hello guys

the Polarization change

I do not know why

now if i want to search through ( channel search ) no channel showing ?

i must search through ( scan transponder )

And change the polarization for each package

how i can fix that ?

Did you tilt the LNB to a side, instead of mounting it (almost) vertically?
On a linear LNB this would invert the polarisations.

Or do you use a multiswitch and by chance cross changed some of the input cables?

Or do you use some custom transponder list, like for American band stacking LNBs?

Please provide full details on your dish / LNB / switching system and bird(s) you're on.

First

I used

Diseqc switch 4x1
Dual LNB
these satellites

example-1
example-2
example-3

in first time the polarization true


i just changed the location of the satellite 1

example-3
example-2
example-1


the Problem began

i returned back


Still problem ?

Dual or Twin LNB?

According to European standards, a Dual LNB comes with two fixed outputs, one for Horizontal, the other for Vertical. Cross changing those would of course also cross change polarisations.
Just using one port on such an LNB means to only be able to get one polarisation.
Dual LNBs are made for use with multiswitches only.
Trying to use them on DiSEqC switches instead is NOT within the standards.

A Twin LNB instead comes with integrated polarisation switching, controlled by supply Voltage, 13 Volts for Vertical, 18 Volts for Horizontal. On those, both output ports are behaving identical and independently. Connecting both ports to one DiSEqC 4/1 won't make any sense. One's enuff...

BTW, IF you are talking about America specific LNBs, forget about all above, hit dvbn(dot)happysat(dot)org, to hopefully get helped by other Americans using the same style of proprietary hardware, we never come to see over here in Europe.

no sorry Twin

one for Receiver and one for another Receiver

All channels are working properly on the Receiver

but not working good on the another Receiver ( the Polarization change )

and As I said ( first time the

Channels was working properly on the program )

After adjusting the location of the satellites changed


But no change in the first Receiver

Your LNB may be bad.
Cross change LNB cables, to be sure or exclude.
Also check the connectors for corrosion and alike, as shielding discontinuity or other bad contact can cause things like this.
