Installing the Flexible Waveguide
Waterproof the connectors between the flexible waveguide and the ODU/hybrid coupler/antenna by referring to page 48.
The flexible waveguide are available in multiple types. This procedure for installing the flexible waveguide is provided for reference
only. In actual installation, follow the instructions delivered with the flexible waveguide.
The flexible waveguide can be bent only within its maximum twist angle and at the larger area side. The E-bend radius and H-bend
radius cannot be smaller than the minimum bending radius.
To ensure that the flexible waveguide is installed securely and steadily, it is recommended that three sets of fixture be installed for
each flexible waveguide. Fix the flexible waveguide at the two ends and in the middle with the fixtures. For detailed installation
position and methods, see instructions delivered with the flexible waveguide.
Fix one end of the flexible waveguide to the flange interface of the ODU/hybrid coupler and the other end to the
flange interface of the antenna. The direction of the flexible waveguide should be consistent with that of the
ODU/hybrid coupler/antenna. Use the fixture to fix the flexible waveguide.
The direction of waveguide cavity of the ODU
must be the same as that of the waveguide
cavity of the flexible waveguide.
