According to the decision of the Russian government, from July 1, 2018, our country will completely switch to digital broadcasting. Moreover, by the summer of 2015, analogue broadcasting must be turned off in the 300 km wide border zone in accordance with international agreements. Thus, ensuring reception of a digital terrestrial television signal is an extremely urgent task and many have questions about what antenna for reception DVB- T2 is the most preferred; Is it possible to leave “Polish”; what to prefer - a separate set-top box or a tuner built into the TV, etc. Therefore, it makes sense to take a closer look at issues related to standard digital signal reception DVB-T 2.
Indoor antenna
Even in the case of a rather weak transmitter, if we are talking about distances up to 10 km, reception of a signal that complies with the DVB-T2 standard can be carried out using any, even homemade antenna, which is inserted into the antenna input of a TV or tuner, but in order for the picture to be high quality, better to buy , especially since such devices are quite inexpensive. At such a distance (up to 10 km), you don’t even have to spend much effort setting it up; you can get a stable signal only by approximately pointing the antenna towards the repeater. This is especially true for powerful transmitters operating in all major cities, when even with the help of such a simple antenna installed on a window, it will be possible to ensure stable reception of a digital television signal at a distance of up to 40 km from the repeater, depending on the presence of interference along its path and from the floor.
Antenna - "Crow"
If we are talking about receiving a digital signal at a distance of up to 30 km from a sufficiently powerful transmitter, then we can recommend an external antenna of the “Crow” type, which is relatively inexpensive and does not need to be adjusted exactly in the direction of the repeater. However, over long distances and with low signal strength, it is still better to install a higher-class antenna.
for DVB-T 2
If we are talking about a distance of about 35 km from the transmitter, then an indoor digital terrestrial antenna may be a good choice. TV for receiving DVB - T and DVB - T 2 with built-in amplifier - “ MARGON HOME +5.0”. Distinctive features of this antenna are remote power supply via coaxial cable from DVB receiver - T 2 or an external power supply, as well as the ability to operate in vertical and horizontal polarizations and a fairly low noise level.
Antenna DRHD-2000
An excellent option antennas for reception DVB-T2especially in the case when the receiver is located far from the television tower or signal reflections are observed, etc. is the antenna DRHD -2000, which can also be installed outdoors.
Can it be used to take DVB-T 2 “Polish” television antenna
Basically a signal DVB-T 2 can also be taken for regular, so-called“Polish” antenna, but this is not always possible, and the picture is rarely of high quality.Moreover, such devices will be unreliable if the distance to the TV tower is more than 30 km.
How to make your own simple antenna for DVB-T 2
Many people are interested in whether it can be made antenna for DVB- T2 with your own hands.It turns out you can . If you try to compose instructions, it will look like this:
· measure from the connector and mark 15 cm on the antenna cable;
· cut the cable in the designated place;
· remove 13 cm of outer insulation and braid from the cut edge, so that only the central copper core remains;
· Based on the signal level of the TV or tuner, determine the best position for the antenna pin; to do this, bend it at the antenna input in different directions depending on the polarization of the signal and the direction to the transmitting TV tower.
It is clear that anyone can make such an antenna, but it will work stably only at a distance of up to 30 km, and only if we are talking about a fairly powerful transmitting station. Therefore, since the prices for even the best “factory” antennas are quite low, it is advisable to make your ownantennas for reception DVB-T 2 , most likely, does not make sense.
Today we’ll talk about what kinds of TV antennas for a dacha there are, which one is better to choose, and what to pay attention to.
In principle, the article can be useful not only for summer residents, but also for residents of suburban towns and villages, and perhaps even for city dwellers.
Let's start by breaking down what types of antennas there are.
TV antennas can be divided into several groups depending on various characteristics.
By antenna location
Everything is simple here: depending on where the antenna is located, they can be divided into three types.
Built-in
If you buy for a dacha portable TV with antenna, then this is just such a case. The antenna will simply be mounted into the TV body. Most often it is retractable in the form of one or two telescopic tubes.
Despite all their compactness, previously portable TVs were still quite heavy and not very suitable for daily carrying. Most often, summer residents brought such a TV with a built-in antenna at the beginning of the season, and took it back to the city in the fall.
Now many people use modern portable TVs with an LCD screen or even Car LCD TVs, which are very compact and easy to transport.
Room
Portable TVs are quite small and not very convenient to watch. Therefore, most summer residents try to bring full-fledged televisions to their dacha. Usually this is some old model of TV receiver, which has been replaced by a new device in the city.
