Television antenna - when there is a need to choose, many find it difficult to purchase for receiving free digital television for reception. Many for this reason are bought on advertising tricks and there is a high probability to acquire an unimportant antenna for big money.
Hello dear readers! In touch with this blog, Vitaly! In my previous article on this topic, I talked about the antenna known as "key to digital television" and readers of this note very often ask how to choose what antenna to choose?
To respond to once on most of such issues, it was decided to write another article in which there will be a selection of recommended by me and other specialists antennas. As well as some explanations and recommendations. Please read them carefully, maybe it will remove some of your questions.
P.S. The article provides the names of the antennas, but note that they may differ from different manufacturers. This means that the antennas of a similar type and characteristics may be named Locus, Delta, Meridian, Ether, etc. Therefore, it is not necessary to navigate the names, look at the appearance!
All images in the article will be numbered, but it is only for what I could easily specify recommended antennas if you are asking for further. No rating in this numbering! For convenience only. So! Go!
Room antennas
Room antenna Sirius 2.0 without amplifier. Designed for use in the zone of the stable signal. These are populated points in which there are transmitting towers and at a short distance from them, 5-15 km. With direct visibility. 5 dB signal gain coefficient. Such antennas can be executed with an amplifier, but this does not make them suitable for complex conditions of signal reception.
Room antenna with DVS-Z2 amplifier. Although this antenna has a large gain, up to 32 dB (from-out of the amplifier) \u200b\u200bbut there will be a little sense from it. I also recommend using it in the zones of confident reception and at short distances from the tower of 5-15 km. With direct visibility. It can be useful to use such an antenna in the city well for receiving a reflected signal. And it feeds through an antenna plug with a voltage of 5 volts.
Next group of indoor antennas
They have about the same characteristics. These are passive (without amplifier) \u200b\u200bantennas. Alarm coefficient 4-7 dB. But they will be somewhat more effective than the antennas provided above.
These are not bad antennas, they can be successfully used for receiving digital television in zones as a sure signal and at some distance from the TVs. For example, I take a signal on the antennas of this kind from a distance of about 20 km. And from the first floor, but not everyone is lucky!
All this depends on many factors. The power of the transmitter, the terrain, the clutter of high-rise buildings .... In general, if you don't have anything like this at all next to the speakerphone, then these antennas may well handle these antennas.
Indoor antennas with amplifier
These antennas also cope with their task, as well as those without an amplifier. But the amplifier in some cases is useful and helps pull out a weakened signal to an acceptable level. They can be applied not only in the zones of a good signal, but also for example, a slightly complicated or reflected signal.
But still it is room antennas and it limits them. For example, if your windows do not go towards the TV television, and there is no possibility to catch a reflected signal from the opposite side, they may be useless.
By the way! No need to evaluate the reflected signal, you can watch digital television perfectly on it.
Locus L999.06 Next - Active broadband antenna. Comes in disassembled form. The amplifier is powered by a voltage of 12 volts from the external power supply. The gain of DMB 23-27 dB.
Locus L922.06 Not a bad room antenna. It looks neat, there are options with an amplifier and without it. The version with the amplifier is equipped with a power regulator, which can very helpful.
Delta K131A.02 And the other two of the above bands are also active antennas, but with 5 volt amplifier supply voltage. It can be served directly from the prefix DVB-T2 or through a special injector with a USB port of LCD TV. The gain of these antennas to 22-27 dB.
Active antenna Cayman - It may be in two versions 1) with power through an antenna plug. 2) With an already built-in injector for powering from the USB port, which is very convenient for use with LCD TVs with this port. No need to acquire an additional 5 volt power supply with an injector and take another outlet.
Street antennas for digital television
Go to more serious designs, the task of which to provide a quality signal where the room antennas can not cope. Repair ratio from 19 dB to 35 dB.
These are antennas that can be applied in more complex conditions and several large distances. If you have noticed, they are structurally similar to room antennas, but only a little more. And this is the important factor that makes them more powerful. The longer arrow in the antenna, the greater the coefficient of its own amplification. This is the gain that is achieved without at the expense of the amplifier, and at the expense of the antenna design. A installed amplifier only "rolls" this signal is even stronger.
In addition, the street installation allows them to be more accurately directed onto the computer by passing the obstacles in the form of walls.
Kholib - Interesting antenna. Works both in meter and in the DMB ranges. Its feature, an unusual design, which, with small dimensions, provides a fairly good signal reception. Very convenient in urban conditions and to search for a reflected signal, a short length allows you to install it in a limited space. It has several modifications and can be supplied with power amplifier for both 12 and 5 volts.
Locus -14 AF. - This antenna also has several modifications, the designation AF- with an amplifier, F - without an amplifier. There are also Locus - 20 AF / F is characterized by a longer arrow, and therefore even a large coefficient of its own gain. The amplifier works from 5 volt voltage.
