Receiver dvb t2 antenna power supply. The correct antenna for receiving DVB T2 digital television at the dacha. How to turn on antenna power on an LG TV
It seems that it could be simpler than plugging the antenna plug into the antenna socket of the digital receiver and the “bell” plug into the TV and after automatic tuning you can watch football or cartoons on digital television. In general, “that’s it, that’s how it is, but just a little bit ts and not like that,” Mikhail Pugovkin’s character used to say in one of the films. films.
How to connect an antenna
There are some points when connecting several digital terrestrial receivers to one antenna, which I want to outline in this article. If for viewing digital programs the usual one is usedpassive antenna, it is enough to apply - a splitter and that's all. But the fact is that now very good ones have appeared on the market antennas forDVB- T2 that have an amplifier TV signal, the power supply of the amplifiers on these antennas is designed for a voltage of 5 Volts and these volts are supplied directly from the receiver itself. that is, a power supply is not included with such an antenna; the function of the power supply is performed by the receiver itself. This is very convenient, but creates some difficulties when connecting several receivers to one antenna. Several connection options are available.
Option one“ consistent” .
With this option, the set-top boxes are connected in series, the antenna output of the first set-top box is connected to the antenna input of the second set-top box, from the output of the second, to the third, and so on.
In the options of the first receiver, the antenna power is set to ON; on the remaining set-top boxes in the chain, the antenna power cannot be turned on.
For example, Oriel-203 is generally not bad budget receiver, does not have such an option, so if you choose serial connection, terrestrial digital receiverDVB- T2 must have an antenna output plug.
Another disadvantage is that the antenna amplifier is powered by the first receiver, and if this receiver is turned off, the other receivers will also not work, since the antenna amplifier's power will be turned off. You will have to keep the first receiver constantly on, and if the first receiver fails -An urgent replacement is required otherwise there will be no leakage.
As a temporary replacement for a receiver that has failed, you can connect the antenna input and output plugs (since they are “male and female”), and then supply power from a second working receiver.
Option two with a diplexer.
For the second option you will need For this connection option, any receivers are suitable, availability additional output no antenna required.
IN in this case, You turn on in the options of all set-top boxes, power to the antenna amplifier and with any set-top box on antenna amplifier supply voltage will be applied. Personally, I don’t see any disadvantages in this connection method, except that you have to fork out for a splitter.
How to connect the set-top box to the TV.
To connect to a TV, the digital DVB-T 2 receiver has several output connector options.
The most common is the RCA plug, the familiar “bells”, these bells can be connected to almost any TV. The signal transmitted through RCA is analog, i.e. digital signal, received from the air is converted to analog.
Connector HDMI is also available on all digital receivers Unlike RCA, a digital signal is transmitted via HDMI; this connection is preferable. Many modern televisions who don't have their own digital tuners can be connected via HDMI
Television antenna - when the need to choose arises, many find it difficult to decide which antenna to buy to receive free digital television. For this reason, many people buy into advertising gimmicks and there is a high probability of purchasing an unimportant antenna for a lot of money.
Hello dear readers! The author of this blog, Vitaly, is in touch! In my previous article on this topic, I talked about the antenna known as “The Key to Digital Television.” And readers of this note very often ask the question of which antenna should they choose?
In order to answer most of these questions at once, it was decided to write another article which will contain a selection of antennas recommended by me and other experts. And also some explanations and recommendations. Please read them carefully, perhaps this will answer some of your questions.
P.S. The article gives the names of the antennas, but please note that different manufacturers they may differ. This means that antennas of a similar type and characteristics can be named LOCUS, DELTA, MERIDIAN, ether, etc. Therefore, it is not necessary to focus on the names given, look at the appearance!
All images in the article will be numbered, but this is only so that I can easily indicate the recommended antennas if asked about this in the future. There is no rating in this numbering! For convenience only. So! Go!

Indoor antennas
Sirius 2.0 indoor antenna without amplifier. Designed for use in a stable signal area. This settlements in which the transmitting towers are located and at a short distance from them, 5-15 km. With line of sight. Signal gain 5 dB. Such antennas can also be made with an amplifier, but this does not make them suitable for difficult conditions signal reception.
