Good day!
They say that "best the enemy of the good..."and maybe that's right. In general, analog TV provided a very good quality of broadcasting even in many remote corners of our country.
Replacing it with a digital one (let me remind you that in June / July this year the whole of our country begins to switch to it) - many are faced with the fact that the broadcast quality has dropped noticeably, and they cannot watch TV as before, because the image twitches, goes "cubes", the sound stutters, some freezes, etc. Moreover, this happens not somewhere in a remote area, but next to large cities (and in them too)!
What is more characteristic: if earlier it was possible to catch several channels very tolerably ("First", "Russia" and a number of others), now if the broadcast is jammed, then you can not watch any of the TV channels ...
In this post I will give a few recommendations that can help reduce interference and improve broadcast reception (a lot, of course, depends on your location and the equipment used).
And so, closer to the topic ...

What to do if digital TV shows poorly, with interference
❶
Check which channels in your area should be broadcast
The equipment (TV, antenna, amplifier, etc.), the area and the location of the house relative to the broadcast tower have a very large impact on the quality of reception. If your house is located in the middle of the forest (conditionally) and the TV tower is very far from you, then you should not wait for a good reception (as before) ...
In general, to begin with, what I recommend to do is to check on the official website //rtrs.ru/ which of the digital TV channels are available in your area. Usually these are 2 digital packages RTRS-1 and RTRS-2, which include 20 free channels: First, Russia, Match !, NTV, 5th, TVTs, Zvezda, Spas, TV3, TNT, Zvezda, Friday !, Muz- TV, etc. (see screen below).
What channels are shown in my area
In addition, on the same site you can see the coverage areas and broadcast frequencies specifically for your region. Despite the fact that in June 2019. almost the entire country should switch to digital broadcasting - there are still corners where this does not exist ...

What's with the cable and plug
The cable has a very strong effect on the transmission of the captured signal by the antenna. And for many people his condition leaves much to be desired not even the best (but the best 👌).
In general, if you encounter any interference when setting up digital TV, be sure to check the condition of the cable and plug. Is there any twists on it, is it intact at all (sometimes it is gnawed by pets).
Twisting the cable ...
In addition, try to avoid various doubles, tees, etc. Ideally, for good reception, you should have a solid cable from the antenna to the TV without any twists. If it is necessary (for example, there is no way to replace the cable with a new one), then get better specials in this place. F-socket. (for more details on the correct cable connection).
❸
Pay attention to the antenna
The biggest influence (besides your location) on signal reception is the antenna (and its placement, but that's the next point). As a rule, if an antenna was included with your TV tuner (receiver, TV), it is small and weak: it can provide normal reception if you are no further than 10-15 km from the TV tower (moreover, there are no then serious obstacles).
Antenna from a TV tuner (example)
That is why, from such an antenna (see the example in the photo above), I would recommend refusing.Even a homemade antenna made from old aluminum cans can provide much better reception.

If such conventional antennas receive a signal poorly, I recommend paying attention to outdoor antennas with an active amplifier (for DVB-T2). Why exactly this? The fact is that indoor antennas receive a signal much worse than outdoor antennas (especially when it comes to a country house). Well, the active amplification will significantly improve the received signal (note that there are also passive amplifiers - they are usually somewhat weaker).

❹
A few words about the location of the antenna
Received signal quality can vary greatly depending on antenna placement. Even weak indoor antennas in one place of your apartment can pick up a signal, but not in another.
You can recommend trying to connect the antenna to the TV, and then experiment with its location: first put it by the window in one room, then in another, etc.
Of course, using an external antenna will greatly increase the reception level. Moreover, pay attention to one point: installing the antenna 2-3 meters higher than the level of trees and buildings in the immediate environment - can give amazing results!

❺
Weak signal due to bad weather ...
If there is a heavy downpour, thunderstorm, blizzard, etc. outside the window. etc. - all this can affect the reception of terrestrial DVB-T2 television. At this time, the broadcast is usually spasmodic, intermittent (and nothing can be done about it).
Storm...
By the way, in the case of ordinary classic television, when the signal deteriorated, the picture was distorted (red horizontal stripes appeared), but it could still be watched. With digital television: when the signal level decreases, it becomes impossible to watch the broadcast 😢 ... And in this regard, I do not understand what is the advantage of the new broadcasting format ...

❻
Cable TV can be connected
If all of the above did not help, then, as an option, you can connect either cable TV or install a satellite dish. Whether you live in the city or the countryside, one of the connection options will almost certainly be available.
By the way, it should not be noted that the cost of such equipment has significantly decreased compared to what it was 10-15 years ago. Moreover, now some companies provide equipment for free, provided that you use it for 2-3 years. In general, there are options ...

❼
You can watch TV on the Internet
Well, I can't help but note that with the development of networks in our country, many users have the opportunity to watch TV over the Internet. Moreover, for this it is not at all necessary to be the owner of high-speed Internet access (the main thing is that the connection is stable and not "interrupted").
How to set it up - I have a separate blog post, the link to it is below.
