The antenna in the apartment does not work well. Why doesn't the TV see the antenna?

Instructions

Pay attention to the location of the antenna. The height at which the antenna is located plays an important role in signal reception. It doesn’t matter at all whether we are talking about radio or television. To amplify an indoor antenna, place it as high as possible. If the antenna is a telescopic type, it must be fully extended for best signal reception.

Look where the antenna is pointing. If there are obstacles between it and the signal source, naturally the reception will be poor. Try to position the antenna so that there is no large tree, tall building, power line or any other structure in its path that could seriously interfere with signal reception. This way you can strengthen the antenna.

Use an antenna amplifier to make your indoor antenna more powerful. This is a special device that facilitates signal reception. Also try using additional grounding. This will practically not change the antenna power, but the signal will be clearer. Any antenna is an open oscillating circuit. The larger the area of ​​the oscillatory circuit, the greater the ability to receive a signal it has. Any long wire can serve as an antenna. Attach it to your indoor antenna. This will increase its area, and therefore its power.

Use the last resort if none of the above methods help. Replace the indoor antenna with an external one. An external antenna is much better suited for high-quality signal reception, especially since there are many more possibilities for its configuration. Point the external antenna in the direction that is optimal for signal reception. This will save you from the need to constantly adjust it, as is often the case when using an indoor antenna.

The quality of television and radio signals does not always satisfy viewers and listeners. Moreover, there can be interference even when there is a seemingly powerful antenna. In order to improve quality reception, the antenna must be configured correctly.

You will need

• coaxial cable, portable radios or cell phones.

Instructions

If the antenna is directional, try repositioning it so that there are no obstacles between it and the signal source. Such obstacles can be high-rise buildings or other structures, power lines, and so on. You can try the exact direction to the signal source. To do this, you can use the help of an observer monitoring the signal at the receiver. To communicate with it, you can use portable radios or.

If you have a directional antenna with flat polarization (type “Wave channel” and similar), check the polarization of the received signal. Adjust it according to the received data. To do this, you need to rotate the antenna relative to the axis directed towards the signal source. Most often, just trying to rotate the antenna 90° is enough.

Efficiency antennas can be increased using an antenna amplifier. But in this case, the gain limit is set based on the noise level. To reduce their level, use shielded reduction, that is, the antenna is best using a coaxial cable.

Efficiency antennas, especially when receiving on long, medium and short waves, can be increased by installing additional grounding. It should also be borne in mind that the antenna must be impedance matched with the input circuit of the radio receiver. That is, it must be connected with the type and cable recommended in the instructions for the receiver or.

note

Long, medium and short wave antennas can be long lengths of wire. It is also recommended to install the mounting points of such antennas based on the highest reception volume of the desired stations. That is, it is necessary to change the position of the antenna.

Helpful advice

If we are talking about an indoor antenna, then the best solution would be to install a stationary external antenna. This will dramatically improve the quality of reception. It is also recommended to connect portable mobile receivers and televisions to an external antenna when operating them in stationary conditions.

Receivers operating on ultrashort waves have long been commonplace. We use the radio at home, in the country and even in the car. But as you move away from the broadcasting station, the signal quality deteriorates noticeably. It is not always possible to install an effective receiving antenna, so using an antenna amplifier may be a solution to the problem. If you know how to use a soldering iron and understand basic electronic circuits, you can make one like this amplifier with your own hands.

Instructions

Check out the circuit diagram of the antenna amplifier. It is made using a low-noise transistor, providing a gain of approximately 20 dB. At the input, low-pass filters with a cutoff frequency of 115... 120 MHz and a high-pass filter with a cutoff frequency of 60... 65 MHz are connected in series. This allows you to amplify signals from broadcast stations operating in the VHF range.

Make a list of the required parts. In addition to the transistor, you will need several resistors and capacitors, as well as inductors. The parameters of the elements are shown in the figure for step 1.

Take the transistor type KT3120A or KT368A (the second option is less preferable). It is advisable to use imported capacitors in the device, similar in parameters to domestic K10-17. Resistors of the MLT and S2-33 types will be quite suitable for the amplifier. Wind the coils from PEV wire using a mandrel with a diameter of 4 mm. Coil L1 contains 3.5 turns, and L2 - 4.5 turns of wire.

If you plan to use amplifier in a car receiver, add two relays and an additional power filter to the circuit. When power is applied, both relays turn on amplifier between the antenna and the receiver. When the power is turned off, the receiver input is connected to the antenna. Be sure to equip the car version of the amplifier with a metal case.

