Otherworldly Conquest Manual
Chapter 329
In the reception hall.
I heard what Yang Boli said.
Ma Ning's face remained unchanged, but his heart was cold:
The main play is coming.
Although the rabbits have reached a preliminary trade agreement with the Yang family, the word "preliminary" is enough to explain everything.
These days, anything can happen before things are completely implemented.
For example, a relegation team in the Premier League scored nine negative goals in three rounds.
At the beginning, Higuain entered the physical examination room. As a result, two hours later, the small cigarette gun unexpectedly appeared and signed with Naples.
Say a bad word.
If Yang Boli is in a bad mood because of hemorrhoids and cancels the transaction - no matter what the consequences will be if this happens, at least the floating array will not be available in a short time.
Therefore, Ma Ning's attitude towards the transaction is quite solemn, for fear of any accident.
He carefully took down two space bags from his body and put them on the table:
"Shopkeeper Yang, master Yang.
These two space bags contain the core array of our ancestral communication devices.
By the way, I mentioned it with shopkeeper Yang.
This array has a large volume and needs to be placed in a wide and safe area. I don't know shopkeeper Yang...... "
When Yang Boli heard the speech, he immediately answered:
"The venue is ready. It's in the clan land not far from the side of the reception hall."
Then he quickly looked at the leftovers on the table and asked tentatively:
"If shopkeeper Ma doesn't feel tired, how about we deliver the goods now?
By the way, other items we deal in are ready and can be handed over to you at any time. "
Ma Ning kept his expression unchanged and scolded the old fox in his heart.
Naturally, he would not believe the second half of Yang Boli's words.
Before verifying the effect of floating array, the other party will not trust to give the array to himself.
In addition, Ma Ning is not so low. The chamber of commerce takes the initiative to ask for compensation first. This behavior is similar to lifting the table.
Yang Boli's way of doing this is that you won't open your mouth after eating. You have both face and lining. However, it makes you feel quite bright. Your level is much higher than that of Tang Si.
However, although the second half of Yang Boli's words can't be believed, the previous proposal is still very valuable, which can be said to hit Ma Ning's heart.
So he accepted Yang Boli's proposal:
"Please, master. How dare I refuse? Please ask shopkeeper yang to lead the way."
Then a group of people walked through the courtyard and Yang Boli introduced them as he walked.
Finally came to an extremely open area.
The size of this area is almost 200m x 200m, surrounded by several warehouse like houses and no high-rise buildings.
It seems that it should be a warehouse in a good location that is not particularly important.
When we get to the center of the field.
Ma Ning handed the two space bags to Wei Qiangsheng, who showed his mind and took out dozens of wooden containers.
Then he looked at a middle-aged man around him and said in Chinese:
"Huang Gong, please follow the plan."
The middle-aged man looked solemn, touched the calluses on his hands and said:
"I see!"
The middle-aged man called Huang Gong is Huang Jiaqi, from a large Tianyan project center in Southern Guizhou and one of the participants of tianqin project.
In addition, he is also the chief engineer responsible for the installation of antenna array.
Mentioned earlier.
The effective distance of the antenna array agreed by the rabbits and the Yang family is 750 km, while the transmission distance of the active antenna array is generally more than 6000 km.
The 2500 km antenna array found by rabbits from jiaoao was small, let alone the 750 km "mini" model.
So this time, the rabbits had to go to the war readiness warehouse to look for the inventory of the previous generation, and finally locked the antique with a transmission distance of 830 kilometers.
Considering that there is no radio interference in Da Mo Jie, the limit distance of this equipment in Da Mo Jie may even reach 900 km.
I made money for Ziqiong city again, damn it.
Previously, it was well known that children's shoes had raised a problem that the power of the antenna array could not transmit video.
Here's a question:
Strictly speaking, antenna array, antenna array, array antenna and array antenna are four different concepts.
Are you dizzy?
That's right. That's how this thing burns your brain.
Although at present, most of the above four words actually refer to the same things, even many radio professionals can't distinguish these things.
However, under certain circumstances, these concepts are slightly different.
Among them, the antenna array is a large equipment belonging to the quasi celestial eye level, or most of the time, the media will directly call it the celestial eye.
As we all know, the students calculate the antenna array.
Large scale antenna array is a natural extension of MIMO technology. By increasing the number of original transmitting side antennas by an order of magnitude, such as 64 and 128, the transmission efficiency is improved.
The antenna array is more sophisticated. It is a large non cluster device, involving Hertz vector.
The bandwidth of this device is very easy to transmit long wave, and many transoceanic communications rely on long wave.
For example, the e765 that rabbits had previously shipped from jiaoao is a typical representative.
Students who don't understand why this thing is in jiaoao can think about what ocean fishing boat center there is in jiaoao.
The antique model found by the rabbits this time is not confidential. In short, it is a rod antenna.
The basic structure of this antenna is two identical half wave dipoles placed at right angles to each other and fed in phase.
This is also an array closest to the array concept:
It can improve the gain by stacking multiple rod wound antennas along the vertical axis. This structure is called stacked array.
The working modes of rod wound antenna are divided into normal and axial, and the polarization mode is different under different working modes.
In normal mode.
The antenna radiation wave is horizontally polarized, and the polarization direction is perpendicular to the antenna axis.
In axial mode.
The radiation wave is a circularly polarized wave around the antenna axis.
This mode is actually a technology two generations or a generation and a half ago. At present, most of the antenna technologies use active types such as log period or end fire.
However, although this technology is relatively old, it is better than robustness.
Even if its transmission distance can reach 900 kilometers, it is still not as mobile as modern antennas.
But in its transmission range, it is almost like a defense tower.
Ziqiongcheng is obviously a long-term meal ticket... Cough, long-term partner.
So the rabbits did not intend to pit Yang Boli and others in this regard.
This is also the consistent style of rabbits. I may make money, but you will never lose.
Like I said before.
Although the floating array is valuable, the value of communication technology to Ziqiong city is countless times higher.
Even if the rabbits developed Star Trek technology by studying the array in the future, Yang Boli and they did not lose any money.
So strictly speaking, this trade should be three wins:
The rabbits won twice and Ziqiong city won once.
Look back.
Although the previous generation antenna array from a reserve warehouse in Southern Guizhou is not as good as many modern generations, it is really not small and covers an area of more than 10000 square kilometers.
Otherwise, the headquarters will not arrange nearly 100 technicians to assemble it.
Therefore, considering that assembly may take two to three days.
Huang Jiaqi and others first assembled a small base station with a communication range of 30 kilometers and gave it to zibaoxuan's people to get used to the operation.
Ma Ning found Yang Boli and took out Mo Peidong's invalid gold pill