If your dacha is not very far from the transmitting antenna, then it is often enough to connect an indoor antenna for the TV.
If the signal is not very strong, then you will need an amplifier for the indoor antenna. The choice of a signal amplifier in some cases may depend on the type of signal being received, but we will talk about this below.
In addition, now quite often a full-fledged TV antenna set-top box, which allows reception even on older TV models.
Outdoor
If the TV station is far from the dacha and the signal is weak, then an outdoor antenna for the TV is practically the only solution.
Such an antenna is most often mounted on the facade or roof of a house, or on a special separate mast. The weaker the signal, the higher the antenna must be mounted to achieve acceptable quality.
Almost all satellite TV antennas also include outdoor ones.
From the antenna to the TV you need to lay a television cable, which is often an impressive length and also contributes to the loss of signal level.
When installing an outdoor antenna, you should remember the need to install lightning protection.
Based on received signals
Analog
TV broadcasting in the outdated analog format will cease in the coming years, but for now it is still relevant. Considering that Many people have old TVs in their dachas., many gardeners receive an analogue television signal. To receive reception, they either need to replace the TV itself.
To receive analogue TV programs you need a meter range antenna (MV antenna). As a rule, these are quite large outdoor antennas or indoor ones with long “mustaches”.
The MV signal travels over fairly long distances, so in areas remote from transmission towers it happens that there is practically no other alternative other than the meter range.
Digital
A digital antenna for a TV is designed for reception in the decimeter range (UHF). In another way it is also called a DVB-T2 antenna. This option is suitable for you if your dacha falls within the DTV broadcast zone, and also your TV supports receiving a signal in digital format, or you have.
If the “digit” is barely caught, then you either need to “shamanize” with amplification and a good antenna, or still receive analog TV and use an MV antenna. Although a good move would be to buy a universal VHF/UHF antenna, and on the spot we will already decide what we will catch.
In areas without DTV(there are fewer and fewer of these every year), All that remains is to buy an MV antenna and catch analog TV, although there is also the option of satellite television.
Active or passive antenna?
If the TV signal in your area is good, then a passive antenna will be enough for you.
In other cases, you need to amplify the signal, and here it arises two solutions. The first is to buy an active antenna for the dacha(that is, an antenna with a built-in amplifier), second - buy a passive antenna and install a separate signal amplifier. Let's try to consider the pros and cons of both options.
In general, I always recommend buying a passive antenna and a separate amplifier, since this option has several advantages:
- the antenna and amplifier can be changed separately from each other if necessary (for example, in the event of a breakdown, when you decide to change the type of signal being received or buy more expensive equipment);
- the amplifier is less susceptible to burning out during a thunderstorm (in an active antenna with a built-in amplifier, I had this happen more than once, when during a thunderstorm an induced electromagnetic pulse burned out the amplifier inside the antenna);
- the amplifier is located in a dry room and there is less chance of moisture from the atmosphere getting into it;
- in a passive antenna there is practically nothing to break (there are pure mechanics), all the electronics (signal amplifier) are in an accessible place (indoors), so if the electronic components of the amplifier burn out, there is no need to make repairs on the roof of the house.
But this option is viable only under one condition: the distance from the antenna to a separate amplifier in the house should not be very large. I’ll explain in more detail here. Since we are dealing with a weak signal level that came to the antenna, then we need to send this weak signal to the TV.
In the case of a passive antenna and a separate amplifier, we first need to bring the weak signal through the cable to the amplifier, and then Every extra meter of cable causes attenuation of an already weak signal. Therefore, this all works only if the antennas are somewhere nearby. For example, an antenna is located on the roof of a house, a cable from it 3-5 meters long goes into the house where the amplifier is immediately located (in the attic or attic, for example). Further, after the amplifier, a good signal without loss of quality can travel along a cable over a long distance to the TV.
If the antenna is located somewhere far from home, then a weak signal travels through a long cable to a separate amplifier with large losses, only in this case I recommend buying an active antenna with a built-in amplifier. Because a weak signal is amplified immediately in the antenna, and then confidently travels along a long cable to the house.
Distance to TV tower
Respectively as you move away from the transmitting station you need to use an external antenna, put it higher and higher, and buy an antenna with better reception characteristics.
In particularly difficult cases it is necessary build a special high mast for the antenna, which is quite difficult and expensive. And in such cases, you need to buy an expensive antenna with an amplifier with maximum quality.