Prepare a printed circuit board made of fiberglass, foil-coated on both sides, for mounting the device elements. The pattern of the printed tracks may vary (depending on the part layout you choose). Leave the second side of the board metallized and connect it with foil along the contour to the common conductor of the upper side. Make the board for the automotive version of the amplifier more elongated so that you can easily place a power filter and relay on it.

Assembled amplifier connect between the receiver input and the antenna socket, and make the connection with a short shielded cable if possible. When installing the device in a vehicle, place it close to the receiver in a shielded housing.

Check how effectively the device amplifies the signal. If necessary, reduce the capacitance of the capacitors and increase the inductance of the coils (but not more than one and a half times). Please note that in city conditions where the signal level of radio stations is high, the antenna amplifier should be turned off to avoid signal distortion.

To improve the quality of the received image and “catch” previously inaccessible channels, it is not necessary to buy a new powerful antenna. The receiving ability of the antenna depends on various external factors, on the shape and design, by changing which you can adjust the image quality.

Antenna location

The quality of the television signal directly depends on the location of the antenna. Concrete walls, metal fences and structures greatly interfere with the passage of the signal, so most often it is located outside the house, on a wall or. If you know where the nearest transmitting tower is, the antenna should be pointed in its direction.

Changing the antenna design

Almost any antenna can be equipped with a special television signal amplifier. It operates on a 220 V network; you can buy the amplifier at most electronics stores. To make the right choice, it is important to know some parameters: noise figure (it should be as low as possible, preferably no more than 2 dB), gain Ku (calculated based on the presence of branches and its length).

Most often, the antenna design is thought out taking into account the standard search for an on-air signal. It can be changed using any metal object that conducts current: wire, cable, balcony dryer, central heating radiators, etc. Aluminum and copper items with a large surface area work best. Metal objects that are not in contact with the antenna, on the contrary, interrupt the signal.

Some antennas require special adjustments before use. You should check whether the correct frequency range is set to receive a particular signal.

Common-mode grating effect

If you take several identical antennas and space them horizontally so that the signal phases in them are the same, you can achieve significant amplification. For example, if a single antenna gives a coefficient of 7 dB, then a double antenna - up to 10 dB, consisting of four parts - up to 12 dB, etc.

Basic rules of the common-mode array: the parts can be purchased or made independently, but must be the same. It is important that the “floors” and “rows” are completely symmetrical, with the same length of lines and cable jumpers. For fixation, frames made of insulating materials, such as wood or plastic, are used.

The TV shows poorly from the antenna - there are two reasons. Inconsistency of devices, bad equipment. The latter concerns the antenna; television receivers cope with the tasks one way or another. However, the problem lies in the amplifier. It must at least be tuned to the desired frequency. Below we will consider typical situations and methods of solving using the simplest methods. The simple way is to buy a satellite dish and install it. Alternatively, stop watching TV, the Internet is much more fun!

Cable problems

It sounds funny, but the first thing you should do is check the cable. There are several requirements that must be observed:

• Firstly, the characteristic impedance of a television cable is 75 ohms. Deviations in magnitude provoke reflection of part of the power in the path, which will inevitably lead to losses. Coordination methods have been invented, using which it is possible to use a cable of a different impedance. Let's wait to fence the garden. Devices designed for television broadcasting with a characteristic impedance of 75 Ohms. We take into account the elementary truth when selecting a cable.

• The second tip concerns owners of indoor antennas. A typical picture: a wave channel and a half-wave vibrator with antennae are hanging, and a cable coil lies nearby. First of all, we look at whether the antenna is active or passive. Do you need to turn on the power? If it turns out to be passive, cut off the excess cable and decorate the pantry with a coil. The feeder segment introduces irreparable signal losses. In an antenna receiver, sensitivity strongly depends on the attenuation before the first amplification stage. In our case, it is located inside the TV; the cable to the socket introduces incredible losses. Another thing is the active antenna. The first amplifier stage is located here, the cable length becomes uncritical.
• If the passive antenna is on the roof, it’s a good idea to get hold of the cable characteristics using the Internet. It is logical to see whether the linear losses exceed 0.2 dB. Attenuation is determined by the length of the feeder and the electrical characteristics of the product. Three meters of good cable introduce attenuation equal to one meter of cheap cable. It is recommended to install an amplification antenna and replace the cable. Fortunately, television is inexpensive. Forget the high cost of high-frequency WiFi!

