Manual dish pointing

image of a manual Parabola ...This is a small, unpretentious tutorial to capture Fransat ...

I noticed that many of us are sometimes a little disillusioned when it comes to pointing our satellite dish ...
At the time ( not so long ago ... ) when the broadcasts of satellites were in "analog" mode, finding the right satellite was relatively easy.
Today, it is quite different! Indeed, now the image only appears when the pointing is correctly carried out, otherwise the screen is desperately black ...


To help ourselves in this laborious task, we absolutely need two small accessories:

The compass comes from Decathlon , the pointer from Leroy Merlin ...
If like me you pick up your favorite shows from the Fransat satellite , here is my method to get there in ... about 5 minutes ( or less under the best conditions ... ) to make the correct settings ...

First of all, know that you must point your dish towards the Eutelsat 5WA satellite at the 5 ° West position.
Clearly, you need to point your compass to the South, then go up 5 ° to the West.

How to do ?

Proceed as follows:
Apart from the small graduated ruler ( not necessary here ... ), the compass has a crown comprising the 4 cardinal points as well as precise indications in degrees.
The first thing to do is point the compass south, crown towards you. You will then have North on your back, indicated by the direction of the red arrow on the needle.
This done, turn the crown so that the red arrow of the hand is superimposed on the one drawn on the bottom of the crown, therefore towards the N mark for North ...
You thus have in front of you the indication for South materialized by the back of the needle ( gray part ) facing the S markfrom South. You should also see a small dash under this mark, in the axis of the compass. Now, you have to point the satellite going up 5 ° to the West ... match the 185 ° graduation of the crown with the little dash that appears under the crown ...
The red hand is no longer at the Above the mark on the bottom of the crown, rotate the compass slightly so that they match again.
That's done ? perfect, your compass points in the direction of the satellite at the 5 ° West position !

Adjustment...

On the pointer that you will have obtained, there is apart from the level indicator needle an adjustment knob for the volume of the integrated beeper. If you don't have this kind of essential accessory, it will be more complicated ...
At first, increase it almost completely ( watch out for your ears and ... those of your neighbors ... ), make the finer adjustment of the orientation of your dish by carefully manipulating the mast by rotating it to the left or the right from your first adjustment point ( I remind you: position 5 ° West). After some trial and error, you will start to hear the very high pitched noise emitted by the beeper ... then lower the volume a little so that you can hear it correctly and at the same time watch the deviation of the needle. It should start to move towards its maximum ... Then refine the adjustment of your mast, always by very low rotation, in order to really obtain the maximum deviation of the needle. At the same time decrease the volume which is filling up as the needle tends towards the maximum.
After a few manipulations, you will have reached the maximum possible. Then cut the volume of the beeper, the satellite pointer can perfectly remain installed permanently. It will turn off automatically when the power to your decoder is cut.

That's all, generally I need a few tens of seconds ( si-si ... ) or even a few minutes to make my final check-in, the time for Madame to possibly serve the aperitif ...
I sometimes need a lot more time, this obviously depends on reception conditions, geographical location, leafy tree branches, etc.

Useful information for pointing your antenna towards Eutelsat 5 West A:
* case of my personal home
Elevation: 33.0 ° , Azimuth: 194.6 ° , Polarization: 9.55 ° .
The elevation is the opening angle of your dish, but in the case of mine for example, the mechanical counter at the bottom of the mast is not graduated in degrees ... it is only a digital counter simple, which displays for example the value of 0825 for this elevation of 33 ° ... This counter is only an indication, which may be slightly different depending on your equipment and ... the inclination of your vehicle ...
The azimuth angle of 194.6 °is to be found on the graduated crown of the compass ... we will therefore take the rounded value of: 195 °
This value of 194.6 is the true value in degrees to be located on the crown of the compass . You will notice in passing that I indicated at the beginning of the chapter the value of 185 ...
