What determines the quality of a TV signal?
There are several factors affecting the quality of TV signal reception and most of them are related to the installation or quality of the antenna:
- Your cottage is located too far from the TV signal transmitting repeater, so the received signal is too weak. To strengthen the long-distance signal, you need to select a digital TV antenna with an amplifier.
- There are obstacles between the antenna and the transmitting station. These can be natural obstacles: mountains, lowlands, close-growing trees, as well as high-rise buildings. In this case, the antenna for digital TV in a private home should be raised as high as possible.
- A large distance to the transmitting station, as well as low quality antenna cable. The recommended distance to the TV is no more than 5 meters.
- The antenna for digital TV is not installed in the direction of the transmitted signal. In this case, look at the direction of your neighbors' antenna.
In addition, the quality of the received signal is also affected by the number of connected TVs. If there is only one, then you can do without an amplifier. But when there are several, then an antenna amplifier is simply necessary.
Operating principle
Knowing the principle by which television broadcasting works makes it clear how to choose an antenna for your dacha. However, the consumer does not need to go into technical details. It is enough to have only a general understanding of the types of TV transmission technologies existing today. These are primarily the following 4 varieties:
- Digital (analog) . Allows you to watch about 2 dozen free channels.
- Satellite . It uses a paid connection.
- Internet TV . Distributed through a specific Internet provider. The catalog contains up to several hundred channels.
- Cable . As a rule, the list of channels always includes several federal ones.
Installing an antenna in a private home is only necessary for the first two options. In the first case, broadcasting is carried out through a repeater, and reception is carried out by the user’s device. In this case, electromagnetic waves of a given frequency propagate freely in the atmosphere within the covered area, arrive at the receiver, are converted and display a picture on the screen.

Broadcasting from a satellite occurs in a similar way. The only difference is in the reception technology, signal processing and frequency, as well as the design and features of the antenna. The advantage of the second method is that the strength of the received signal is independent of the distance to a large city. If in the first option its power weakens in inverse proportion to the square of the distance, then in the second it is unchanged - since the repeater in space is always located at approximately the same distance - regardless of the location of the receiver over the entire area of the globe.
Note! Cable and IP television do not require installation of an antenna in the country house, or in any other place. However, pulling the cable to a remote country location is unprofitable and sometimes simply technically impossible. The internet signal may also be very weak. Therefore, these two technologies still remain the prerogative of large cities.

What types of antennas are there for digital TV?
To receive a digital dvb t2 signal at the dacha, the following types of television antennas are available:
- Indoor . They are used if the repeater is located nearby. As options, room units with a signal amplifier are available.
- External passive . Installed outdoors to receive a digital signal and transmit it via cable to the receiver. Sometimes a filter is installed on it to eliminate reception interference.
- Outdoor active . An antenna with a built-in amplifier is used to receive a weak signal. It receives a UHF signal, amplifies it and transmits it further to the TV.
Directionality is very important for the quality of digital television reception. The clarity of the resulting image depends on this. Based on this feature, devices are divided into narrow-directional and broad-directional.
In a country house or country house, it is better to install active antennas for digital television with a signal amplifier, since due to the long distance to the TV tower, the signal strength is weak.
Briefly about the main thing
The antenna on the roof of the house is installed on a mast or a special bracket. The method depends on the type of receiving device - satellite or UHF antenna. However, in accordance with fire regulations, it is prohibited to install them on ventilation shafts, chimneys, or gas pipes. The location for the device is selected so that there are no bulky structures nearby.
The antenna can be installed on one of the roof slopes, a ridge, or near the edge of a flat roof. When using a mast, a metal base frame is prepared in advance. For reliable fixation of the vertical support, stretch marks are additionally used. The cable is fixed on the ridge and slope of the roof to the window through which it is introduced into the house.

What antenna is needed for digital TV in the country
The quality of signal reception depends on the type of antenna you have installed for your dacha. The country is switching to digital broadcasting, and it is necessary to install devices capable of receiving digital broadcasts. True, some stations will continue to broadcast in the meter range and to view them you need a different type of television antenna. A good option is to install an all-wave antenna that can receive both digital and analog signals.
The dacha village is located far from the RTRS transmitting center and using an indoor antenna will not help receive high-quality signals. But if the signal source is located at a distance of up to 50 km, and the transmitter power is 5 kW, then in the absence of obstacles in the form of hills, you can try an indoor antenna. It just needs to be located on the second floor and above.
But it is better to install an external antenna for the TV for reliable reception. In this case, there are two solutions for a country house. One of them is a passive television antenna. If the cottage is located in an area of weak signal, then a separate amplifier is installed. Another option is to choose an antenna with a built-in amplifier.
In the first option, the amplifier is located in a country house and is not affected by precipitation, damage during a thunderstorm or icing. The external antenna receives a weak signal, and while it travels along the cable, it gradually fades. Therefore, the cable length before installing the amplifier is 3-5 meters.
If the cable length is long, then it is better to use an active outdoor antenna with a built-in signal amplifier. The resulting weak signal is immediately amplified in the antenna and then transmitted via cable to the TV. If the dacha is located at a distance of up to 100 km, then you should think about installing a satellite TV antenna.
Installation on a metal mast
As a support for the antenna device that receives on-air programs in digital format, rolled metal pipes are used, the diameter of which can range from 32 to 50 mm. If the roof is made of soft material, the mast can be installed from the ground.

