4. With signal meter locked and displaying a value greater than 0, adjust the azimuth
until the signal meter value is maximized. Then further maximize the signal meter
value by finely adjusting the elevation angle. Make a note of the elevation and
the azimuth angles where signal meter was the highest. The elevation angle can be
read from the scale, the azimuth angle can be noted by marking the mast and
antenna bracket using a pencil, crayon, soap, etc.
5. Switch signal meter to satellite 119
°
(this might also be represented on-screen as
“Satellite 2” or “Satellite B”). If the antenna, mast and multiswitch have been
installed properly, signal meter should be locked. For many parts of the US, the
optimum Azimuth and Elevation settings for both satellites will be almost the
same. However, for some parts of the country in the Northeast and Southwest,
there might be slightly larger differences in the optimum settings between the
satellites. If no signal is available, check the connections to the multiswitch.
6. Once again, sweep the azimuth until the signal meter value for satellite 119
°
is
maximized, then adjust the elevation to peak the reception for satellite 119
°
. Make
a note of the elevation and azimuth angles.
7. Switch signal meter to satellite 101
°
to make sure that signal meter is locked for
both satellites.
8. For installations where there is a difference in settings, adjust the Azimuth and
Elevation settings halfway between the optimum points that were noted for each
satellite. This will ensure the best performance in adverse weather conditions.
After adjusting antenna, make sure that signal meter is still locked for both
satellites.
10. Carefully tighten all of the bolts, trying not to move the antenna on the mast while
you do so. When done tightening the bolts, make sure that signal meter is still
locked for all satellites.
• If the antenna moves or the signal meter values change significantly lower
while tightening the bolts, slightly loosen the elevation bolts (so they are
still somewhat snug), and adjust to maximize signal strength; then
carefully tighten them again.
