LNB Short Circuit: Identifying & Resolving Signal Loss from Antenna to Socket (N) Connection

I have a problem because I wanted to put the signal from the antenna from the N into the socket and pick it up in the other room from the socket (so that I did not have to pull the cable) the antenna and the signal were set up nicely so that I could be sure that it is well positioned, but when I plug in the sockets, it pops up I will add "LNB SHORTED" that I dismantled the sockets and tried to shorten the socket and nothing helped. I would like to add that earlier in the apartment (the previous owner) there was a cable cable, but from what I can see, the cable on the cage is cut off. I don't know what to do about it

Unplug the cable from the converter and check at the other end if you really do not have a short circuit.

You have a short between the center line and the screen. Check with an ohmmeter without connecting the devices, maybe there are cable TV filters that give a short circuit for the DC component (voltage supplying the converter)?

I will add that I am doing it for the first time in my life how do i check it?

But why is everything ok when I connect directly from the antenna?

And what are your sockets? TV-RADIO for sure!
And here it gets short-circuited!
You must have RTV-SAT end sockets.
Check the cable as those colleagues have already described.

and how to distinguish them ??

Here you have a TV-Sat final. http://www.dipol.com.pl/garówka_gar-bg-dk-sat_natynkowe_koncowe_R62195.htm

yesterday I struggled with the sockets and it turned out that in the third room there was a short circuit in the socket. The short circuit is gone, but the signal is not there, I do not understand it.
Is this due to the fact that I have to change the sockets for the satellite TV to those with a screwed input or maybe the sockets are not connected to each other? But on the other hand, if they were not connected, the short circuit in the third room would not matter to the rest ... I don't know, but that's what I came up with. How can you check if the sockets are connected to each other, e.g. two specific sockets? I would like to add that by briefly twisting the cables from the socket (all were unscrewed) nothing helped and there was no signal.

The easiest way in your case is to connect the batteries at one end and the light bulb at the 2nd end and you will see if they are connected. You won't do anything without even the simplest equipment. Buddy kermito83 if you don't know it, ask a friend or some electrician, it will help you because it's a waste of your time.

Only such a socket ensures the transmission and connection of the satellite signal from the antenna to the tuner.

An electrician in this case can do harm, not help!
There are SAT-TV installers for such cases and it is best to go to one and ask for the service.
I can see that even these hints did not get you anywhere or you are so dumb.
I wrote once to replace the sockets and you still yours.
The cow is smarter and does not offend anyone.

Do you have at least an ordinary "digital" multimeter?
If I were you, I would look "by the thread to the ball" where you still have a break / short circuit, and after eliminating them, I would "pin" the wires from the antenna to the tuner so that they would constitute a "continuous" circuit (of course, taking care to "short-circuit" ). As if other cols were "snappy" , write to me at PW.
Good luck.
