In Rostec, announced the development of a new generation of ship antennas

In Russia, the development of a new generation of receiving and transmitting antennas for surface ships and coastal communication centers has been completed. The development was carried out by the Omsk Scientific Research Institute of Instrument Engineering, which is part of the holding Roselektronika (Rostec). This was reported by the press service of the state corporation.

Antiaircraft antennas improve the quality of ship communications, reducing the influence of the electrical properties of the earth, sea waves and terrain. The equipment is designed to transmit a signal using the ionosphere. Radiation directed to the zenith is reflected from the upper atmosphere at small angles and densely covers the zone in a radius of up to 800 km

- said in a statement.

New equipment can be used to organize radio communications in noise-protected modes, and the broadband equipment increases the stability of signal reception and transmission. It is noted that the equipment can be used on ship superstructures made of composite materials, since it has reduced requirements for the underlying surface.

(...) new types of antennas and antenna-feeder devices are created that increase the quality and range of signal reception and transmission. A great deal of experience is now being used in the development of new ship communication systems that can be applied on ships of distant sea and ocean navigation zones

- said the Executive Director of Rostec Oleg Yevtushenko.

HF is our everything

It is difficult to call this direction science. The propagation of radio waves in the ionosphere, a very capricious thing. There is more empiricism than science.

[Operator]

In this case, not distribution, but a golem omnidirectional reflection.

Yes, the passage of radio waves is a very dark matter. Confident transmission and reception depend on many reasons.

But as bizarrely Radio waves spread in the mountains! This is oooooo !!!

[TermNachTer]

In the mountains it did not happen, but there were enough misunderstandings on the sea, although it seemed no obstacles except the curvature of the Earth's surface.

In, in! Now imagine WHAT is going on in the mountains! Even the joke was like this: "There are two absolutely incomprehensible things:
a) - "the ways of the Lord";
b) - radio wave propagation.
Somehow, even one soldier envied his marine colleagues - they say it's good - the surface is flat (well, or almost flat), except for the scallops of waves ... To which he received the answer: "Everywhere is good, where not! And there are problems there too. (at sea) probably “above the roof.” It's funny, but now you have confirmed it!

Once upon a time, working at the NMP radio center, I somehow worked in Creed with a steamboat on the PV, which was in the Red Sea. QSA 5 points! True at night when layer D is absent. But still an anomaly!

It happens. Even on VHF, one can sometimes hear overwhelming distances. There was a case when a ship, being in the Avacha Gulf, contacted Vladivostok via VHF. Not a bike.

[TermNachTer]

I heard a similar story, although I myself have not seen or heard, because for what I bought, I sold for that. The vessel leaving the BDLK contacted the "Reid" on the 16th channel, with the steamer, which was leaving the Bosphorus.

You still know little about the propagation of sound waves. There are many incomprehensible things in the world.

What can I say in response to these incomprehensible minuses? The clever person understood, and it’s not my task to explain the moron, thank you.

[Amateur]

Nonsense. Decided to resume tropospheric communication? Or again a free retelling of something normal.

Nonsense.

You know better, probably ... And the men from Omsk do not know!

I don't know about the men from Omsk. But the fact that you are "not in the subject" is obvious.

Why know something! "Guys from Omsk" - means the Omsk Research Institute of Instrument Engineering, which is part of the Ruselectronics holding. They are doing some kind of delirium, you know!

Similarly!

Nonsense.

Apparently, another non-existent analogue in the world of new physical principles))) The antenna of anti-aircraft radiation was described by Eisenberg. And used even in civilian life. NVIS or AZI as you like more))

[KJIETyc]

What ships will they put on? on the MRK?

[Avior]

RTO ocean zone sounds a lot :)

[Pacifist with AK]

It is difficult to call a new development. NVIS antennas have been used for quite some time. However, the news is good.

[fk7777777]

Maybe, but for 800 km by communication, these clunkers will not send.

[Avior]

Well forgotten old from my army youth?

[fk7777777]

Something I doubt very much that you will sail far away on this in the far sea zone, or ocean.

[Carib]

Fake news for foreign spies. Well, let them rack their brains, why do we need it ... ZI antennas have been known for a long time; P - some had such an armored personnel carrier, nevertheless, they didn’t support communication on the HF, or they didn’t set tasks (for example, why not shine), either the crew’s skill wasn’t ... I was repairing the connection, but in the ZAS car, I didn’t have permission then they didn’t let me in ..

This is news for our leadership from the category "we are atat, and we are getting stronger." Those. financially cut new developments, but we still create unparalleled in the world.
And now a very interesting stage is beginning. They have developed something (which the Defense Ministry is sprightly broadcasting), and in the series it is necessary to introduce and cure childhood diseases that all new products have.
It’s only because of the reduction in funding that people are starting to run (I’m witnessing this in my sphere) and what of those new developments will be able to bring to mind those who have remained incomprehensible.
Perhaps some of the interesting developments due to the lack of specialists can go into the scrap at the stage of trial operation.