Indoor antenna with amplifier DVS-Z2. Although this antenna has a high gain, up to 32 dB (due to the amplifier), it will be of little use. I also recommend using it in areas of reliable reception and on short distances from the tower 5-15 km. With line of sight. It is good to use such an antenna in the city to receive the reflected signal; an amplifier can be useful for this. And it is powered through a 5 volt antenna plug.
The next group of indoor antennas
They have approximately the same characteristics. These are passive (without amplifier) antennas. Signal gain 4-7 dB. But they will be somewhat more effective than the antennas provided above.
Is not bad antennas, they can be successfully used to receive Digital Television in areas with both a strong signal and at some distance from television towers. For example, I receive a signal via antennas this kind of from a distance of approximately 20 km. and from the first floor, but not everyone is so lucky!
All this depends on many factors. Transmitter power, terrain, clutter with high-rise buildings... In general, if there is nothing like that very close on the way from you to the TV tower, then these antennas can handle it quite well.
Indoor antennas with amplifier
These antennas cope with their task approximately as well as those without an amplifier. But an amplifier in some cases turns out to be useful and helps to pull the weakened signal to an acceptable level. They can be used not only in areas good signal, but also, let’s say, a slightly complicated or reflected signal.
But still this indoor antennas and this limits them. For example, if your windows do not face the TV tower, and there is no way to catch the reflected signal from the opposite side, they may be useless.
By the way! There is no need to underestimate the reflected signal; you can watch digital television perfectly on it.
Locus L999.06 Next — Active broadband antenna. Supplied unassembled. The amplifier is powered by 12 Volts from an external power supply. UHF gain 23-27 dB.
Locus L922.06 Not a bad indoor antenna. It looks neat, there are options with and without an amplifier. The amplifier version is equipped with a power control, which can be very useful.
Delta K131A.02 and the other two from the above group are also active antennas, but with an amplifier supply voltage of 5 Volts. It can be supplied directly from the DVB-T2 set-top box or through a special injector with USB port and LCD TV. The gain of these antennas is up to 22-27 dB.
Active antenna Cayman , - can be in two versions: 1) With power supply via an antenna plug. 2) With a built-in injector for power from the USB port, which is very convenient for use with LCD TVs that have this port. There is no need to purchase an additional 5 volt power supply with an injector and occupy another outlet.
Outdoor antennas for digital television
We move on to more serious designs, the task of which is to provide a high-quality signal where indoor antennas cannot cope. Gain from 19 dB to 35 dB.
These are antennas that can be used in more difficult conditions and at slightly longer distances. If you noticed, they are structurally similar to indoor antennas, but only slightly larger. And this is the one important factor which makes them more powerful. The longer the arrow in the antenna, the greater its own gain. This is the gain that is achieved not by the amplifier, but by the design of the antenna. A installed amplifier only “rocks” this signal even more.
In addition, outdoor installation allows them to be more accurately directed at the TV tower, avoiding obstacles in the form of walls.
Hummingbird — Interesting antenna. Works in both meter and UHF bands. Its peculiarity is its unusual design, which, despite its small dimensions, provides quite good welcome signal. Very convenient in urban environments and for searching for reflected signals; its short length allows it to be installed in limited space. It has several modifications and can be equipped with an amplifier with both 12 and 5 volt power supply.
Locus -14 AF — This antenna also has several modifications, designated AF - with an amplifier, F - without an amplifier. There is also Locus - 20 AF/F, which has a longer boom, and therefore an even greater self-gain coefficient. The amplifier operates at 5 volts.
Delta N3111.02 — There are also options with and without an amplifier, in addition, it may have a different name (depending on the manufacturer) and differ in the way the television cable is connected to it.
Meridian - 07 AF — Made of aluminum.
Antennas numbered 11 -14 This is good antennas, and affordable, only “Hummingbird” will be slightly more expensive
They can be used at a distance of up to 30 km. But again, if there are factors that interfere with the signal, then even at closer distances you may need even more powerful antenna.
Powerful antenna for digital television
These antennas are good for long distances and even more difficult conditions, for example, if your house is located in a strong lowland.
