TV antenna repair

Despite the fact that modern technologies allow the use of advanced devices, there is still a demand for such televisions as those with an antenna in the apartment. However, malfunctions and various problems often occur. In this regard, it is important to know what to do in such situations. In this article we will consider all the possible issues that every user may encounter.

Types of TV antennas

Of course, you first need to decide on the type of device you have. Thus, the following models can be distinguished:

• Wave channel. As for the specifics, it is a collection of some elements: active and passive. Here we should add a division into two-, three-, seven-, eleven- and sixteen competent component antennas. They all have different gains, from 5.1 dB to 13.5, respectively.
• Split vibrator. It also has an underlying structure consisting of wave, half-wave, and quarter-wave structures. It can be noted that the unit itself is an analogue of a conventional indoor antenna.
• Loop structure. Use as a reference instrument is often seen.
• Log-periodic. The main advantage is the ability to achieve a wide variety of frequencies.

REFERENCE. There is a limitation in the low range.Excellent in setting the room to search for a huge number of channels on the TV.

• Frame.
• Common-mode array.
• Traveling wave antenna.
• Polish.

Why doesn't the antenna on my TV work?

Let’s look at the most popular and frequent situations that occur among owners of the equipment presented.

1. The most trivial reason may be a cable failure. Indeed, the first thing you should do is check the serviceability of this particular component. The fact is that matching the wave impedance is very important.
2. In addition, there is a possibility that the tuner has failed. There are cases when nests are damaged or various components deteriorate. Then you need to call a qualified technician who will surely correct the situation efficiently.
3. Burnout of individual parts or various mechanisms. Here you also cannot do without the hands of specialists.
4. Incorrect frequency settings. The inability to find channels is a consequence of the occurrence of such a defect.
5. Technical problems that arise directly from the provider. In such a situation, you should definitely contact the hotline, where you should be advised of further actions.

What factors affect signal quality

Below is a list of all possible physical aspects on which the degree of signal delivery directly depends.

• Diameter of the antenna used.
• The power that is emitted through the process of work.
• Noise figure and its temperature.
• The stability of the device is adequate in adverse weather conditions.
• Initially configured polarization.
• Satellite station holdover accuracy indicator.
• Signal in a situation of dispersion due to various obstacles.These can be buildings, trees, or birds and airplanes.
• Presence of precipitation such as rain, hail, snow. This can also include the occurrence of the lowest possible degree or significant humidity in the atmosphere.
• Characteristics and parameters of the receiver.

Thus, one can easily notice that quality indicators can be both long-term, extended, and temporary, for example, the flight of a flock of birds. But, in any case, one way or another, they all affect the performance in their own way and affect the process of watching TV.

Functionality check

For the action itself, you must first go to the TV menu, and then perform the following steps in the presented sequence:

• Then you can go to the “settings” section and click on the “search” button.
• The device will give you two paragraphs, the names of which are “power”, and the second one is “signal quality”.
• Then there can be two outcomes of events. Either you will have access to the two previously mentioned scales in color format and with a percentage indicator, or the opposite of what was said. In the first case, it refers to a temporary cessation of performance or its absence. In another, the position indicates the presence of a problem. That is, it is worth rebooting the entire device. And then start from future actions and move directly to the serviceability of defects - they will be discussed below in the article.
• If you purchased a new design, then you do not have to check it yourself. You just need to find out from your neighbors that they live near you about the provider and, based on this, make certain calculations.

TV antenna repair

In any case, it is important to take care of such a moment as the location of the structure itself. It is recommended to beware of various obstacles that could harm the resulting image quality. In addition, it is advisable to equip the equipment with an additional amplifier. Thus, the effect of improving the picture will be noticeable. In addition, if you have an old antenna, it would be better to replace it with new equipment.

ATTENTION. Indeed, choosing the right amplifier makes a difference in performance. In the worst case scenario, a continuous ripple appears on the TV across the entire screen. Therefore, you should correct it to a weaker coefficient and check the settings that fit directly to the cable.

By adjusting the power supply you can also adjust the voltage contact. However, it is very important not to damage the device. So it is in this situation that the best option would be to call qualified specialists who will definitely be able to carry out all troubleshooting steps efficiently.
