TV antennas: What happens and how to choose?

TV antenna It is an integral part of the TV, it improves the quality of TV signal reception. The design of the device determines whether it will be an analog television, digital or satellite signal. At the moment, analog and digital television are considered the most common. But how to choose the wrong antenna and pay attention to first?

Peculiarities

TV antenna – very common device, almost all TVs will not be able to fully work without it. Exceptions are those devices that are connected to cable television. Receivers for TV differ by type(“Wave Channel”, a logoeriodic antenna, phased lattices and others), enhancing signal reception coverage.

Scope of working frequencies differ and divided into Rangean, single-channel and overgrowth antennas. Very good signal catch Single-channel devices, but, unfortunately, they take only one channel. Range antennas Most often equipped with multi-storey and public buildings, these devices have large dimensions and a complex structural composition. Most common Mental receivers.

Dimensions of the receiver are interconnected with a wavelength. The high frequency of receiving the signal signals the short wave and small size of the vibrator, directors and the device reflector. Focusing diagram directly affects the gain factor. To receive digital television broadcasting, in addition to the antenna, it is necessary that the TV receiver supported the DVB-T2 standard or a special receiver.

There are also a few features that need to be considered.

  1. The reception of the signal is carried out only in the decimeter range – the devices operating in the meter range are not suitable for “figures”.
  2. The presence of an amplifier must. Amplifier can be built-in or bought separately. The device is a small block with autonomous power, an antenna signal goes to the input, and the output is connected to the TV. Image quality improves.
  3. The receiver must be sharply directed to prevent unnecessary interference in the signal.
  4. When the signal is loosening, install the equipment with filters to protect against LTE signals.

Number of televisions Also determines the selection of the receiver, if there is a single device, you can do the passive antenna, if the devices are somewhat and the signal from the receiver is divided “crab”, it is better to purchase Active antenna.

Review of species

Television antennas can be divided into several categories that, in turn, are divided into subcategories. Consider the main of these species.

At the installation site

The location of permanent placement can be both the room and the street. We will analyze the advantages and disadvantages of each type of antennas.

  • Room (home) television antenna. The easiest variety that does not require special installation work. The main disadvantage is weak signals. Often additionally it is equipped with a signal amplifier to improve the quality of reception.

These devices for constructive parameters are divided into the following.

  1. Rod. The people are more famous as “horns”, equipped with two or four mustache vibrators who catch signals. Such antenna due to technical characteristics is compact and easy to develop. The main disadvantage – there is no possibility of a universal tincture.
  2. Frame. The equipment of this type looks like a frame on a metal rod stand. Catch the signal in the decimeter range and require a mandatory installation of the amplifier. Work better core antennas, but not much.

  • Outdoor (street) television antenna. Is a more powerful source of television signals. Such a device is installed on the roofs of multi-storey houses, it is often possible to collectively use. The height of the mast directly depends on the number of barriers for the signal than them more, the higher you need to install the antenna.

By the presence of amplifier

All antennas for this principle are divided into two types.

  • Active. Such devices have power amplifier. The devices of this type are needed if the repeater is located far enough and there are massive barriers, through which the signal is very distorted and does well. Also, the active type of antenna is necessary if the device is located in the lowland, when there is no visibility between the repeater and the television antenna. Such a device can be used for several TVs, for this requires a special tee for an antenna cable.

  • Passive. Ideal antennas for those who live closely from the repeater. The only minus – the signal can go with distortion due to the power of receiving the signal. This question is solved by installing a special console – an attenuator that mutes the signal to the required level.

By construction

According to constructive characteristics, receivers are divided into indoor, outdoor and satellite. We have already spoken about the first two types, therefore we will not particularly emphasize attention. Read more Satellite antennas, they are called “plates”.

This type of device has large dimensions than street or portable home antennas. Receiving signals is carried out from the satellite, and not from the television tower. Device is a massive metal plate, As a rule, painted with white, in which the converter is located, the total number of converters can reach up to 3, it depends on the region of using satellite equipment. Satellite plate is programmed only on one satellite, taking all the channels that it transmits, and the reception of the signals is more than 20 channels, including paid.

Signals broadcast from the satellite and television translator are completely different, so, in addition to the plate, Need to receiver. It looks like a small plastic box with a display on the front panel. There are also a receiver on / off buttons, channel shift, volume and menu, is done in case of malfunction of the remote control. The package is located on the housing, the USB port through which the external flash drive or hard disk is connected, is also used to change the receiver.