Delta H3111.02 - There are also options with an amplifier and without it, moreover, it may be under a different name (depends on the manufacturer) and differ in the way to connect a television cable to it.
Meridian - 07 AF — Made of aluminum.
Antennas at 11 -14 numbers are good antennas, and only "Hummingbirds" will be somewhat more expensive.
They can be applied at a distance of up to 30 km. But again, if there are factors that create interference with the passage of the signal, then even more of the short distances may need an even more powerful antenna.
Powerful digital television antenna
These antennas are good for long distances and even more difficult conditions, for example, if your home in a strong lowland is located.
At what distances can you apply them? For example, I had to put 18AF ether (by the way, not the strongest in this triple) on a house in 45 kilometers from the TV TV. The house was at the same time in the lowland, and the antenna fastened the roof of the roof at the ridge, there she was sticking out some pin, and attacked the antenna. Everything is perfectly taken!
Ether 18. - Steel antenna, painted powder paint, there are options with an amplifier and without it. The letter A in the title indicates that the antenna is active, with an amplifier. If in the title only f, then this is an antenna without an amplifier. The antennas Meridian -12 AF / F are also labeled
Meridian-12 and Triton - Made of aluminum and even more powerful than ether-18. The reason is not only in the material, but also in the design. For example, the antenna "Meridian" is about 1.5 meters long. And Triton has short arrows, but they are already three pieces. This is a sum as one long.
Active antennas from this triple have amplifiers feeding from 5 volts. What is convenient for use with DVB-T2 consoles. Triton antenna also has an injector for nutrition via USB, which is indicated in the marking. The gain coefficient of these antennas reaches 35 dB. Due to the amplifier. But thanks to their design, the amplifier is, what to strengthen)))
THOSE. The antenna itself pulls the signal from the ether to the level of about 10-12 dB (this is called its own antenna gain) and the amplifier accelerates it to the level of 35 dB.
The most powerful antenna for DVB-T2
Well, if you carefully read the previous descriptions, then you should be clear why these antennas are the most powerful of those presented in this review.
For example, the Goldmaster-GM500 antenna is a bandless antenna, without an amplifier. But the coefficient of its own amplification is only due to the structure of the whole 22 dB. Such an amplification is given by middle antennas and then at the expense of the amplifier. And here in pure form!
The following antennas from this "red zone" are as effective, plus also active. Their amplifiers feed on 5 volts. Those sharpened under digital consoles. Or, if you do not use the prefix, since they bought a telly with DVB-T2, then you will need a separate power supply for antenna, 5 volts or injector for USB power.
This is the class of antennas that you need to take if you live on the distance from the transmitting tower from 50 km and then you have a very complex zone for receiving TV signal.
Why not need to seek an antenna with an amplifier
It is noted that the word "amplifier" has a magical property! And when a person chooses an antenna, he prefers precisely such, active antennas. Why is this erroneous point of view?
- In the zone of confident reception, the amplifier can lead to the fact that your TV / prefix will not accept anything at all! Cause, transaction signal!
- The amplifier enhances not only a useful signal, but also a radio noise. A useful signal, pulls the antenna design!
- Amplifier is always a weak link in the antenna design. He fails, his thunderstorm beats him, he oxidizes from moisture. As a result, periodic interference requires an antenna repair.
- It is required to provide power to the amplifier located in the antenna, and this is another additional weak link, the adapters fail and require replacement. In addition, another connection point is required, socket or USB port, and this is not always comfortable!
- In case of connection, it is much easier to do with an antenna not having an amplifier.
When the amplifier needs
- If the total length of the television cable exceeds several tens of meters.
- If you live on a high distance from the transmitting tower, in the zone of the low signal and the design of the antenna itself does not allow "pull out" the signal to the desired level.
Conclusion! - If at the place of your stay it is possible to confidently receive a signal to an antenna without an amplifier, always strive for an antenna without an amplifier!
How to feed meals on an active antenna amplifier
There are several ways to feed the antenna amplifier.
- If you use a digital prefix, then the food is served directly from it, by an antenna cable. No need to wise anything. Just go to the Prefix menu and find the Power Power. On "in different models of the consoles, this inscription may differ, but the essence is one. Turn on the power on the antenna! Even if the amplifier in antenna is 12 voltet, often 5 volts from the console will be enough.
- If you do not use the prefix, then you will need a special adapter with an injector that can be connected to the USB port of the TV and so to power the antenna to the USB. Or purchase an antenna with power through USB. These methods are very convenient for LCD TVs, especially hanging on the wall.
- A classic method, through an antenna power supply with an appropriate voltage amplifier.
Well, perhaps on this and finish! In the heading "Television" of this blog, there are still many articles on the topic of antennas, digital consoles and television.
