Volleyball antenna and interference in terrestrial TV reception

Welcome. The above subject brings me to a white fever. In a single-family house, there has been a problem with terrestrial TV reception for about a year. I have a mesh antenna (about 20 years ago) and until recently everything worked perfectly. Recently, in the evening, there are always problems with the reception of most channels. It lasts from around 18 to 22. The antenna is on the amplifier. What could be the reason for this situation? The house is standing in a field, it is rather unrelated to the disturbances. Below the distance from the transmitters.



Is the antenna eligible for replacement? Or maybe replace the amplifier PCB in the box? Replace with a balancer? I have no ideas. If possible, I would like to avoid replacing the antenna. I will also add that it is quite difficult access to it, so I would like to prepare myself as soon as possible for her to repair, as I will take it.

For help in the topic I offer a large beer in real life!

This description indicates that it is not the fault of the antenna and interference.
Begin by repairing the power supply or replacing the power supply with a new one, preferably with regulation, because it may possibly be the result of voltage drops.

@LeDy thanks for the feedback.

I will add one more thing - maybe essential for the initiated. If at the time when there are interference in the reception, I turn off the power supply of the amplifier, then for most channels I have no signal, but some are starting to work. Strange thing.

In the sentence above, there may be an answer. The antenna is rusted through, the amplifier worked in the water, no information about the length and quality of the cable was given. The power supply can be replaced - a new one will be needed anyway.

If the antenna is not corroded, replace the amplifier with the power supply, connections and everything will be back to normal.
Check the condition of the cable.

With this rust, I would not agree to the end I think it's galvanizing or something, it looks pretty good. It cost her a little at some time In any case, my plan of action is as follows and please correct me if I wrote wrong:

1. Buying the power supply with regulation



If it did not help:

2. Buying and replacing the amplifier PCB in the antenna box.


If it still does not help:

3. Purchase and substitution of the antenna itself.

Also remember about the coaxial cable.
It should not be too bent:

o acceptable radius for bending cables in internal installations should not be less than 5 times the outer diameter of the cable, and in external installations not less than 10 times the outer diameter of the cable,

the cable is relatively short (about 6 meters from the TV to the antenna) and is certainly not bent. I think that if I earn the tip again, it's enough when it comes to its maintenance. the insulation is not cracked.

PS from what I know, the antenna is permanently attached and I do not know whether to buy a new one, to do it, and not to mount it in another place and peace. Is this net for 30 zlotys good? or invest in some more expensive reticulated? In the sense there is a large discrepancy in the quality of workmanship and the new antenna itself at this price can significantly worsen the reception?

Because when I look at the prices of such components in the electro store, it comes out next to me; amplifier about 10 PLN, power supply about 10 PLN and antenna about 30 PLN. Is it right to act? Is it cheap and there is nothing to play with?

It's only when it starts to corrode.
When choosing, do not be fooled by the type designations:
Full HD

ie? in the sense, if the antenna will be more expensive and will have fhd in the name and will be cheaper and without it, it's still one dog?


because it would not be, this mesh antenna I have is the same as in the picture in my post above and I am going to buy the like. Some say that the better one would be directional (I read so) but I'm afraid that then mux 8 will fall off me. And on the old volleyball at the right time of the day, he looks for these channels and works.

The antenna has to provide a sufficiently strong signal to the TV tuner and has no effect on the image resolution.

If mux 8 broadcasts from a different direction then it may be.

This may indicate that you have a big signal. Power supply with regulation and should be after the trouble without any exchanges of other ..

Of course I know what you mean.
But from such a distance?

And what?? As the amplifier without power receives it must be a large signal.

Not so big that this amplifier suddenly overdrive; the more so because:

After 20 years comes a moment that "worked perfectly" goes into history contacts are corroded oxidized connectors loosened and the cable has microcracks and to this lingering belief in the nation that the amplifier and power supply make a miracle - the installation is suitable for exchange because resuscitate it at selected points on next 20 years is certainly not enough and in the installments you will need to replace everything - so it's better to do it once and for all - choose a large mesh antenna with a balancer and combine passively - the less elements in the track, the less risk of interference - find the strongest signal and then you decide do you need an amplifier - the antenna remembers the times of a deep analogue and no one felt it at that time - the creation of digital television - the holidays have changed and the level of technology also - it's time to go with the times

There is one more problem that Electro has to write a lot about: Internet access networks in LTE technology in the 800 MHz band, ie on +61 channels have been operating in Poland for about a year. All you have to do is have a neighbor with an LTE terminal within a kilometer or BTS operating in this technology and within this band within 2 km, you can say goodbye to using any broadband antenna amplifiers. Even if you exchange an "antenna" for an "antenna" and put on another amplifier, the situation may be the same or even worse.

Maybe the first information you need is: where exactly you live, because that's where we know around Lodz. All you need is the position, name of the (small) town or a nearby intersection of streets.

I suppose it's about Łowicz or around; in Łowicz itself you have 5 BTSs in the 800 MHz band - four Sferia and one T-Mobile. Friends from Lowicz have signaled to me that "there are eggs" .....
I will just add that writing to UKE is pointless, when they come and see a volt-grid antenna with an amplifier, they refuse to intervene.

That is only a directional antenna with LTE filter.

That I will not tell you 100%. Each antenna is always selected for specific conditions and a specific place. A good and effective LTE filter is a considerable expense, it is not known for how long it will last.
I asked a specific question: LOCATION?
