iDX Release 3.3
2 Site Considerations
This chapter provides general guidelines and principles for the location, assembly, and
orientation of the VSAT antenna that are applicable to all installation sites. Refer to the
antenna manufacturer’s documentation for specific installation and operating instructions.
This chapter includes the following sections:
•
“Selecting a Site” on page 7
• “Assembly” on page 7
• “Orientation” on page 8
2.1 Selecting a Site
A comprehensive site survey is beyond the scope of this guide. However, keep the following
general guidelines in mind when selecting the site:
•
Select a level surface that is approximately 10 feet by 10 feet.
• Avoid proximity to other transmitters.
• Avoid exposing others to incident radiation.
• Verify a clear line-of-sight to the satellite.
• Consider availability of electrical power and routing of cables (power, IFL, LAN).
• Verify that the coaxial IF cables (Tx, Rx) can reach the Satellite Router from the selected
antenna location. RG-6 cable may be used up to a distance of 250 feet. If the run is
longer, RG-11 cable must be used up to a maximum distance of 500 feet.
• Ensure that cables do not cross roads or foot-traffic areas.
2.2 Assembly
Assemble the antenna and mount by following the manufacturer’s assembly instructions. After
installation, ensure that:
•
The antenna base is fixed on a stable surface that will not shift.
• Ballast is installed on the antenna base (to combat wind).
• The mast pipe is plumb.