Why do you need an active antenna?

They said that if the antenna is active, the cable length is acceptable, losses should not be considered a critical element. If you cannot get a good wire, the length cannot be reduced, the roof is far away, you need to buy an active antenna. Please note: to install the equipment, you will need permission from the HOA, the owner of the house. There is insanity: they are forced to draw up a special plan for the placement of utilities, pay a fee to a specialized company, and pay a professional technician to carry out the installation. It has to be done according to the rules.

An antenna amplifier will allow you to bypass the limitations imposed on quality and cable length. The power cord will often need to be pulled to the roof. The distance to the TV station is small, the point is simply blocked by houses - we recommend trying to catch the signal using the indoor variety. The TV will show without a common antenna. It is allowed to place the “Cheburashka”, decorating the balcony, even above the suspended ceiling. The path of passage of the reflected beam is mysterious. However, conditions change according to the weather, and reception will deteriorate (or improve). It is recommended to give preference to omnidirectional antennas, which have a lower directivity coefficient and are equipped with an additional external amplifier.

The antennas reveal a significant drawback that has nothing to do with the quality of reception of an individual signal. The sources of the problems are attributed to the multipath effect. An omnidirectional antenna receives from all directions (azimuths). Several rays will hit, the image will begin to double. Over-amplification causes a similar effect. Remove the electrical power and see the result. Reddish snow is removed in the same way. The reason is the same - over-amplification.

Advice! Adjust the equipment to try to achieve the desired performance. Reduce gain. Buy a television attenuator. These will reduce the gain by twenty dB.

An undeniable disadvantage of omnidirectional antennas has been noted: interference sources will act from all directions, sharply reducing the signal-to-noise ratio. This is not critical for digital multiplexes; broadcasting contains error correction codes. Reception of analog television with an antenna with an amplifier is impossible if the noise intensifies above the level of the useful component.

Antenna selection and installation

The antenna itself may not match the received signal, or it may not be installed correctly. Many people know that it is useful to orient a device in space, but not everyone knows how to do it. Television in Russia on UHF is built on horizontal polarization, so misalignment of the half-wave vibrator or wave channel is guaranteed to lead to poor reception. At the same time, the frequency range also shifts, due to which the picture quality further decreases.

You will need to use a level to align the antenna in the correct position. In addition, when receiving from distant TV towers, a simple rule applies. The higher the antenna is positioned, the greater the chance of catching the broadcast. This rule applies to UHF, which is why the MF and HF ranges still remain attractive. Waves at these frequencies bend around the surface of the earth, so you can catch them without even taking the antenna to the roof.

External barriers also contribute; if there is a forest around, the reception will be worse. Waves attenuate when passing through obstacles. In this case, it is recommended to purchase an antenna with an amplifier. The type also plays a role. Full-wave vibrators receive signals much better, but they are difficult to get in a store. A homemade antenna will help. Made from a strand of copper or aluminum cable and installed according to the rules, it will provide better reception than a store-bought one.

We have already told you more than once how to make a narrow-band antenna that is tuned to the channel frequency. In this case, it is also possible to achieve excellent results in simple ways. Eventually, hobbyists are even constructing quarter-wave vibrators for digital receivers. It's just a short piece of wire with a quarter wavelength of shield stripped off at one end. For the first multiplex in Moscow, this is 13.5 cm. A connector is soldered to the other end, which is inserted into the receiver. The quarter-wave vibrator is located horizontally. If necessary, it can be bent at the base for convenient placement. Even such a simple and uncoordinated design produces results in television reception.

Wave channel antenna matching

Beginners are concerned about the question of how to properly match wave channel antennas. The designs are very simple and provide excellent gain. The design is ideal for the UHF, where digital multiplexes are located. First, let's look at signal balancing. The operation will be required if the descent cable is longer than 10 meters. The device is a piece of wire parallel to the feeder, spaced 3–5 cm.

The method is suitable for a wave channel manufactured according to standard rules. The screen of the reduction cable is simply placed on one side of the active vibrator, but on the other side the balancing section of the cable is attached. The length depends on the channel, for example, for the first Moscow multiplex it is 17.6 cm. At its full length, the piece is parallel to the descent cable. How to connect the device:

• The core of the balun is placed on one side of the active vibrator parallel to the core of the reduction cable. The braid of the segment is closed here.
• At a distance of the length of the balun from the active vibrator, the insulation of the reduction cable is stripped. The screens of the parallel wires are closed, and the second end of the segment core is connected here.