A couple of years ago, in the presence of two TV shows in the house and reluctance to watch them the same channel, it was necessary to acquire a satellite antenna for each, but now such a problem is no longer worth. Appeared Universal converters, Their technical equipment allows you to connect two coaxial cables. However, receiver needed for each individual TV, but the plate will be one. Converter Allows you to divide the signals into two streams – and you can watch different channels on different TVs.

Satellite antennas very popular at the expense of high-quality signals even in the area with a complex natural relief, and there are many such places in Russia. Interference in the work of plates, of course, arise, but solely because of strong thunderstorms or abundant snowfall. TO Disadvantages Such devices include the complexity of self-installation.

It is necessary not only to install the equipment at the desired angle and in the right direction, but also to check the quality of the signal.

The modern market offers a great many models of various designs and sizes, from a small home to a large satellite antenna. Of the variety of indoor antennas, thanks to the Internet reviews, we have made an overview of the most successful models.

Selenga 104a Chinese production is compatible with any TVs. Accepts any signals from the built-in amplifier. From minuses, users note the insufficient cable length (only 1.5 meters) and an uncomfortable antenna design.

Next model “Delta K131A. 03 “ Also from China. All reviews on it can be drawn to the following conclusion – it is possible to optimally use this antenna. Only in urban conditions due to the specifics of the Amplifier UHF 40 dB. This amplifier works in the UHF range or the so-called “seventh”, and this range is well catched the waves in the urban trait. In the conditions of the countryside, the waves faster faster, and the signal becomes insecure. Also, the plus is low weight and antenna compactness. Of the minuses – low build quality.

South Korean television antenna model Hyundai H-TAI320 With a closed contour of an unusual design, combined with two antennas-horns provides the widest selection of settings. This is due to the fact that the antenna can take waves in VHF and in UHF bands. Decent quality is achieved by built-in amplifier. Receiving signals in DVB-T, DVB-T2, FM and DAB format. Excellent value for money and quality.

Again the Chinese manufacturer, but not a simple antenna LUMAX DA1502A – Its feature is the possibility of using both inside and outside. According to reviews from the Internet, the device is very high quality and sustainable drops, pleases the cable length – 3 meters. When used as an outdoor equipment for perfect reception of the signal, a rise to a height of 3-4 meters above the Earth. Warranty in 2 years – a nice bonus from the manufacturer.

Another Chinese room antenna Harper ADVB-2120 perfectly proven itself in the Russian market due to its characteristics. These include a large range of captured signals, a unique appearance in the form of a closed ring, which makes it easy to place a design on any surface. The amplifier from this equipment is powered directly from the receiver or TV – it is worth considering this fact when purchasing an antenna, since not any technique may come.

The external antennas are just popular, so we have selected five of the best devices.

  • Russian manufacturer of RaMo releases a fairly good antenna “Ramo BAS-1111-P Pechora” with asymmetric location of elements. Thanks to the special polymer coating, unfavorable weather conditions are not terrible. There is no signal amplifier, so only the antenna is suitable for the resistant signal. Users noted that the quality of reception in such a zone is very good. From the disadvantages it is necessary to note the absence of a cable, bracket, plug and connector, they will have to buy separately.

  • South Korea in its lineup antennas represents the model Hyundai H-TAE240. There is nothing superfluous in the device, it looks very simple. Passive type antenna possesses a durable metal frame. Catching a signal well, but demanding of various interference (high-voltage gear lines, plantings, unfavorable weather).

  • China presented an outdoor antenna REXANT DVB-T2 RX-411 34-0411 Of 8 elements. Receiver with an amplifier, due to this signal quality very good. It is not recommended to install antenna mast below 7 meters, as this may lead to interference. The design is reliable, users note that it works calmly in very unfavorable weather conditions for 7 years.

  • Outdoor receiver Funke ODSC100 from the Dutch manufacturer has small parameters and an attractive design. The model has a coefficient of gain 24 dB and a wide reception of signals in the range of 174-240 MHz / 490 – 862 MHz. It should also be noted the presence of LTE Inert technology with filters and shielding that block interference from other networks. If there is a TV with a DVB-T2, a tuner or a digital console can be connected digital or analog television. The disadvantages are noted by the fact that the power injector and cord.

