Help on Lnb/Installation issue

Hello beloved community! Today I was trying to swap between satellites first the dish was on INTELSAT20@68.5°E with sig~68 qty~65 next I tried to align it on Yahasat but I got sig~56 and quality no more than 4-15% I tried to return it back to God channel but quality still show up no more than 15% I even used satellite finder to make the job easier but no result at all is there any possibly I Cound have damaged the LNB?or is there any other problem please help me fast??,

you are probably not adjusting the skew angle to its proper position, or may be there was a big
cloud passing by . If you have an extra LNB it would be good to give it a try.

Thanks Kstar I really appreciate but just moments before climbing the roof the dish was perfectly working please once again tell me if I could damage th lnb in anyway as I am not an expert Thank!

My take is that you lnb is just fine but the skew angle(which is the angle you adjust by rotating the lnb)
is not adjusted to its proper position. different sat have different skew angle, for example yahsat
is around 54 degree to your left where as God channel is around 73(you could find the exact figures from my other posts).

But there is always a possibility that the lnb is fired. That usuall occured if you put the cable
inplace while the receiver power is on. Usually diseq switches are more likely to faile that way
than LNbs do. Also take out any diseq switch in betwee(if there is any) and connect it directly to
the receiver(to see if it is not a case of a dead switch).

If you have another LNB which you use it for nile sat forexample, take out that lnb and put
inplace the one you used to use it for intelsat20, then adjust the skew angle there. Then you
will find out if the lnb in question is bad or not.

from my experiance,if you had it hit hard with something or if it were droped on hard surface, they are more likely to faile. But they are more resistance and tolerant to receiver power fluctuation or surge current.

Thank but one think I remember is I connected the sat finder after a getting up on the roof

We all do that, and there is very little risk of getting the LNB fired.
Thogh from science point of view, it is not recomended to power on the receiver power while
connecting or disconnecting cables from the other components in order to protect
those components frome surge current( a current created by an inductor when the voltage level changes from some value to zero in a split of seconds).

Electrostatic discharge is the other phenomina that causes this devise to faile, if you had
touched the lnb and noticed a bit of a shock then there was electrostatic discharge.
But this kind of things happens so rearley in dish installation that it is a good bet to think that
your LNB is still good.

If you are afraid of touching your other dishes, then align this one to nile sat with bbc frequency,
I am sure you will get strong quality there to asert the integrity of your LNB.
