Select the 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
Ground connections on page 39.
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.