Sometimes buyers are looking for a TV antenna for their dacha at a distance of up to 100 km from the TV tower! Sometimes in such cases it is worth thinking about satellite TV.
I advise you to look at the neighbors around your property, at what height, what antennas are installed and where they are directed.
Choosing a manufacturer
It is difficult to give any advice on this matter. Nowadays there are many different manufacturers of antennas for TVs. There are many foreign and domestic brands. See what is available in your region, pay attention to the workmanship and reviews of other consumers.
Read our and other reviews and comparisons of specific antenna models.
TV antenna price
The price greatly depends on the brand, the material used and the quality of the antenna. There’s no need to be particularly concerned about the high cost. This is justified only in difficult cases when the signal is weak. But in my practice, in typical dacha suburbs in the area of reliable TV signal reception, most often It is enough to buy even an inexpensive antenna to watch TV in the country without any problems.
Antenna reliability
Reliability, of course, depends on the manufacturer and workmanship.Outdoor antennas are susceptible to precipitation, wind, birds, etc. Therefore, when purchasing, it is worth evaluating can the antenna last for several years without loss of quality?.
Look at material of manufacture. Available for sale steel And aluminum antennas. The former are stronger and more resistant to mechanical stress (for example, to breakage or bending during installation, or when exposed to birds, falling ice, etc.). The second ones are lighter, less strong, but they do not rust. Steel antennas must be well painted.
pay attention to antenna assembly mounting elements to each other and the antenna itself to the bracket, how durable everything is.
At the active antenna, inspect the amplifier block for possible moisture ingress(rubber seals, covers, cable exit points).
In the catalog of our online store we always have outdoor antennas for digital terrestrial TV DVB-T2, which are designed to receive digital television signals of the DVB-T2 standard.

Varieties
For high-quality display of DVB-T2 digital terrestrial television, you will need a reliable receiving antenna. This can be an indoor antenna or an external one (outdoor, street), active (with power supplied to the amplifier) or passive.
Outdoor DVB-T2 TV antennas cope with their tasks better than indoor ones. The most commonly used models are log-periodic and wave channel designs. Both options provide reliable reception of an on-air digital signal.
For a medium-level signal, antennas without an amplifier are sufficient. Especially when installing them at heights and in open areas. The only condition: high positioning accuracy on the TV tower. If reception from a remote transmitter is poor, an amplifier is a necessity.
As for passive antennas, the better, more reliable and more powerful the design of the model, the better reception it provides.
Features of choice
The antenna that is required to receive DVB-T2 digital terrestrial television signals can be passive or active (with power supplied to it).
When choosing an antenna for DVB-T2 TV, you should take into account the distance to the nearest repeater, the terrain, the presence of natural and artificial interference, both physical and electrical, including power lines.
Plus installation and power supply features for active-type models. Only by comparing all these factors can you choose the appropriate type and model of antenna.

Analogue television is becoming a thing of the past, so to maintain the ability to watch TV shows, a transition to DVB-T2 television broadcasting is required. To do this, you need to use a specialized antenna, which can be made with your own hands from available materials, which is what I will do.
Required materials and tools
To make an antenna you will need:- a piece of television coaxial cable 20 cm;
- HF connector (transition from F type connector to TV plug);
- F type connector.
Determining the broadcast frequency in the city
Before you begin assembling the antenna, you must first find out the frequency of digital television broadcasting in the region. Since I live in Russia, for this I go to the official website of digital television of the Russian Federation. On it I look for the “ ” tab and select my locality. On the map that opens, you need to find the nearest repeater and click on it with the cursor.
In the window that appears, click on the “more details” link. As a result, detailed information on the digital television parameters of this repeater will open. In my case, there are two packages of TV channels RTRS-1 and RTRS-2. I'm interested in the direct frequency in megahertz. Available packages are broadcast at 754 and 778 MHz.
Based on these data, it is necessary to calculate the actual length of the working part of the antenna in centimeters. A simple formula is used for this. It is necessary to divide 7500 for each frequency. In my case, 7500/754=9.94 cm and 7500/778=9.6 cm.
Thus, in order for the antenna to be able to normally receive both frequencies, it will be enough to make it 10 cm long. Naturally, residents of other cities will get a different result, but regardless of this, the immediate manufacturing process is completely identical.
