4.3 With the Help of the Sun and a Protractor
Find the difference between the solar azimuth and the satellite azimuth for the desired time.
The shadow from the sun will point to this angle in case of exact orientation towards the satellite.
Print the protractor. (You can use the compass dial as a protractor.)
Attach the protractor to the LNB bracket (180 forward), push a match or a toothpick through its center:
Match the shadow with the previously detected corner by revolving the antenna on its axis.
You can see the table of solar azimuths for the current day. You can print the table and use its data during the mounting process.