  • Antenna Locus Meridian 07AF Turbo Fully Russian, with a unique patented high-frequency balance amplifier. The receiver is compact and lightweight, has 7 aluminum elements. In specifications, it is noted that to receive an excellent signal, it is necessary that the TV serves power to the antenna entry, but not all the TV models are equipped. In such cases, the manufacturer advises using the Li Series Power Injector. Owners of such antennas noted that they are ideal for complex areas, rough terrain, height drops.

Satellite antennas, regardless of the manufacturer, work absolutely the same. But among them there are devices that were recognized as the best in work.

Mobile satellite plates represented by brand Azure AS-35T. Among the advantages of buyers noted compact size, installation at any point, reliable assembly and sufficient complete set. Minus just one – the gain rate periodically slows down.

The most reliable satellite antenna offset type was recognized Plate “Supral 0.9 m” from the Ural manufacturer. The benefits are the optimal size, excellent signal reception, storm weather resistance. There is still a lack, and quite serious – no anti-corrosion coating, and rust appears pretty quickly.

The most optimal plate in the price-quality ratio among perforated satellite antennas – LANS-97. Positive parties are: good appearance, fastening, very good signal reception, high corrosion resistance. Due to the transition to the DVB-T2 format, part of the viewers decided to buy a non-digital decoder, but a Japanese antenna advertised “Booster 5G”. Contrary to the assurances of sellers, this device not only does not broadcast federal channels, but also is an ordinary analog antenna. True, for a very expensive fee.

How to choose?

Often the choice of good television antenna is very difficult, because need to take into account the mass of all kinds of factors:

  • Conditions at the place of residence,
  • Distance to translator,
  • Number of channels,
  • Reception quality and many others.

The appearance does not play any role.Room antenna Suitable for a limited number of channels, and the likelihood that qualitatively signal will be accepted on different channels in different ways. Among such receivers it is worth choosing models of directional reception. They are suitable for both old and modern TV.

With outdoor antennas The choice is easier, they can have different dimensions, the main thing is the installation height. Passive type receivers work perfectly in the urban environment, and in the area close to the suburbs or rural, often needed Powerful active type antenna. For the cottage you need active equipment, and taking into account the fact that such sites are most often found for the city feature, it is better if it is an outdoor, for example, Double Square type device.

For the LCD TV most suitable satellite dish. For such antennas, external natural conditions are important, and for good quality work you need to know the satellite frequency. Install and set up the equipment can be independently, but in the absence of experience, it is still better to entrust it with a specialist.

Operating Rules

Purchase of equipment – only the first step to operation. His It is necessary to competently collect, install, connect and check the image quality signal. The process of assembling any antenna is disclosed in the instructions for it, so before work you need to read it carefully. To maintain the operation of the device, you need to observe simple rules.

  1. Installation or dismantling of the device must be carried out by defining it from the outlet.
  2. You can not use a composite coaxial cable, it is better to purchase a cord of a suitable length and replace it.
  3. On the line of operation of the antenna there should be no large objects distorting the signal.
  4. The antenna support should be firmly attached, because at height, the wind is felt stronger than on earth. Support must withstand pretty strong wind gusts.
  5. The antenna setting is enclosed in orienting the signal source and requires a periodic update.
  6. For better compatibility devices, use adapters.
  7. Use only those inputs and connectors that are designed for this.
  8. During the thunderstorm antenna, it is necessary to disable, especially if you have no grounding.

Possible problems

    All types of antennas have problems, and each has common solutions.

    1. TElvizor does not see the connection to the antenna. The cause of the problem can be a cable or malfunction of the TV itself or receiver. It is solved by replacing an antenna cable for a new and repair of equipment.
    2. TV does not show any channel. Often the reason that the signal is missing, the incorrectly selected broadcast frequencies are used. On the satellite plate you need to update the reception of the signal. On room and outdoor antennas it is necessary to check the antenna socket and, if everything is in order, then try a little change the position of the antenna.
    3. TV bad catches a signal from the general antenna. This problem may be caused by three reasons:
    • damage to the coaxial cable;
    • malfunction in the “crab”, splitter or cable outlet;
    • Breaking the connection of the antenna plugs.

    The problem is solved only by replacing the defective part. There are some more problems, but they are highly specialized and demanded to solve special knowledge. The choice of antenna requires a competent approach, it is necessary not only explore the characteristics of television and compatibility with the source of receiving signals, but also choose the model optimal in its qualities.
