First of all, you have to find an appropriate place. The requisites are two:
-- The chosen place must allow the correct orientation of the dish to the satellite. Use the compass.
-- There can not be any obstacles between the dish and the "view" to the satellite.
Take the "L" wall mount, and attach it to the wall manually. Mark the positions of the future holes on the wall.
Now, drill the four holes. Take into account the right diameter (see the number engraved on the wall plug). The ideal depth for the holes is about 0,5 cm + wall plug length.
Metallic wall plugs. How it works ?
Insert the four wall plugs in their holes, take the helping tool in each of them, and use the hammer to fix them.
Now take the "L" wall mount, and screw it on the wall using also the washers.
Depending on the brand and model, the installation process will vary. Take a look at the instrunctions booklet.
Anyway, I show you mine:
Mount it all, including the LNB, and screw on tightly, except the screws that I marked on red. This is because you will need to turn and move the dish to point it to the right direction.
Wich satellite should you point the dish to ?
It depends. You should have a view at lyngsat to find out what satellite is the most interesting for you. Then, you can download this small app, Satellite Finder or visit Dishpointer to get the azimut, elevation and polarisation.
Well, it is time to point your dish.
You need three pieces of information : azimut, elevation and LNB polarization / skew.
Azimut
This is the dish position in respect to north. It is mesaured in degrees.
Elevation
This is the satellite signal beam inclination that reaches the dish. It is measured in degrees. To adjust it, you must have a look at the numbers on the rear side of the dish.
Polarisation / LNB Skew
The polarisation is the LNB rotation in respect to floor. It is measured in degrees.
All these pieces of information depend on two factors:
-- Your geographical location.
-- The position of the satellite you want to point to.
A practical case, pointing to Astra satellite in Madrid (Spain)
We have found out the three pieces of information.
Azimut, 147º
Firstly, let's move the dish using the right azimut.
Mark azimut (147º)
Locate north with the compass, and turn the piece of paper until the two "norths" are lined up.
Turn the dish according to the mark in respect to the center.
Elevation, 38º
Let's elevate the dish. Skew the dish until the right position is reached, looking at the numbers and nut on the dish support.
Polarisation, 25 º
Use the piece of paper that you printed before.
If the polarisation value is negative, you must turn back the piece of paper.
Well, it is done.
You must do the final adjustments using the receiver's signal strength indicator. You must modify the previous dish positions, very precisely and smoothly, until optimal signal quality is obtained.
