On the ODU, the two flange styles are:
• UDR. 6-hole or 8-hole (6/8 bolt holes depending on frequency range/
waveguide type), flush-face flange with threaded, blind holes.
• UBR. 4-hole flush-face flange with threaded, blind holes.
The corresponding mating flange styles are:
• PDR. 6-hole or 8-hole flange with gasket groove and clear holes.
• PBR. 4-hole flange with a gasket groove and clear holes.
All fastening hardware is metric.

Remote-Mount Installation Procedure
This topic describes the installation of a remote mount, the attachment of the
ODU to the mount, and the installation of the flexible waveguide.
Related procedures are:
• Installing the ODU Lightning Surge Suppressor; refer to Installing Lightning
Surge Suppressors on page 2-23.
• Grounding an ODU; refer to Grounding the ODU on page 2-13
• Installing the ODU cable and connectors; refer to Installing ODU Cables and
Connectors on page 2-19
Installing the Remote Mount
The remote mount attaches to a standard 112 mm (4”) pipe mount using two
saddle clamps. It can be installed either way up, and with a left or a right offset.
Firmly fasten the clamp nuts.