The situation is much more complicated with antennas whose characteristic impedance is below 75 Ohms. Then special matching devices are used. The active vibrator can be made T-shaped. The upper part of the loop is extended with additional wire in both directions. The total length is calculated by the formula:

L = (λ/2)*(1 – 0.225/ln(λ/2d)), where

λ – wavelength, m; d is the diameter of the wire, expressed in meters. The height of the loop is equal to one hundredth of λ or slightly less. The width of the loop is selected experimentally, trying to bring the wave impedance closer to 75 Ohms. The dependence graph is “humpbacked”. The maximum is observed at a loop width equal to λ/4.

By designing your own antenna, this method is suitable for the vast majority of radio amateurs and will allow you to produce a device that has the required impedance. Having a drawing in hand, duplicate the design a specified number of times. Be prepared to work hard if your TV shows poorly. Find out the broadcast frequency and make a special antenna.

Signal interference will be minimal in this case. The procedure for constructing wave channels was described. Explore the portal! Let's gather our strength, consider the design of log-periodic antennas, I'm just curious how to do it. The peculiarity of the product is that it catches a wide range of broadcasts. The coverage of the log periodic antenna is amazing.

Every car these days is equipped with a radio, which no driver can do without. Regardless of what media you like to listen to in your car, virtually every driver uses the radio in their car from time to time. But sometimes the radio receiver lets us down, receiving the radio signal poorly. This is of course very annoying. What to do in such a situation and what is the reason for the poor performance of the car radio?

If the radio in your car begins to poorly receive a radio channel, this does not always mean that the radio antenna is to blame. After all, the source of interference can be tall buildings, cell phone towers along the road, and even a solar flare, which can cause electromagnetic radiation.

In most cases, when there is poor reception of radio channels, the reason is precisely external interference, and not a breakdown of the car’s radio equipment.

So don’t rush to contact electricians with complaints about your car’s radio equipment. First you need to find out what is the reason for the bad radio receiver. Here are five ways you can improve the reception of your favorite radio channels.

1) Check the car antenna

If your car is equipped with an external metal antenna, there is always a risk of damage to it, which will lead to deterioration in the quality of radio reception. For example, the external retractable antenna may become damaged (car wash workers often move the antenna to avoid damaging it and then simply forget to retract it again). It can also be damaged by a bird in the parking lot. Or the machine's antenna may be damaged due to ice formation in the winter. Especially during freezing rain, which can easily bend the antenna and even break it completely. Remember that even minor, unnoticeable damage to the external retractable antenna can significantly affect the quality of radio signal reception.

Therefore, at the first sign of a drop in the quality of radio reception of the radio, check the condition of the external car antenna.

It is quite possible that your antenna is simply not extended all the way and therefore radio channels are received with interference. In this case, you only need to extend the antenna according to the vehicle manual.

If your car is equipped with an electric antenna that extends using a button, then due to ice formation, the antenna may not extend completely. In this case, the signal will be received with interference. Unfortunately, on many cars, antennas are usually installed out of the driver's field of vision, and you may simply not notice that the antenna is not fully extended. Therefore, if the radio signal is poorly received, be sure to check the condition of the antenna.

If your antenna is frozen and does not extend, do not try to pull it out of the car body with pliers. This way you can not only damage the antenna housing, but also the electromechanical mechanism that extends it out of the car.

2) Check antenna connections

The most common cause of poor radio reception in a car is a poor connection between the car radio and the antenna connector. The fact is that if the antenna cable has a poor connection to the radio (with radio tuner), then the quality of radio transmission from the antenna to the receiver will be low. As a result, you will hear interference or only radio noise. Unfortunately, over time, body vibration causes many of the vehicle's wire connections to weaken and become susceptible to corrosion from moisture. This also applies to the connectors connecting the radio receiver to the antenna. As a result, the driver begins to experience difficulties in setting up high-quality radio channel reception.

So if you encounter poor-quality sound when listening to the radio in a car, then immediately after checking the antenna for damage, inspect the cable connecting the antenna to the radio. To do this, you need to remove the radio from the car or push it forward from the center console to inspect the rear of the tuner, where the antenna cable connector is located.

If during a visual inspection you do not find any problems with the connector, do not rush to install the radio back. Please note that the cable or connector may have hidden damage. Therefore, turn on any radio channel that has interference and turn up the volume to listen to extraneous noise. Then move the antenna cable (for example, you can move the radio antenna connector). If the connection is reliable and tight, then you should not hear any changes in the sound of the radio channel. If you hear noise, crackling, etc., then most likely either the antenna cable or the connection connector is damaged.

