Chapter 404

When it comes to reflectors and deflectors, some readers must have thought of something.

you 're right.

It's Yagi antenna!

Single or non single dog friends who sold in the 1980s and 1990s may have a little impression of a device:

It's a fishbone device.

It looks like a clothes hanger. A stronger one can also be used as a clothes hanger.

It is mainly mounted on the roof for receiving TV signals.

This kind of antenna is Yagi antenna.

It is a standard end fire antenna composed of an active oscillator, a passive reflector and several passive deflectors.

However, the name of Yagi does not mean that it is composed of eight antennas.

But because its inventor is called AKI xiuci:

This antenna was developed by AKI xiuci and his student Yutian Taiying.

So the full name is also called Yagi Yutian antenna.

Yagi xiuci.

His race can be seen from his name.

He was born in 1881 and died in 1976.

However, unlike those compatriots who bark, AKI xiuci is a very solid anti war faction.

He has been punished many times for publicizing anti war remarks, and even lost his professorship.

in addition to.

Yagi xiuci's position in history is also very, very special.

It belongs to the kind of situation where the layman knows nothing but the expert looks at it with his eyelids straight.

It can be said that:

If anyone can turn the tide of World War II, AKI Xiuji is one of them.

He once discovered the theoretical and technical structure of "high frequency guided antenna", which is a core technology for manufacturing high-performance radar.

So he submitted his paper and applied for a patent.

And promote the application of technology to relevant parties.

But unfortunately.

The invention did not attract the attention of neon.

Therefore, Yagi xiuci had to be sad, carry the paper patent, and transfer from Asia to Europe and America.

Clinker, Yagi's antenna technology has aroused great interest in John Niu and eagle.

And soon entered the actual combat application, invented the military radar for ships and aircraft.

So an interesting scene happened:

During the midway naval battle, the neon aircraft carrier was not equipped with radar.

The way they observe Eagle aircraft is the eyes of the lookout.

However, it happened that

The sea area of Midway was still cloudy that day.

When the eagle's dive bombers flew over the Japanese, the lookout saw them.

By this time, it was too late.

In just five minutes.

Three aircraft carriers, Chicheng, Jiahe and Canglong, were hit by bombs.

This so-called "five minutes of fate" has become a turning point in the whole Pacific War.

After the disastrous defeat in midway, in fact, the neon Navy still has considerable strength and can despise the army red deer.

But in the battle of Guadalcanal, the neon navy was badly weakened in the war of attrition.

Among them, a very important factor is radar.

The core technology mastered by neon people is used by the enemy to fight against themselves.

But I still know nothing.

This is really a great anecdote and scandal of World War II.

Later, neon forcibly recruited Yagi xiuci into the Research Institute and asked him to be responsible for the research of RF weapons.

Then the big man did bosao operation again:

The first is not to work.

Yes, of course.

This may also be that his ability is indeed limited.

In short, there was no achievement until GG base was pushed.

in addition to.......

He also made six lab colleagues red.

Well, it's red.

Three of them later went to the hairy bear and participated in the radar research of MIG series.

Therefore, Yagi antenna, whether it is itself or its inventor, has a quite legendary story.

The topic returns to its original place.

The advantage of this antenna is simple combination, but it can achieve high directivity.

If you smoke, you can make it directly from the tin foil in the cigarette box, or other metals.

It belongs to a very practical equipment.

"It is obvious that the Tianjie of Da Mo world adopts this highly practical connection principle."

At the scene of the robbery, I'll tell you in advance if you Gu. This book hasn't Gu once since it was opened. This character can still be trusted
