straight edge to the satellites (see figure 19).
With the azimuth and elevation to the satellites known, select possible mounting sites
for the dish. When selecting these sites, the first and foremost thing is to ensure that
there is a clear and unobstructed view of the satellites. Before installing the dish at a
selected site, check the line-of-sight path to the satellites. Be especially concerned
about:
• Tree growth.
• Foliage.
• New buildings or additions to old buildings.
Each of these items can block or reduce the dish's view of the satellites.