On what long distances can they be used? For example, I had to install Ether 18AF (by the way, not the strongest in this trio) on a house located 45 kilometers from the TV tower. The house was located in a low area, and the antenna was attached to the ridge of the roof of the house; there was some kind of pin sticking out there, and the antenna was attached to it. Everything is being received perfectly!
Ether 18 — The antenna is made of steel, powder-coated, there are options with and without an amplifier. The letter A in the name indicates that the antenna is active, with an amplifier. If there is only F in the name, then this is an antenna without an amplifier. Meridian -12 AF/F antennas are also marked
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 Meridian antenna is about 1.5 meters long. And the Triton has short arrows, but there are only three of them. It adds up to one long one.
The active antennas of this trio have amplifiers powered by 5 Volts. Which is convenient for use with DVB-T2 set-top boxes. The Triton antenna also has an injector for power via USB, as indicated in the labeling. The gain of these antennas reaches 35 dB. due to the amplifier. But thanks to their design, the amplifier has something to strengthen)))
THOSE. the antenna itself pulls a signal from the air at a level of approximately 10-12 dB (this is called the antenna’s own gain) and the amplifier accelerates it to a level of 35 dB.
The most powerful antenna for DVB-T2
Well, if you carefully read the previous descriptions, then you should understand why these antennas are the most powerful of those presented in this review.
For example, the GoldMaster-GM500 antenna is a passive antenna, without an amplifier. But its own gain, only due to the design, is as much as 22 dB. Such amplification is provided by mid-range antennas, and then only at the expense of an amplifier. And here in its purest form!
The following antennas from this “red zone” are just as effective, plus they are also active. Their amplifiers are powered by 5 Volts. That is, they are designed for digital set-top boxes. Or, if you don’t use a set-top box because you bought a TV set with DVB-T2, then you will need either a separate power supply for the antennas, 5 volts, or an injector for power from USB.
This is the class of antennas that you need to take if you live at a distance of 50 km or more from the transmitting tower and have a very difficult area for receiving a TV signal.
Why you don't need to strive for an antenna with an amplifier
It has been noticed that the word “Amplifier” has some kind of magical property! And when a person chooses an antenna, he gives preference to just such active antennas. Why is this a wrong point of view?
- In the area of reliable reception, the amplifier can lead to the fact that your TV/set-top box will not receive anything at all! Reason: over-amplification of the signal!
- The amplifier amplifies not only the useful signal, but also radio noise. And it is the antenna design that pulls out the useful signal!
- The amplifier is always the weak link in the antenna design. It fails, it is hit by a thunderstorm, it oxidizes from moisture. As a result, periodic intervention in antenna repair is required.
- It is necessary 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, socket or USB port is required, and this is not always convenient!
- If connected, this is much easier to do with an antenna that does not have an amplifier.
When do you need an amplifier?
- If the total length TV cable exceeds several tens of meters.
- If you live at a great distance from the transmission tower, in the area weak signal and the design of the antenna itself does not allow “pulling” the signal to the required level.
Conclusion! - If in the place where you live it is possible to confidently receive a signal on an antenna without an amplifier, always strive for an antenna without an amplifier!
How to power up an active antenna amplifier
There are several ways to supply power to an antenna amplifier.
- If you use a digital set-top box, then power is supplied directly from it, by antenna cable. There is no need to be clever. Just go to the console menu and find the “Ant power supply” item. on" B different models consoles, this inscription may differ, but the essence is the same. Turn on power to the antenna! Even if the amplifier in the antenna is 12 volt, often 5 volt from the set-top box will be enough.
- If you do not use the set-top box, then for power active antenna You will either need a special adapter with an injector that can be connected to the USB port of the TV and thus power the antenna. Or purchase an antenna powered via USB. These methods are very convenient for LCD TVs, especially those hanging on the wall.
- The classic way, through a power supply for antennas with a voltage corresponding to the amplifier.
Well, I guess I’ll end here! In the “Television” section of this blog, there are many more articles on the topic of antennas, digital set-top boxes and television.
This is the simplest terrestrial DVB-T2 receiver that connects to TVs or monitors (some types) for watching digital television. It has HDMI, YPbPr (component) video output, composite RCA output, digital coaxial audio output, USB 2.0 port to which you can connect external drives for playing (as a media player) and recording (including scheduled) television programs. As a media player, the receiver supports popular video and audio formats, and has a Timeshift delayed viewing mode (if there is a connected drive).

