Installing ODUs 6–7
RT installation
2. Determine (approximately) how high on the mast to install
the temporary installation collar:
a. Determine the approximate desired antenna
installation height:
The ODU/antenna must be installed in line of
sight with the hub terminal (HT), with no
obstructions. As a general rule, install the RT ODU
as high as possible on the mast to avoid obstructions,
unless the work order or RF survey specifies the
ODU height.
b. Refer to figure 6-5 for the collar position relative to
the installed antenna position.
As shown in figure 6-5, when the antenna is installed
(later), the top of the collar is below the antenna
center and above the bottom of the antenna.
