Installing mast mounts 5–3
RT installation
Site preparation personnel specify the ODU location as part of
preparing the RT rooftop drawing.
1. Use the RT rooftop drawing to determine where to install
the mount (at the ODU location) and locate the IFL entry
point.
2. Make sure the roof penetration or entry point for the IFL is
suitable.
Important: The location(s) used for ODU installation must meet
the requirements listed in the Hub and Remote Terminal Site
Preparation Guide. Key considerations include:
• Line of sight
• Distance from HT
• IFL entry location
• Sources of interference
• Safety
• Ground point location
• Access
• Security
For details, see the Site Preparation Guide.
Many roof types are suitable for AIReach Broadband ODU
installations. Mount installation procedures for the following
common roof types are described later in this chapter:
• Rubber cap sheet/ glued rubber cap sheet
• Loose gravel on rubber cap sheet
• Corrugated metal
The roof type is a factor in the type of mast mount selected. Also,
some mount installation steps may be different, depending on the
roof type.
The following options are available for mounting a mast to
support the ODU:
• Nonpenetrating roof mount – This mount, essentially a
flat platform assembled from a kit, is suitable for most
applications. It can be used on various flat roof types. For
details, see section 5.5.
• Existing structure – An existing structure such as an
antenna tower can be used as a mast, or a mast can be
mounted to the structure, if the structure meets the
requirements given in the Hub and Remote Terminal Site
Preparation Guide.
