City residents rarely face such a problem as poor television connection - cable or Internet TV provides a large selection of channels and high-quality picture. But far from the city, summer residents have to be content with a couple of channels and a frankly weak signal.
The outdated analog format is being replaced by digital television in the country. It has a lot of advantages:
- More channels.
- High resistance to interference.
- The user receives better quality picture and sound.
- Recording of the program and subtitles are available.
- Even if the transmission has already started, you can start it from the beginning.
Of the minuses:
- Weak signal in a thunderstorm.
- If the signal is very weak, the picture will turn into “squares”.
There are 4 ways to transmit a signal:
- Cable.
- Internet TV.
- Ethereal.
- Satellite.
The first two methods are practically inaccessible at the dacha, so you have to choose between terrestrial and satellite broadcasting.
Content
Almost all residents of cities, regardless of their size, receive a high-quality TV signal via cable. However, at a great distance from a populated area, the quality of the signal drops significantly, and cable television is generally unavailable. This problem is always relevant for owners of summer cottages. Reception of digital TV in the country depends on many factors that need to be taken into account when choosing a suitable antenna.
Reasons for poor image
In our country, terrestrial television is at the stage of active development. This explains the use of analogue TV in certain localities. You need to understand that the large distance of the cottage from the transmitting tower increases the noise level, reducing the quality of the signal. The use of a digital signal will allow many summer residents to watch TV shows. It is worthwhile to figure out in advance how to connect digital television and the Internet at the dacha in order to select and install suitable equipment on the site.
TV via Internet
Is it possible to watch TV programs using the Internet? After all, the development of modern means of communication allows you to enter the World Wide Web from almost any locality in our country.
Can. But it's not that simple. The flow of information transmitted when watching a video is very large. This can be provided either by a cable connection or by good quality mobile communications (3G or 4G). Moreover, only cable will provide truly unlimited access: mobile operators’ unlimited tariffs still have restrictions that make it almost impossible to watch TV programs (for example, the data transfer speed sharply decreases after exceeding a certain limit). The included traffic package may be enough only for occasional viewing: you won’t be able to watch programs for hours with mobile access.

Moreover, even if the connection is excellent and there are no restrictions, “explaining” to a regular TV how to show your favorite series is not the easiest task. Only smart TVs (Smart TV) “are able” to work with the Internet. Older models will again have to be connected through their corresponding, separately purchased set-top box. Most major television channels broadcast from their websites, which you can connect to using Smart TV applications. As an option, you can watch TV shows directly from websites not on the TV, but on the computer, or use the TV as its monitor.
The cost of such television is low, but it will not be possible to calculate it separately, since it will be included in the subscription fee for all Internet services.
The main advantages of digital television
A digital television signal has a number of positive characteristics, including the following:
- increased resistance of transmission channels to interference;
- reduction in transmitter power;
- a significant increase in the number of television channels;
- creation of systems capable of providing the owner with an image of increased clarity;
- the possibility of influencing the program;
- increased functionality;
- the presence of an archive of programs and the ability to record.
Digital television has increased resistance to various interferences and noise. This can easily be explained by redundant signal encoding. TV in a country house, obtained using a digital tuner, will have high picture and sound quality even in conditions of strong interference.

Types of digital television
Digital television can be divided into the following groups:
- cable TV DVB C;
- terrestrial TV DVB T2;
- satellite TV DVB S;
- Internet TV IP TV.
Cable and IP television are not suitable for dacha use; it is extremely rare to connect them at the dacha. The remaining 2 varieties can often be found outside the city today. Satellite DTV is chosen for areas located at a very large distance from the transmitting tower. This indicates the unavailability of other types of television. The distribution of digital terrestrial TV has become the optimal solution for residents of suburban areas and summer residents.
From mobile operators
Large mobile operators have also acquired their own television broadcasting. By connecting to this service, you can get access to a fairly large set of television channels (priced from 150 rubles per month). The only problem is that without additional actions or devices, you can only watch them on mobile devices - smartphones or tablets. The ability to display an image on your favorite TV must be clarified in detail from each operator.