And here is the receiver. The case was covered with a protective film, partially blocking access to the ventilation holes.
Weighed it. 291g.
The front panel is made of plastic and contains a USB connector, an IR sensor, an LED indicator (two-color: red in standby mode, green in operating mode), as well as buttons for switching channels and turning on the receiver. 
The display had a protective film. I've already taken it off.
The rear panel contains antenna input and output connectors (the receiver supports pass-through), a coaxial digital audio output connector, an HDMI connector, three YPrPb component video output connectors, and three RCA connectors for transmitting composite video and stereo audio.
The purpose of each pin is described in the instructions. 
The kit included a cable for connecting analog video and audio signals (RCAx2 (L / R)). 
The remote control was in a separate package. 
An ordinary remote control, nothing special. It fits comfortably in the hand.
See the instructions for the purpose of the buttons. 
There is some confusion about the purpose of the buttons. But more on that at the end of the story.
The remote control is powered by two AAA batteries. 
Batteries are not included.
I took it apart just in case. Nothing interesting inside. 
I'll see what's inside the receiver.
I unscrew 4 screws. 
Everything is very compact. The power supply and receiver are located on the same board. There are cuts between the primary and secondary circuits in the board. There is a fuse at the entrance. 
Power supply with galvanic isolation.
The MSTAR MSD7T01 processor serves as the “brain”. 
It's time to see what he (the receiver) can do.
The device was connected to a LETV X3-40 FHD LED Smart TV.
When turned on, you are asked to select the menu language, country and start searching for channels. 
I chose Russian as the language and Russia as the country.
There are two multiplexes broadcasting in Tambov. 
TV (LETV) allows you to take screenshots. That's why I joined him. All photos with original resolution. Didn't change anything. 
This is what the main menu looks like (press the “MENU” button). 
The controls are intuitive. We move the arrows. Confirm with the OK button. 
When you select “Channel Editor” you will be asked to enter a password. To edit, enter zeros (as a password).
Channels can be moved, skipped, blocked, deleted, added to favorites and renamed. 
This is the next line of the menu (TV guide). 
You can schedule both recording and viewing. 
I move on to the next section of the Menu - “Video” contains settings for screen proportions, resolution (1080P 60HZ, 1080i, 720p, 576p, 576i) and a choice of PAL and NTSC standards. The choice of standards (PAL and NTSC) when transmitting a signal via HDMI does not affect the image in any way. 
Users have a choice of different screen formats:
-Auto
- 16:9 PillarBox
- 16:9 Pan&Scan
- 4:3 Letter Box
- 4:3 Pan&Scan
- 4:3 Fullscreen
- 16:9 wide screen.
I move on to the next section of the Menu. In the “Search for channels” section, you can repeat the automatic search for channels, turn on or off additional antenna power, and filter out encrypted channels (if relevant).
You can use a manual search.
Now the next menu item.
Here you can select your time zone and region. The region can only be selected Moscow (in auto mode). In manual mode, select the time zone correction (the DVB-T2 standard supports time transmission). 
You can also configure auto-shutdown (from 1 to 12 hours with an interval of 1 hour) and the time to turn on/off the device. 
The next menu is language. 
System settings allow you to activate parental controls, 
Set password, 
restore factory settings (password is still the same zeros), 
get information about the software 
and update the software. 
I did not do this procedure. So far everything is fine. 
Last menu item. 
To play and record video files, you must connect a USB device.
Records with MTS extension.
The MTS extension is associated with video files that are used in the AVHCD (Advanced Video Coding High Definition) video format. AVHCD video format was developed for tapeless camcorders. Video can be recorded with a camcorder that records files to a DVD, hard drive, solid-state drive (SSD), or memory card (SD, Memory Stick). The AVHCD MTS format was developed by Sony and Panasonic and was introduced in 2006. The AVHCD video format is now used by camcorders from such manufacturers as Sony, Panasonic, Leica, Canon, Hitachi and JVC (JVC uses AVHCD and its own video format with the TOD extension).A recording lasting 1 minute takes 23-24MB of space.
