Before proceeding, use the installation software to determine the
initial values to use for setting azimuth, elevation, and tilt. Record
these values and keep them handy for reference as you install and
point the antenna. To use the installation software, follow the
instructions in the IDU installation guide for commissioning the
IDU.
General instructions for
assembling the antenna
Before you assemble the antenna, read these important
instructions:
•
Mast – The mast must be installed before you can install the
antenna. For information on antenna mounting methods, see
the HughesNet System Antenna Site Preparation and
Mount Installation Guide (1035678-0001). The mast must
have an outside diameter of 2
3
/
8
inches (2.375 inches).
•
Sequence of steps – When you assemble the antenna, follow
the instructions in this chapter in the order they are
presented.
•
Tightening hardware– Do not tighten any nuts or other
hardware until you are instructed to do so. (See also the next
item, Torque.)
•
Torque – To ensure successful installation of the antenna, you
must tighten all nuts and socket-head cap screws to the
maximum torque values shown in Table 6. This is a critical
requirement.
For bolts that use a split lock washer, tighten the bolt until the
washer is flattened, but do not tighten the bolt further. When
the washer is flattened, this indicates that sufficient torque
has been applied.