When performing such work, specialists observe the following rules:
- The mast is mounted next to the wall of the building.
In this case, the metal pipe should not touch the eaves overhang - the roof canopy.
- At the top of the pole mast, 3-4 elements are fixed in the form of loops for the tensioning device.
For this purpose, flanges with holes can be used. They are put on the pipe and placed at the same distance from each other. Such elements are fixed using limiters. They are placed directly on the mast under the hinges.
Limiters make it possible not to tightly fasten the pipe in the brace elements. Thanks to this design, the mast can be rotated while setting up the UHF antenna.
- Stretches are performed using galvanized wire.
Its cross-section is from 3 to 4 mm. On the ground, guy wires are attached to anchors located in concrete. Instead, other durable roof elements can be used.
- A steel coin is placed under the pipe.
This element has a pin onto which the mast is placed. The nickel prevents the pipe from subsiding into the soil.

Do I need to use an antenna amplifier?
At dachas located far from transmitting stations, in order to receive a clear signal, it is important that the antenna be installed at a high altitude. But sometimes this is not enough; the image quality leaves much to be desired. In this case, a received signal amplifier is installed.
The simplest solution is to install a digital antenna with a built-in amplifier. The built-in amplifier is a device that amplifies the weak signal received by the antenna and transmits it further to the receiver. The gain depends on the design of the device and is approximately 30-40 dB.
The amplifier requires a power supply to operate, usually 5 volts. Food is served in different ways:
If you have a digital set-top box, then power can be supplied to the amplifier directly through the antenna cable. In the set-top box menu we find the item “turn on antenna power”, and that’s enough.
If your TV without a set-top box receives a digital signal, then use a special adapter that connects to the TV via a USB port or install an antenna powered via USB.
You can also use a power supply by connecting it to a regular electrical network.
When you have reliable reception without an amplifier, then you don’t need to use it, since due to the signal level being too high, the receiver may not show anything at all. There may also be interference and noise from extraneous signals.
Installation of a dish for receiving satellite television
The process of installing a satellite dish is easier compared to installing a UHF antenna. This is facilitated by the presence of fasteners included in the mirror kit. Therefore, there is no need to purchase an additional base for a satellite dish. Most likely, you won’t have to order it from a specialized company either.
The rooftop installation process involves attaching a factory-made satellite dish base to the roof. Specialists perform this work in the same way as installing a UHF antenna on a mast. The only difference is that in this case no stretch marks are used. After all, the mirror is installed low, since the height does not matter for a satellite dish. To receive a good signal from the satellite, you need to set the mirror in the correct direction.
If the installation is carried out using a vertical support in the form of a pipe, then, depending on its height, spacers or the same braces can be additionally used. In general, the method of installing a satellite dish is chosen individually in each specific case.
Rules for installing an antenna for digital TV
To get a high-quality image at your dacha, it is very important to correctly install the antenna for digital TV. First of all, this is the installation height; reliable reception is ensured by an antenna installed as high as possible. Installation and installation is carried out on the roof or wall of the house, or on a high mast approximately 10 m high.
The second factor is the exact orientation of the device to the transmitting station. This installation can be done by rotating the mast, achieving a better display, or by analogy with the direction of the neighbors’ antenna. We should not forget about safety; a high mast attracts lightning during a thunderstorm, so it is imperative to install lightning protection.
The TV antenna mount for digital TV must ensure strength in case of sudden gusts of wind. It is not recommended to install the device near a high-voltage line, as interference and transmission distortion will occur.
When choosing the type of antenna, carefully select and prepare the site for installation. If you have the opportunity to talk to your dacha neighbors, consult with specialists. There is no need to rush and make hasty decisions in this matter, otherwise you may waste time and money and not get a high-quality image.
Antenna Grounding
Most experts agree that grounding the antenna at the dacha is necessary. This will reduce the electrical voltage to a safe level and protect the equipment from fire when struck by lightning. The down conductors are connected to grounding devices, and the lightning discharge is redirected to the ground.
On grounded equipment, the amount of interference is reduced, the image and sound become better.
Grounding options:
- The antenna reduction plug is plugged into the plug socket. The wire is soldered to the socket, connecting to ground.
- The two-wire cord is soldered to the core and sheath of the drop wire. The cord cores are stripped of insulation, soldered and connected to the ground wire.
Grounding can be traditional or internal. With traditional grounding, lightning rods and down conductors are installed. Internal grounding involves carrying out work to protect electrical wiring in the country house.
Opponents of grounding argue that the antenna will be hit by all lightning strikes that occur nearby. This risks burning out the board and amplifier, which will need to be replaced. If the antenna is located below the power line, then it does not need to be grounded. Lightning always strikes the highest grounded point.
Every summer resident asks the question of which antenna to buy for his country house. Today the market offers a wide selection of equipment that differs in operating principle, power, size, weight and cost. The choice of antenna should be based on the terrain and the distance of the television tower. With the correct selection and installation of equipment, the TV will delight summer residents with high-quality image and sound in any weather.
