Select the installation site
Before selecting an antenna installation site, check OASIS or the installation
reference sheet to see if there is a customer preference for the installation site.
Work with the customer to see if a line of sight (LOS) is available at their preferred
site. Refer to the appropriate antenna site preparation and mount installation guide
that discusses the factors you should consider when selecting an installation site.
The first and most important consideration when choosing a prospective site is
whether the site can provide an acceptable line of sight (LOS) to the satellite.
Choose a site where the antenna will be able to receive the strongest signal
available. A clear, unobstructed view of the southern sky is necessary for proper
transmission. Consider obstructions that may occur in the future, such as
construction in the area, or the growth of trees.
Also, consider potential grounding sources when choosing a location. For guidance
on grounding, see the documents listed in
on page 43.
As with any type of construction, a local building permit may be required before
installing the antenna. It is the property owner's responsibility to obtain necessary
permits and comply with local building codes.
