Just a surprise - WHO is a radio amateur now?
TO RADIO FANS, -73, to the rest of the "fishermen" is a simple FIASCO.

I would like to know at what distance from the tower such an antenna works ...

Korolev,
These are the needs of the population, but business has other interests.
-Not only the needs of the population, but also the interest of the state. It was not necessary to invest in a figure that would die in 5-10 years, but to subsidize the development of networks.
But I agree with you. Even many large state projects are not focused on profit making by the state. Plato, online checkout, and even cameras on the side of the road.

These are the needs of the population, but business has other interests, and we still have antitrust laws! yes

Well, in fairness, for the sake of 8500, plus equipment. That's 10. And from a private trader 2500 + a 1500 router for Wai Fai took. But he only came to us last year. Now another office comes in. And Rostelecom will remain with its telephone wire.

Well, yes, Rostelecom as a monopolist. But something you have too high prices. 10 rubles from a private house is a bit much.

R555,
That is the question, what would they not take off. Those. not in numbers, but in optics.
So I announced the price of connecting with Rostelecom (they said in the call center). But the fact is, I asked a local engineer, and he says that nobody will pull you optics. And the settlement, well, probably already 15 thousand people.
I then connected to a private office, but in Rostelecom, it’s the state’s share.

pogranec,
Here, too, is not so simple. There are farmsteads with 5 yards in total. And how many rubles should they be thrown off so that optics can be dragged to them?

In my opinion, as always we went the wrong way. I'm not talking about the antenna, but about the "number". Instead of investing billions in the development of digital TV, it was necessary to develop high-speed CHEAP Internet. Over time, all the same, everyone will switch to it. To every village and farm. Here and the Internet and TV and smart home + video surveillance.
And we have to connect the optics to a private house near Rostelecom Chervonets.

The author is well done! Great invented and executed. By manipulating the position of the telescopic antenna, you can change the polarization as you like.

I will explain from myself. It happens that there is a reflected signal from various objects. The reflected signal arrives simultaneously with the direct input to the set-top box or TV and this leads to unpleasant phenomena, up to the disappearance of the image. So, a change in the position of the receiving antenna allows us to get rid of this. And the polarization may not necessarily be strictly vertical or horizontal. Maybe, for example, help out 45 degrees.

R555,
And by manipulating the length of the telescopic antenna, you can more accurately tune to the desired part of the range. Although at these frequencies the channels are very close.

The author did not indicate in the article that the second “horn” of this antenna is braided by the cable.

And in conclusion, I want to say that the amplifier is correctly set, or rather the antenna. Stuck directly into the amplifier input good