Some operators offer connection to their own satellite system. But this should be considered not as mobile, but as full-fledged satellite TV.
By the way
Television channels may not have the legal rights to broadcast certain programs, such as a movie or a specific match, over the open Internet. Therefore, the TV program on the site sometimes differs from that on terrestrial or satellite TV, which becomes an unpleasant surprise for viewers.

How to connect to terrestrial DTV
For proper connection, each future subscriber needs to understand how to quickly connect digital television in a private home. To do this, you need to find out the DTV coverage area. The quality of the picture, as well as the availability of the signal in the dacha area, depends on this factor.
Contacting neighbors in the country is considered the easiest way to obtain the necessary information. By sharing their experience, they will be able to talk about what signal their indoor antenna receives in the village. If this is not possible, other methods should be used. This will help simplify the task and provide television to the dacha in the desired format.
Necessary equipment for digital TV at the dacha
The easiest way to get an optimally functioning system is to contact companies that offer a ready-made set of equipment designed for installation at a certain distance from the base station. But you can choose it yourself. For digital television in the country you need:
- UHF receiving antenna operating on ultrashort waves DVB T2;
- an amplifier if the quality of the passive antenna signal does not allow you to get a good image;
- stand-alone tuner, digital TV set-top box.
Important!
You can do without a set-top box if you use a modern TV that works with a DVB T2 signal. Such models are common and already very affordable. Individual elements of the system must be selected very carefully.
Antenna selection
The choice of receiving antenna should be approached very carefully. These devices can be passive or active, equipped with amplifiers. There are directional and non-directional models. In general, the selection recommendations look like this.
- At a distance to the station within 10 km, indoor passive models perform well. They are inexpensive, lightweight, and easy to install.
- For distances up to 20 km, choose active internal antennas. They show excellent results in the countryside, where there are not many obstacles in the signal path. Typically, devices of this class are non-directional and equipped with powerful amplifiers.
- A range of 30 km is the limit for the reliable reception zone. Active omnidirectional outdoor antennas work well here. There are successful indoor models.
- In cases where terrain or other conditions limit the free passage of the signal, it is recommended to install directional outdoor antennas. They can be passive or active.
- At a distance to the station of more than 30 km, highly directional antennas should be selected. These are quite large devices. Some of them allow you to receive a stable signal at a distance of 100 km or more.
Some attention should be paid to the supply voltage of the receiving device . 220V, on the one hand, is a convenient technical solution. The user just needs to lay the cable line and plug the plug into the socket. However, such voltage is dangerous. Electric shock can occur when inspecting the antenna, when the cable breaks and falls to the ground, or from short circuits due to worn insulation.
Twelve-volt options are safe. However, not only do you have to have a separate outlet in your home, you also have to put up with some fire hazards. The main voltage conversion unit gets hot and can catch fire or explode, for example, if the amplifier malfunctions.
The most convenient antenna options are those with 5V power supply. Most of them can be plugged into the USB port of a TV or set-top box. However, this means low power of the amplifier and the solution is attractive only when considering models aimed at installation in an area of reliable reception.
A separate class of devices are antennas that receive power via a signal cable. However, in the safest use case, they should be connected to receivers that have the appropriate functionality.
Advice! If you do not have sufficient knowledge to choose a model yourself, it is better to seek help from specialists. Or carefully question neighbors who already have a high-quality technical solution that works.
Selecting a console
You need to choose a console for two reasons.
- Set of ports. Among them there should be one that is supported by the TV.
- Provider. Today, many companies offer an expanded version of terrestrial digital television. The list of channels includes free federal and paid packages. Its composition depends on the provider's offers. To view paid channels, the user will need a digital television card and a set-top box that supports working with such a medium.
Advice! If you want to get more opportunities and take advantage of the offer of a CETV provider, for example, Rostelecom, you don’t have to worry. The operator himself will offer a set of equipment for viewing your favorite programs in the country.
Amplifier
Receiving antenna amplifiers and intermediate cable network amplifiers perform two roles - raising the signal level and compensating for its losses . In addition, they allow you to build a safe and stable system.
Using an external active amplifier with a passive antenna, you can get high reliability, protection from thunderstorms, birds, bad weather and other negative factors. In addition, selecting a model will provide the necessary signal parameters.
