Hello. I live near Wrocław. Tv only finds me only TVP on a digital signal? Why is this happening? It only receives MUX3 The rest of the programs have been turned off? I have: TVP 1 TVP 2 TVP INFO TVP POLONIA TVP KULTURA TVP HISTORY And that's all What is it about?
http://www.sat-charts.eu/nadajniki.php According to this, I should receive all MUXs. And I only receive MUX3 Until today I have been receiving MUX2 and MUX3. Today turns on the tv and you lipa is not receiving anything. I turned on the tuning and it only found MUX3. On MUX3, when I watch now, the image is stuttering and the squares are there
first I checked the connection from the power supply. I checked if the antenna cables were not short-circuited. Then I checked the plate in the antenna. It's okay. Nothing flooded, no patina. Antenna front and its connection correctly.
I would start by replacing the antenna amplifier (the famous "antenna board") for a balun.
This: [...] I have removed the link to the auction. 3.1.18. (10.11) It is forbidden to publish information for sources that expire after a certain time (publication of links to pages of a short-term nature). GM
1. I would do MANUAL tuning for k. 58. 2. If it does not help, as I wrote: instead of "PCB with amplifier" I would use a balun.
Probably the amplifier is distorted by the POLSAT analog signal on page 59
In severe frosts, the propagation of radio waves is much better than during "normal" temperatures. The higher the frequency, the signal grows much stronger than for lower frequencies. Unfortunately, when the frosts lessen, everything will return to normal. Although Oborniki Śląskie is 50 km from Ślęża, the mountain itself (with a transmitter) is perfectly visible on clear days. I used to admire the views from the church tower at Trzebnicka Street. The signals are very strong despite the distance. The balun costs about PLN 2, put it on instead of the amplifier and it should be fine. Replace the plug with the power adapter with an ordinary plug.
Using a 45 dB amplifier is a shot in the foot. What alledrogo hustlers will not come up with ..... I would set up a balun with channels up to 69, MUX1 will be broadcast on channel 64.
Instead of an amplifier, you put on a balun, preferably one with a band of channels from 6 to 69. The amplifier is unnecessary and even harmful. And certainly not one that amplifies 45 dB. This is some devilish invention ..... You can do tests, but with the amplifier max 15 dB. At the receiver, instead of the plug with the power supply, you put on an ordinary plug. So much.
If you now have the antenna behind the amplifier - the power supply at the receiver - you can use the old plug, but you simply do not put the power supply "into the electricity". The balun is not supplied with power, it is a short-circuited circuit for direct current. Each balun has its own operating range, in your case it must be a channel range of 6-69 because the lowest channel is 12 and the highest - what it will be - is 64.
Signals are received using an antenna, not an impedance transformer. The balun is an ordinary transformer, but at much higher frequencies.
I do not know if I am allowed to interfere in such a constructive discussion, but ... most often there is a balun on the amplifier board, and in this case it is enough to bypass the amplifier by connecting the output from the balun with the cable going to the TV.

To begin with, you have to have a faint idea of how to do this.
... most often there is an impedance transformer on the amplifier's board and in this case it is enough to bypass the amplifier by connecting the output from the impedance transformer to the cable going to the TV.
Of course there are symmetrizators there - but I suggest to my friend's current knowledge MrDrake92 do not confuse him and the expense is probably about PLN 2. .

I see. And why give an ordinary plug? Without power adapter These cards 6-69 mean the channels that are received on this symmetrator?
No offense, but here you can see the state of this knowledge and that is why we are here and we want to help our friend or guide him.
And why give an ordinary plug? Without power adapter
because the antenna plug from a typical antenna power supply (black " buns ") + an unconnected power supply (or even connected, unfortunately ...) can quite significantly reduce the quality of the received DVB-T signal, which generally reduces the limit of stable operation of the DVB-T receiver. In other words - reception may be sensitive to variable weather conditions (or other), causing significant differences in the signals reaching the antenna, and as a result of the quality change in the received DVB-T signal.
A bit convoluted, but the conclusion is obvious - if you do not use the amplifier in the antenna, you should replace the antenna plug from the power supply with another, preferably all-metal, or a combination: F connectors (matching the diameter of the antenna cable) + FF-IEC transition (M) . Sometimes, to make your life easier, you can additionally screw between them angular transition FF-FM
And if we use an amplifier in the antenna, we should rather use voltage separators in such embodiments plus an ordinary "bread" type power supply with a jack plug or normal antenna power supplies at all, In this climate .
But, yes, from the simplest combinations - did you check if the antenna did not move / twist? Sometimes a more or less minor adjustment of the antenna position is also enough to eliminate the variability of the incoming signals, especially since there is a large angular distance between the transmitters: oh yeah . Enable the 'Satellite' option, find your home and move the green arrow there.
It is like that. Over the past week, the channels have been very well received. 14 channels. There were all TVP, tvn, polsaty, etc. And since yesterday evening there has been none. I have Tv as above. It has mpeg-4. What is the cause of the lack of channels? I scanned manually and automatically and it did not find. Maybe there are some jobs? Tests or something similar?
The plug did not fall out. According to this, it is not the fault of the plate with the antenna. I switched the TV to analog terrestrial television, and the picture was terrible. I noticed that when I disconnect the power supply from the mains, the picture improves. The power supply is 100% efficient because on the second TV it worked flawlessly. I checked it on 3 power supplies and each one had it when I turned off the power supply from the network the picture was getting better, and when I connected it again, the picture got worse. Will replacing the plate in the antenna help? I plan to replace it with a balun.
The discussion revolves around a user near Wrocław experiencing issues with receiving only TVP channels on MUX3 while being unable to access other multiplexes. The user has checked their antenna installation, including connections and the antenna itself, which is a mesh type directed at the Ślęża transmitter. Suggestions include verifying transmitter maps, performing manual tuning, and replacing the antenna amplifier with a balun to improve signal quality. The user confirmed that after replacing the amplifier, the reception improved significantly, allowing access to multiple channels. Summary generated by the language model.
