU support plate and parabola.
4, ODU is attached to ODU support plate via 4 clips.

7. HING SPRINGS MOUNTING
Before attaching of reflector and ODU is recommended to put spring on Hind. Please, pay the attention of nut
position below:
Hing spring nuts have faced tolls skewed. Skewing has to fit tighly
to inside hing folds.
Correct nut position check before antenna mounting on jib
and springs drawing up.

8. REFLECTOR MOUNTING
10 mm
Reflector is mounted on ODU flange . Bolt heads M6x16are arranged into parabola and and self‐locking nuts
with washer out of parabola.
Head bolt square has to fit in openning in order the parabola is properly drawn up and bolts don’t turn around.
Before bolts inserting, check out whether openings are
down.
9. ANTENNA RADIATOR INSERTING
Antenna radiator is mounted on ODU support plate via bolts M4x10. Pay the attention to drawing up of bolts.
Handle antenna radiator with care , because any damaging has the direct influence to antenna parameters.

10. RADOM MOUNTING
Radom – protects reflector against accumulation of snow, ice and dirt, and have to be mounted on para‐
bola with proper oriented ALCOMA logo. Thus is correctly ensured proper water outlet. Radom is mounted
by bolts ST 4.9x9 with washer. We recommend to draw up all bolts after clamping all bolts into parabola.

11. JIB MOUNTING ON ANTENNA
13 mm
There is necesery to keep uniform drawing up of of spring on jibs!
Jib clear pipe end has to overreach at least 20 mm!

12. ODU DEMOUNTING
8 mm
In case of necessity of service procedure or polarization changing there is necessery to remove ODU by relea‐
sing 4 clips that holds ODU on ODU support plate. During ODU removing is not changed antenna pointing. Nut
wrench is used for bolt grounding.