Intermediate passive amplifiers are installed on cable network lines inside the house. Such devices do not require external power. Their task is reduced to compensating for wave losses during transmission. With long cable lines, intermediate signal amplifiers will not be superfluous.
Coverage area
The coverage area of the signal emanating from the transmitting tower extends to 30-50 km. This indicator depends on the characteristics of the landscape. Each region has one or more operators providing digital television services to the population.
You can find out the coverage area like this:
- go to the official website of the service provider company and study the digital signal coverage map;
- call the subscriber department and, with the help of the operator, clarify whether it is possible to connect to the DTV network in a specific area;
- send an email to the relevant department of the operator and wait for a response.
If a summer cottage falls within the coverage area of a digital signal, the user must purchase suitable equipment for organizing television in a country house.

Digital antenna for a summer residence
The proposed antennas of this format can be divided into the following varieties:
- indoor;
- external;
- universal type.
If a country house is located in close proximity to the station, the connected subscriber can easily use an indoor-type antenna. A distinctive detail of this design is the increased length of the mustache.
A large distance from the transmitting station requires the installation of an external antenna. For installation, you need to choose the highest point, which is located on the roof or a separate mast. By installing the antenna in this way, the user will receive high quality pictures when connecting to digital TV.
Universal antennas allow you to connect to analog TV and digital signals. This is easily explained by the presence of two antennas in one design. Such equipment can easily provide a signal to several televisions at once, one of which can be connected and configured to receive an analog TV signal, and the other will have a connection to digital TV. This makes such an antenna a universal device.
Which amplifier to buy for a country antenna
The device is designed to maintain a normal pulse level after it passes through the cable with further decryption and delivery of a high-quality image to the screen. The operation of the amplifier is useful only when several conditions are met:
- a pulse with sufficient power is supplied to the TV;
- an extended cable runs from the TV to the decoder;
- the equipment and wire are functioning properly.
In other cases, the use of an “amplifier” is not justified; it will not be useful or will create interference. On satellite equipment it will only increase the noise level in the cable. As a result, on the screen, in addition to a high-quality picture, unwanted displays in the form of stripes and squares will appear.
Operating amplifiers in the T2-DVB configuration, unnecessarily, is fraught with the appearance of an incorrect picture in the form of channels superimposed on each other. In this case, the low quality of the weak impulse is solved by searching for the cause in the quality of installation and reception of the set-top box.
When operating the T2-DVB amplifier, the power parameter is not added to the original indicators, but is increased to the calculated nominal value. Connecting a device with a coefficient lower than that of the received signal does not bring the desired result.
Rules for amplifying VDB digital TV for a summer residence
The image quality after amplification depends simultaneously on several parameters:
- initial indicator of the received pulse;
- cable length;
- gain.
In this case, stable and reliable reception will be ensured only with amplification with tolerances up and down. In this regard, there is no unified system of theoretical calculations for correct amplification and connection. The optimal result is achieved in a practical way, which will show how justified the use of an amplifier is in a particular case.
Algorithm for amplifying digital TV:
- Select the connection location. Since the cable “eats” power, it is advisable to connect the device directly behind the receiver. If a distribution box is used, the amplifier is mounted in front of it.
- Power is selected based on connectivity. With minimal energy consumption and operation of modern equipment, it is better to immediately purchase a digital active antenna.
- Select the gain factor. Usually a gain parameter of 32 dB is sufficient.
- If after turning on the TV there is a clear picture and sound, the amplifier is selected correctly.
The wire cable is connected and separated exclusively at right angles. This minimizes noise within the wire due to direct reflection from the conductor.
Digital set-top box
The variety of TV set-top box models on the market allows each user to choose the best option for their dacha. The main condition that must be taken into account when choosing this equipment is the ability to support the DVB T2 broadcast format. The buyer chooses the remaining parameters at his own discretion. It must be remembered that budget-class tuners perfectly receive digital signals in the DTV coverage area. The cost directly depends on the number of additional options and capabilities of the set-top box. Such equipment is easy to set up and easy to use.