3) Buy a new radio antenna for your car

When checking the connection between the antenna and the radio receiver, you may find that your antenna has signs of rust, dents or even breaks; in this case, without installing a new antenna, you will not be able to return the quality of signal reception to the previous level. Please note that it can damage not only the antenna mast itself, but also its connectors at the point of connection with the cable that goes to the radio tuner in the car's head unit.

Also, many modern cars are now equipped with new types of radio antennas. This type of antenna is a mesh sticker that is glued to the rear or side windows of the car. These flat panel radio antennas have some aesthetic advantages over external metal car antenna masts. Firstly, the mesh antenna is glued inside the car and cannot be damaged at a car wash, by birds in the parking lot or from the formation of ice.

But unfortunately, such flat antennas do not receive the signal very well. Especially in big cities and hilly areas. Also, the main disadvantage of an antenna on glass is the need to purchase a new one if it is damaged on the inside. Moreover, it can be damaged very easily by simply touching the glass with something sharp.

So, despite the new external antenna on the car body, it still has a number of advantages in terms of the quality of radio signal reception.

4) Install a radio signal amplifier in the car

Usually, in the case of poor-quality radio signal reception in a car, radio amplifiers are not very effective. Especially if the reason for the poor quality sound of the radio channel is related to a broken antenna or wear of the antenna cable and connectors. But usually with this type of damage, poor reception of all radio channels is observed.

But sometimes, even with working radio equipment, each driver is faced with uncertain reception of just a few radio channels. What to do in this case? Indeed, the power of the radio signal from all radio stations is different and radio channels can indeed be received differently by our car radio equipment. How, then, can you tune your favorite radio channel to high-quality sound?

In this case, radio amplifiers can come to your aid. But remember that if interference when receiving a radio station is associated with high-rise buildings or terrain features, then a radio signal amplifier will not help you.

5) Change the radio

In general, the radio tuners in the music head units of modern cars, which are installed at the factory, are of sufficient quality for reliable reception of radio channels. But unfortunately, not all radios are created equal. For example, it is not uncommon for even expensive digital audio units, providing incredible high-quality sound from CD/DVD media, to be equipped with a not very high-quality radio tuner. Moreover, low-quality radios are even found in expensive premium cars. Sometimes the quality of radio signal reception in economy class cars is even better than in luxury ones.

So if you have checked all the radio equipment and have not established the cause of poor-quality radio signal reception, then most likely, if you cannot do without the clear sound of radio channels, you will have to change your standard radio to a better one, which has a more advanced radio tuner.

When choosing a radio, pay attention to the brand and its cost. Remember that cheap units will not be able to provide you with high-quality radio reception in your car.

Determining the reasons why the TV cannot pick up channels

The reasons why the TV cannot receive television channels most often lie in incorrect antenna settings or failure of its amplifier. The reasons for the lack of signal in digital television are also most often problems with antennas.

There are always many reasons why TVs don't pick up channels. They can be the most banal - birds damaged the antenna, to problems with satellite or cable television antennas. But in most cases, when suddenly the TV cannot pick up a single channel, the first thing you need to look for is the antenna. To know for sure why channels are not picked up, you should make sure that the TV video and its matrix are working properly. To do this, you need to connect the TV to some video playback device. If the TV has a good image, it means the video processor is working. Therefore, you should look for the reason in the antenna.

Sometimes this happens. An excellent, correctly oriented and mounted dish antenna, for example, Tricolor, there are many channels. But TV does not work well in bad weather (rain, snow) because... the signal disappears. This happens when a house or cottage is in an area of ​​​​uncertain reception, then there are three options to get a more confident signal. This means raising the antenna higher or purchasing an antenna amplifier.
The second reason when the TV does not pick up signals, it happens, lies in a malfunction in the TV, or rather in the TV antenna socket, which can simply break due to burnout of microcircuit parts. But most people will not be able to solve this problem on their own.
There are situations when an antenna is installed on a multi-meter rod, and when connected to a TV, the signal disappears after a few minutes of operation. Almost all channels found by auto-tuning disappear. The reason here may be the power supply, because... if it is not adjustable, it may output 15V instead of 12V and the antenna amplifier will burn out. Therefore, when you buy an antenna amplifier, always ask the seller for its part number and check whether it is suitable for your area. Sellers, as a rule, have a coverage map, which allows them to navigate the amplifier numbers and select them according to the required power. Also, the reason for the disappearance of the signal may be oxidation of the television cable.

