411 14Engineering Preparations and Unpacking Check1-Checking
installation conditions:- a-position of dish on tower(height and
azimuth). b- IF cables route on tower and the roxtec and inside
indoor room. c- Position of IDU inside indoor room(if rack exist or
we will install new rack). d-Check power source. e-Check earth
system. f-Air conditions quality. g-Equipment secure.
Engineering Preparations and Unpacking Check 2-Unpacking the
equipments and check if they match the design or not Before
starting work we have to check Delivery carefully and ensure that
all equipments matching the link budget, we should check the
following: a-The Antenna (Two Antennas must have the same
band).b-Bracket and site arm (check compatibility with Dish
diameter)c-ODU (Checking Band and Sub-Band and ensure that link
budget frequency within ODU range).d-The Indoor equipment (Rack,
RTN, RTN Boards, Rectifier, Batteries)e-RF Cable and its
Accessories.

Caution:-Outdoor installation of microwave equipment involves
working at heights. Ensure the safety of the team.
Installing The Antenna on the tower on the required Height as
mentioned in the link budget .We have to choose the suitable
position carefully especially for big dishes (1.2m or bigger) and
ensure that the dish support with right angleCheck the azimuth of
the antenna using compass or GPS.Also verify polarization and type
of the antenna as mentioned in the link budget.
Hoisting the antenna
Caution:-Ensure no people below the iron tower when installing
and commissioning outdoor equipment.For a large size antenna ,two
pulling ropes are required. And bound to different points of the
hoisting rope to prevent the antenna from rotating
The hoisting rope is used to hoist the antenna ,and The pulling
rope is used to pull the antenna to prevent the antenna from
colliding with the iron tower.
Fix the antenna to the pole. during the fixing ,do not remove
the hoisting rope from the antennaNote:- Antennas , hybrid couplers
, and ODUs must be hoisted separately. hybrid couplers , and ODUs
must be separately installed after antenna installation.
