Determining the Elevation and Azimuth:
Compass:
Rotate the Compass until the painted tip of its needle is on the Zero or (N) mark on compass face for proper orientation.
The EAST will be at the 90 degrees, the SOUTH will be at 180 degrees and the WEST at 270 Degrees.
Azimuth (Magnetic):
Move the dish Left and Right until the LNB arm is pointing to the magnetic azimuth value for your location.
Elevation:
Move the Dish up and down and set the elevation indicator on the value of the elevation value for your location.
Elevation Indicator:
Be sure to locate the Elevation indicator ( or equivalent , depending on your dish) .
Use this indicator to set the correct elevation of your location.
The satellites are "parked" approximately 22,300 miles above the equator.(36,000 km) In reality, the satellites travel from west to east, but to us on Earth they appear stationary because they match the exact speed of the Earth's rotation. (This is a geostationary orbit.) If you stand up now, turn towards the southern hemisphere, and tilt your head up to the heavens, you'll be looking in the general direction of our satellite.
To find out the azimuth and elevation angle for your location,
Please download the following program and install it on your PC.
satcalcv05.exe
satpos.dat
This program will calculate the elevation and the magnetic azimuth of your location where you are going to install antenna.
Now that you have your azimuth and elevation coordinates, what do you do with them?
First, survey the site to ensure an unobstructed view in the direction of the satellite.To receive broadcast signals, your satellite dish needs to be positioned correctly. Mount your satellite dish so that the base fits flush with the mounting surface (level if mounted on a flat beam or roof, or on an angle to match the pitch of your roof line). When you have securely mounted your satellite dish, adjust your dish so that the dish mast is plumb, that is, exactly perpendicular to level - this is best achieved using a carpenter's level. With your dish now mounted and properly set, you are now ready to aim your dish toward the satellites.
Be happy with the dish antenna installation,
see you next time!
첫댓글 I prefer the "mkon's SatCals" to "SAA" to calculate the azimuth and elevation. Because it gives me Skew too but SAA does not. The SAA has the "sun's azimuth" and I think it is really good function and helpful for person who is going to install a new dish antenna.