Direct production
To make an antenna you don’t have to buy anything, since in most cases all the necessary materials are already available, as they were used to ensure the operation of analog television. First you need to take a piece of coaxial cable about 20 cm long. One end of it is stripped to secure the F connector. To do this, remove the top insulation approximately 3 cm from the edge to expose the cable shield. The bare winding, together with the protruding foil, is bent to the opposite end from the working edge.After this, stepping back 3 mm from the resulting cut edge of the top insulation, you need to cut the cable to the central copper core. After this, the F type connector is screwed on. The copper core of the wire protruding in its center is cut so that its tail extends beyond the connector by no more than 1 cm.
Now the RF connector is screwed onto the F connector, which is then connected to the TV plug.
Having stepped back about 3-4 cm from the edge of the F connector, in the opposite direction, you need to put a mark on the coaxial cable. As much as was calculated by the formula is measured from it, and the wire is cut. I cut after 10 cm.
According to the previously set mark, you need to cut through the top insulation to the screen winding. It is removed, revealing the inner insulating layer.
The existing screen winding is removed because it will not be needed, as it creates a barrier to signal pickup. The antenna itself is bent at 90 degrees at the step between single and double insulation.
Now the antenna can be screwed directly into the connector on the TV or set-top box if DVB-T2 is not supported by it.
If the repeater is close enough, the signal is picked up clearly enough to watch TV without interference. If the picture ripples and slows down, then the antenna will have to be taken outside. To do this, use a coaxial cable of the required length, and a couple of additional adapters.
Setting up and searching for channels
Setting up the TV is very simple. Everything happens automatically. We choose to search for just digital or digital and analogue channels.We start the search and wait for a while.
We caught about a dozen channels.
Feasibility of using an antenna
Making an antenna will only help if the TV supports the DVB-T2 digital television reception function. Outdated models do not have this capability, so they require the purchase of a specialized set-top box, which usually already comes with an antenna.It is also important to check for a nearby repeater before production. The effective range of such an antenna cannot exceed 6-15 km. This is only subject to good visibility of the tower without high-rise buildings and other obstacles located in the path of the waves. If the distance is greater, then the use of an additional amplifier will be required, which ultimately also comes down to the purchase of a specialized TV set-top box.
An indoor TV antenna is a simple device that receives a television signal. It is used in a building and installed on a television receiver, to which it is connected with a special coaxial cable. This type of receiving device differs from other types of antennas in its simplicity of design and low cost.
Advantages of a home wave receiver:
- low price;
- ease of installation and connection;
- compact dimensions;
- possibility of free movement if necessary.
Main disadvantages:
- each channel has to be configured separately;
- works only in the immediate vicinity of the broadcaster;
- sensitive to obstacles in the form of buildings, plants, precipitation, and so on;
- does not provide good quality signal transmission without interference.
Reception efficiency and signal quality depend on the following conditions:
- at what distance from the repeater is the indoor antenna located. A repeater is a powerful antenna that not only receives a signal, but also broadcasts or transmits it into space. A repeater is also called a television tower. A separate transceiver is installed in each region or locality. The farther the wave receiver is from the tower, the worse it will pick up the signal;
- on the type of wave receiver and the presence of additional devices that amplify the signal;
- at what height level is the device located relative to the television tower;
- on the presence of barriers between the tower and the antenna and their features. This refers to buildings and their height, landscape, vegetation;
- from the location of the wave receiver in the building. Most often, they are installed on the TV itself or on a nearby window, which improves the characteristics of the received signal.
Indoor antennas: main types and description
Wave receivers used in the building are divided into several types according to their design features and the maximum wavelength that they can pick up.
- A meter antenna is the simplest representative of home receivers. Capable of picking up a wave signal that is in the meter range. It is a structure consisting of a stand that houses a transformer with two movable “whiskers” in the form of thin telescopic rods, and a cable connected to the TV. This design for signal reception will show good results only if it is installed at the closest distance from the broadcasting tower. Meter wave receivers are not popular among buyers, since modern TV channels have almost completely switched to the digital broadcast format. There are about five Russian channels left in the meter range.
- A decimeter or loop antenna is a type of receiver that operates in the decimeter wavelength range. It is a device consisting of a base, an open frame contour and a cable for connecting to a set-top box or TV. This type of receiver is capable of providing a good signal at a distance of up to 30 km from the broadcaster.
- A hybrid receiver (all-wave) is a type of device whose design allows it to receive both meter and decimeter waves of a television signal. Convenience lies in the ability to switch between ranges if necessary.