The MTS file uses MPEG-4AVC/H.264 (AVC) video encoding. Maximum video resolution 1080i. Audio is encoded with Dolby Digital AC-3 audio codec. Some professional camcorder models support audio in uncompressed linear PCM format. AVHCD video format is designed to be fully compatible with Blu-Ray video format. AVHCD videos can be played in Blu-ray players without using encoding.
You can look at an example entry:
Characteristics of the recorded file:
Video: MPEG4 Video (H264) 720x576 (20:11) 25.00fpsTo record programs and use the Timeshift delayed viewing mode, you need a USB drive connected to the USB port, and it is absolutely not necessary to go to the Menu. There are specially dedicated buttons on the remote control for this purpose. We count from left to right, from top to bottom.
Audio: MPEG Audio 48000Hz stereo 192Kbps
Subtitle
The first “USB” button opens the menu item of the same name. The second button enables video recording.
The fourth button activates Timeshift. The image on the screen freezes (pause mode) and recording to the USB drive begins.
After drinking tea or coffee, press the same button and continue watching the program you like.
The third button turns off video recording/disables Timeshift.
Rewinding a track (the first two buttons in the second row) allows you to increase the viewing speed (x2, x4, x8, x16, x32) by sequential pressing.
The next two buttons provide access to the previous or next video file.
Use the green and yellow buttons to change the screen resolution and proportions.
The receiver also allows you to receive teletext signals.
At the end there is some information for extras.
The receiver does not heat up much during operation. Power consumption from the network is only 5.4 W. In standby mode 1.1W.
Connected an external hard drive as a storage device. Not enough power. SSD works fine.
It's time to move on to the final part. I'll highlight what I liked and didn't like. The point of view is subjective.
Pros:
Fully compatible with DVB-T2 format:
built-in power module (no adapter required);
metal case;
Availability of Timeshift delayed viewing mode (if there is a connected drive);
availability of on and off timers;
HDMI output for viewing high-quality images;
recording TV programs to external USB drives;
convenient multilingual menu;
support for teletext and subtitles.
Minuses:
lack of display;
absence of any hints about the manufacturer.
And one more thing at the end.
I told about the device that I hold in my hands. He pointed out all the pros and cons. Everything I noticed, I wrote about everything.
If something is unclear, ask questions. I hope it helped at least someone.
That's it.
Good luck!
The product was provided for writing a review by the store. The review was published in accordance with clause 18 of the Site Rules.
I'm planning to buy +59 Add to favorites I liked the review +34 +83- do not use the one bought when your grandfather went to first grade;
- don't buy the cheapest one with virtually no braid. Choose normal ones;
- do not shorten as much as possible;
- do not make sharp creases;
- Do not roll the excess into a coil.
Even if you connect the pieces with a standard coaxial connector, the signal quality is guaranteed to deteriorate.
Using the amplifier
This inexpensive antenna for the garden gives good results. If you plan to receive only with this antenna, then its two long side “whiskers” can be unscrewed.
Wave channel
They give good results, especially for remote signal reception when it is quite weak.
Polish
Many TV viewers use the “Polish” antenna - a grid and four rows of antennae. It doesn’t matter where it was made, they used to call it “Polish”, and sometimes “mesh”. Very often it does not demonstrate the best characteristics for receiving a digital signal.
In general, for reception at the dacha , very sensitive too. If the reception of the digital signal on it in your area turns out to be normal, then you are just lucky. The amplifier of this antenna can be powered by 5 Volts, which can be taken from a digital tuner, and then there is no need to use an additional power supply.
Zigzag
indoor antenna shows good results for . Even if you paid dearly for it, the result may be zero.
If you only want an indoor antenna as an on-air antenna for your dacha, you may be “advised” to buy it more expensive and “better”. But if you hope that she will start giving you a wonderful signal in your room, then this hope is in vain. If there is a bad signal in the house, no antenna will help. External - this is the solution to the problem if there is no reception in the room.
Satellite
Remember? We're talking about ethereal, so forget about satellites. You will not receive terrestrial television in the DVB-T2 standard through a satellite tuner. You will not connect the T2 tuner to the . We receive the T2 signal from the nearest broadcast tower in the UHF range. To a regular over-the-air antenna for a summer residence, not a “dish”.
