No TVP1, TVP2, TVP3 Signal on Second TV with Passive Antenna: Troubleshooting Guide

Hello, I have a passive antenna installation. I split the signal from the antenna into two tvs and in one it receives all the channels, while in the second tv does not want to receive tvp channels (1,2, region, sport, culture ...). Usually it is so that I turn on tv on channel 1 there is tvp 1 for a short while the image is nice then after less than a minute it starts to stutter and then disappears and the message about the lack of signal pops up. Where to look for the reasons for this state of affairs?

Hello. What type of signal splitter do you have from the antenna model?

Is the signal level from the antenna / splitter sufficient? What is this TV?

Provide at least the distance from the transmitters and the location, because you cannot guess without it.

What distance to the transmitter? - the signal may be too weak to be split between 2 TVs.

Let me remind you that this is a digital signal.

If it's ok on one tv, it shouldn't be a problem on the other.

Added after 38 [seconds]:

There are different methods of finding a fault.

Added after 3 [minutes]:

Do you have ektenia squares on other programs? Swap the cables in the splitter. See what happens. Do you have the option of replacing cables or connecting with a new cable for shortcuts?

Added after 1 [minutes]:

Is the antenna external or internal?

It all depends on the difference in cable lengths for TV and the type of splitter. Maybe there is an unbalanced damping. Enter your location, the antenna (type, model, symbol) and where it is installed - balcony, attic, roof, ... and on what floor ...

So what if it's digital? First you write this and then ask for the rest?
Even if "weak" one device will still work and the other will not.
The rest is up-to-date, that is - what does the installation look like and where and from where, what devices, what are they separated, what signal levels etc.

A lot. Two televisions side by side. DVBT antenna. Splitter. One tv ok the other no. Why?

Little data. You need a detailed description of the installation and the location of the collection point.
@olomajdan - whether this subject applies to the same installation or location ?

https://www.elektroda.pl/rtvforum/topic3402137.html

this applies exactly to this installation and location, only two TV sets are currently connected, one on the ground floor (the antenna cable is much longer to it, but this TV is fine, I will add that this cable from the splitter is not connected), I used the splitter as recommended and colleagues in the previous topic of the telmor company. the antenna is placed on the ceiling height of the 1st floor. I will add that currently I do not use the second branch on 3, only instead of a branch there is a barrel connecting two antenna cables and the other two are not used. I will just add that everything worked fine and the situation worsened when the first splitter (on 2), which was originally located at 250 centimeters of the cable, moved closer to the antenna from the antenna and is now mounted 15 cm under the antenna on the mast.

Flooded damp manifold. However, with the dvbt signal, it still does not convince me why TV is ok in one and not in the other. Could it be such a large suppression. Put the cable from the antenna in and there is a splitter. Try to keep the length of the cables at least similar.

For what? This is an ordinary antenna and regular television does not require satellite data.

the manifold is protected against moisture. the location is the Royal Maidan, Kolbuszowa poviat and the antenna is set to Rzeszów "Baranówka". finds 21 channels

The TVs differ, for example with the sensitivity of the head. Swap televisions for the test.

And then what? And what is that side-by-side combination to suit you?
Didn't he read it?

Do you think that how digital is so smart that it can recognize two connected receivers and add more to those who have even weaker sensitivity?

Is it supposed to cut cables for you, move equipment close to you to convince you of something? And if they are different, you don't know what to do with it? If the signal is big enough, it doesn't matter if it is 5m or 20m.

It's just plain not digital?
Where did you read the satellite here? These are the data that others are asking for, it has no meaning in the reception, but it is only digital?

Baranówka (azimuth approx. 160 °) is the local illumination of mux-3 for Rzeszów and the signal does not reach you. The azimuth to the south is Sucha Góra.
If you are receiving the signal from muxs 1-3, you should have 23 programs, not 21.

I suspect that you tune the receivers automatically and then they can program a weaker and worse quality mux-3 signal from Giedlarowa or Tarnobrzeg (sheet 26). If the antenna is set to Dry Mountain, scan manually k.29. The remaining muxs are sheets 32 and 52
