Ok score in 5 minutes

We must learn a minimum on the Internet to indicate the correct transponder settings - the default of Satfinder Astra were incorrect (the best is when it is possible to apply those we can meet on the menu adjusting its demodulator: Sagem my Astra 19.2 and TNTSat: 11856-27500 - DVB-S2 - Vertical) and get an idea of ​​the elevation and Azimuth before putting it by searching longitude / latitude on an internet map (in decimal), then by educating them on the SatLex calculator for example.
Then once the Satfinder configured, the tour LNB approximately x degrees as indicated by the computer (LNB tilt proposed by the utility Safinder was false, that of SatLex ok), find a "quality" signal by a rotation / elevation of the dish very slow (the Satfinder will beep as soon as he hangs a minimum sattelite, if you have not disabled the Buzzer function ...).
And once Max got QUALITY, think optimize the signal by adjusting the rotation of the LNB.
Not surprising then that the levels of the signal strength and quality are different between Satfinder and demodulator, which is shown higher on the demodulator (86/67 -> 95-90 for me).
In 5 minutes by completely reinstalling my parable fiberglass and changing my head for a single-IDLB Inverto Black ULTRA-SINL40 purchased on Amazon, I went from a 70/60 to a 95/90 signal, no more jerks on overcast screen TV ...
NB: If you need to redo your cable connector sattelite, contrary to what we find as little old tutorials, try to wrap the braid down the insulation and screw over the connector; rather than letting exceed the braid, screw in the connector and then cutting away excess ... and always put a rubber cover to protect it.