- A passive wave receiver is a conventional device for capturing a signal without additional options to enhance the sensitivity and efficiency of wave perception.
- An active antenna for a TV is a device that includes a special amplifier to improve the quality of the received signal. Receivers with an amplifier are used at a great distance from the broadcaster's tower or in cases where the signal needs to be divided into several televisions. Because when separated, the signal quality deteriorates.
The most widespread is the home TV antenna, which is capable of picking up digital television signals. Therefore, we will consider this type of wave receiver in more detail.

Home digital antenna: features of choice
Digital indoor TV antennas are a type of wave receivers that receive signals from UHF waves. In another way, this type of antenna is called DVB/T2 format receivers. That is, in essence these are the same decimeter antennas.
In order for the TV to receive and convert a digital television signal, the installation of a special DVB/T2 receiver is required. Some TV models already have a built-in receiver that will receive digital television data.
How to choose an antenna for a TV that can receive a digital signal?
- First, determine whether the digital broadcasting format is supported in a given region;
- check the distance from the repeater to the installation site of the wave receiver. Such information can be found on special websites or using a search engine;
- The markings on the packaging usually indicate the type of receiver for various television broadcast formats. If it is indicated that the antenna is UHF type for receiving an over-the-air signal, this does not mean that for DVB/T2 it is necessary to buy a separate wave receiver. Since any UHF wave receiver can pick up a digital television signal if it has a built-in or external receiver;
- the presence of a cable, stand for installation or mounts for hanging the receiver.
Therefore, we will consider some models, most of which had better performance under different installation conditions.
- Model of a wave receiver with a Mini Digital amplifier from the Saratov electromechanical plant "Remo". The device is a frame with small suction cups for mounting on a window and a stand in the form of a small box. Installation requires a power connection to the amplifier. The kit also includes a three-meter cable for connecting to a TV. Mini Digital is designed to receive UHF signals, and therefore DVB/T
- Sirius series 2.0. — home antenna on a stand without an amplifier. Designed to receive decimeter waves. The coverage area declared by the manufacturer is up to 45 km.
- Chinese wave receiver Denn DAA series 238. The model is equipped with an amplifier and is capable of receiving up to 20 television channels plus about three radio channel signals.
What to do if the indoor antenna does not “catch”
Poor quality of the received signal does not always mean that the receiver design is ineffective. Before changing the purchased wave receiver, you need to try some actions. Perhaps they will help improve the quality of the received signal:
- Change the height of the mustache or the device itself. Some interference may not allow the signal to pass through at the level at which the antenna is installed. It happens that changing the installation height on the TV or on the window leads to an improvement in the signal.
- If the antenna is installed on a plastic window, then the metal-plastic structure of the window itself can serve as an interference. In this case, the antenna can be installed on an additional stand or mounted on glass.
- Change the angle of rotation of the entire device or its moving parts. Sometimes placing the antenna perpendicular to the signal source gives a noticeable improvement in quality.
- It is necessary to change the position of the device or its angle relative to the repeater smoothly, since it happens that even a shift of 5 millimeters affects the signal.
If all the necessary settings have been made, but the signal is still not “caught”, or it turns out that the distance to the broadcast tower is too great, in this case an outdoor TV antenna will be a good alternative.
What types of outdoor antennas are there?
The design of such devices is more complex, but, like indoor ones, they are designed to receive an over-the-air television signal. There are meter, UHF and DVB/T2. To install outdoor wave receivers, you will need a special coaxial cable with reinforced insulation and a sufficient height level. The further away the tower is, the higher you need to install such an antenna.
It is better to install a satellite dish in places farthest from television towers. A parabolic antenna, or “dish,” is designed to receive television and radio signals transmitted by a satellite. To operate this type of antenna, you need a special tuner and a coaxial cable. The dimensions of the dish are selected depending on the region where it will be installed, as well as on the operating range of the radio frequency signal of the satellite to which the device will be tuned.
In conclusion, I would like to note that purchasing an expensive antenna does not guarantee excellent quality of the received signal. Since, in addition to the characteristics of the receiving device itself, environmental factors are no less important, which have a significant impact on the attenuation, reflection and transmission of waves in space. Therefore, it is impossible to unambiguously call any particular antenna model good or bad. In this case, when purchasing, you must, first of all, be based on the characteristics of the area where the device will be installed.