If the TV does not pick up channels when setting up and there is no digital television, then there are a number of ways to eliminate this problem or identify mistakes made. The most common reasons when tuning channels on modern TVs, which have a great many functions built into them, are problems associated with the antennas connected to them, such as:
1. Incorrect selection of antenna type.
2. Incorrectly installed structure,
3. No direction vector adjustment to the broadcast station

When TVs do not pick up TV channels, you should use alternative methods to connect the digital frequency, such as satellite set-top boxes or cables. In order to search using a cable, you need to connect wires from cable TV to the connector for connecting TV antennas. In the settings, when you select auto search in the menu, another window appears. When connecting digital TV, we choose not “cable” TV, but “another operator”. Then click on the “Full” item and select the search “digital channels”. We sort the channels using the remote control and put them in convenient positions.
There are still many problems associated with the loss of signals, both television antennas and cable antennas. But many breakdowns or defects can only be fixed by professionals, so you shouldn’t take risks; it’s better to entrust their correction to specialists who have experience, the necessary knowledge and tools.

TV malfunctions

Malfunctions and their possible causes
Can't pick up channels If the TV does not pick up channels, then most likely the tuner is broken. Sometimes there are no channels due to a TV firmware failure and you need to reinstall the software.
Channels are poorly received If the TV does not pick up channels well, most often there is a problem with the antenna. To make sure that the video processor and matrix of the TV are “in order,” connect the TV to a video device (or insert a DVD). If the image is good, then the screen is working properly and the problem should be looked for in the antenna. What to do: Check the antenna or invite a TV technician.
The TV does not show some channels well Most likely, the broadcast system settings are set incorrectly. For check: analog - PAL/SEKAM; digital cable - DVB-C; digital terrestrial - DVB-T. But there may be other reasons for such a malfunction. What to do: Try retuning the desired channels.

A bad TV antenna signal immediately affects the picture quality. And sometimes sound. If you like to watch TV, this can't help but be frustrating. Our technicians will help you fix the problem of poor antenna reception quickly and inexpensively.

Why is there a bad signal on the TV antenna?

Experts identify 5 main reasons why the antenna signal deteriorates.

1. Weak or faulty contacts on the TV antenna connector, tuner, splitters, cable. Try moving a little all the connectors that are within your reach. If the picture changes, the reason has been found.

   You cannot change connections, especially if it is a TV or antenna connector, as there is a chance of completely damaging the socket. Purchasing a new nest is an expensive proposition.

2. Cable. If there are breaks or kinks along its length, this is reflected in the TV picture. A coiled cable creates a source of interference for the indoor antenna, especially if it is nearby. If the antenna is located on the roof, the signal loss in the cable can be significant. In any case, you need a specialist with equipment to repair radio-electronic or satellite systems.

   You should not attempt to repair the cable yourself. The technician will replace the damaged section, cut off the excess length, or recommend measures that will improve reception without replacing the cable. And you don't have to spend a lot of money on it.

3. Amplifier malfunctions. If the antenna serves you for more than 5 years, the amplifier capacitors fail. On Chinese antennas they will need to be replaced even earlier. In addition, if the antenna is passive, the amplifier deteriorates due to constant operation and voltage surges. Weather conditions also have an effect if the antenna is installed outside. What will the master do in this case? He will repair the amplifier if it can be repaired, and replace it with a new one if it cannot be done without it.

   Sometimes a bad TV antenna signal is due to the fact that the amplifier is not powerful enough for your reception area. After measuring the signal quality, the technician will recommend a model that will provide the perfect picture for your TV.

4. Damage to the antenna. This will be visible to the naked eye: the antenna is crooked, tilted down, fallen, the grille is bent. Branches, heavy objects, ice and snow on the antenna are also causes of interference. In some cases, you just need to rotate the antenna correctly and the reception will be perfect. What to do if the TV antenna signal is bad? If before this the antenna received excellent results, and you are able to correct it yourself, go for it. If you need to determine where to install it, call a specialist.
5. External. This includes malfunctions of the TV itself, interference due to buildings, weather, background obstacles, weak signal from the TV tower, and so on. The most the technician can do here is to recommend an antenna or amplifier model that can amplify the signal, or move the antenna to another place where there is no interference.
