At first I decided to install it behind a TV set, as a result, channels were found only from the second multiplex. I got on the Internet and found out what the first and second multiplex are, I also found out what needs to be directed towards the broadcasting tower, and it’s better to put it as high as possible and preferably on the window, but it was enough for me that it was next to the TV set, but I placed it in the direction of the broadcasting tower and it worked had!
