Installation Check
Items to be checked for the antenna, Hybrid Coupler, and ODU
Serial No. Checking Requirement
1 The installation location and direction of the antenna should conform to the information in
the engineering design document.
2 The antenna should be correctly installed (the side of the antenna with a wider shield
should face upwards and that with a narrower shield should face downwards).
3 The logos of the antenna and comber should face upwards.
4 The antenna support should be correctly installed on the pole. The connection should
withstand the weight and the force of the wind.
5 The four screws of the ODU should tightly engage with the antenna or the hybrid coupler.
6 The four screws of the hybrid coupler should tightly engage with the antenna or the hybrid
coupler.
7 The antenna, hybrid coupler, and ODU should be in the protection range of the lightning rod
(the protection angle of the lightning rod should be less than 45 degrees. In mountainous
and thunder prone areas, the angle should be less than 30 degrees).
Items to be checked for Separate Mounting Components
Serial No. Checking Requirement
1 The installation location and direction of the ODU separate mounting bracket should
conform to the information in the engineering design document.
2 The ODU separate mounting bracket should be correctly installed on the pole. The
connection should withstand the weight and the force of the wind.
3 The four screws of the flexible waveguide installed in separate mode hold the antenna feed
boom tightly.
4 The flange of the flexible waveguide should be firmly and correctly connected to the
antenna interface of the ODU and antenna feed boom.
5 The bending radius and twist degree of the flexible waveguide is within the allowed range.
6 The separate mounting components should be in the protection range of the lightning rod
(the protection angle of the lightning rod should be less than 45 degrees. In mountainous
and thunder prone areas, the angle should be less than 30 degrees).
