"I've seen it from magazine articles. Duan Yun prevaricated casually.

"But this kind of antenna is not very easy to use in our place, right?" Li Guosheng put his finger on the glasses on the bridge of his nose, and then said: "Chief Engineer Liu of our factory brought a kind of Yagi antenna from the south, I went to his house to see it, and I still can only receive two units, but the clarity of the provincial station is a little higher......

"My antenna is not the same as the southern one, and I have redesigned the amplifier part. Duan Yun replied.

"Hehe......" Li Guosheng smiled when he heard this, but a look of disapproval flashed on his face.

At this time, Yun had already begun to recheck the antenna in his hand.

In Duan Yun's opinion, even if his antenna is not as easy to use as expected, it is absolutely impossible to be worse than the effect of the lever antenna on this TV set before, and the current situation is that Li Yun's TV is a little unclear even the signal of the central one.

And when Duan Yun opened the white iron shell wrapped around the amplifier circuit board, he immediately understood the problem.

It turned out that at this time, the two solder points of the circuit board and the feeder were disconnected, and it was estimated that Duan Yuntin was a little careless when soldering, and the solder wrapped the copper wire too little, and the wire head was repeatedly bent during transportation and there was friction with the outlet of the white iron sheet, which eventually led to the copper wire joint being broken.

This also allowed Duan Yun to gain a little experience, that is, in order to put the wire head and the exit of the shell, it is necessary to add a layer of protection to prevent wear and tear from causing disconnection or leakage.

Duan Yun took out the soldering iron and solder rosin he had with him, and began to re-solder the joint.

After the soldering was completed, Duan Yun carefully wrapped the joint part in two layers with insulating tape to prevent the copper wire from being broken again.

After doing all this, Duan Yun finally breathed a sigh of relief and stood up.

"Xiao Duan, let's eat at my house in the evening. Li Guosheng said to Duan Yun.

"No need......" Duan Yun smiled and shook his head.

"It's okay Brother Duan, you help my house install wires, how can there be any reason to let you help in vain, besides, you and my parents are both from the same factory, what is it to have a meal together. Li Yun on the side said.

"Ah, well. Duan Yun didn't pretend anymore when he heard this, and responded casually.

"Wife, heat up a few more steamed buns, and eat at our house for a short night. Li Guosheng shouted into the kitchen.

Picking up the antenna, Duan Yun walked to the window again.

"Try a different channel. After Duan Yun leaned his hand out of the window, he commanded Li Yun.

"Click!"

As soon as Li Yun turned to the channel of Central One, the picture flashed first, and then a clear picture appeared.

"This ...... That's all too clear......"

Seeing that the TV picture of the Central One at this time was much clearer than usual, Li Guosheng and Li Yun's father and daughter were taken aback, they actually didn't think that Duan Yun's homemade antenna would work at all just now.

But what surprised them even more was to come.

"Click. As Li Yun turned the knob again, two more pictures of cross talk in coats appeared on the TV screen.

"Jiang Kun, Li Wenhua!" Li Guosheng recognized these two of his favorite cross talk actors at a glance, and his expression was a little excited.

"It's ...... Henan TV?" Li Yun on the side had sharp eyes, and immediately saw the station logo in the upper left corner, and then said excitedly: "This is the first time that our family has received a program from Henan TV." ”

"Wife, fry another meat dish and put more oil!"

Li Guosheng shouted again into the kitchen, and said to his daughter expectantly: "Try another one!"

"Click!" With a soft sound, the TV screen changed to the cartoon "Little Tadpole Looking for Mother", and the station logo became the provincial Taishan West Station.

"Shanxi Taiwan has also become so clear!" Li Guosheng's expression became more and more pleasantly surprised.

"Change ...... again"

"Click!"

Li Yun kept flipping the knob to change the channel, and after a few snowflakes in succession, two more provincial channels appeared on the TV.

Now it is possible to receive six TV stations, two of which are barely watchable, although the definition is not high.

Li Shengguo's eyes were already a little surprised when he looked at Duan Yun again.

"Dad, this station is playing "Volleyball Girl", and I have long wanted to watch this TV series. After Li Yun turned the knob back to the channel where she was acting in the TV series, she never dialed it back again.

"Go downstairs and buy a bottle of Lao Baifen for Dad!"

Li Shengguo said, took out a five-yuan bill from his pocket and handed it to his daughter.

"Dad, you drink less alcohol, didn't the doctor say that your blood pressure was a little high last time?" Li Yun didn't mean to reach out and take the money.

"Isn't there a guest at home? Xiao Duan has been busy for a long time, drink some wine to relieve fatigue. Li Guosheng said seriously.

"Come less! You're just making excuses!" Li Yun saw through his father's mind at a glance, and didn't give his father any face.

"With the rest of the money, you can buy bubble gum and waffle cakes, don't you like to eat this thing the most?" Li Guosheng said with a smile.

"Wait!"

Li Yun smiled when she heard this, took the banknote from her father's hand, turned around and left the room.

"The female university is not in the middle of the ......" Li Guosheng pursed his lips and muttered to himself, turned around and tuned the TV to the Henan station where Jiang Kun's cross talk was played.

After Duan Yun saw that the clarity of the TV picture was about the same, he directly used the hand drill and angle iron he brought to punch holes and install a simple shelf by the window, and fixed the antenna on it.

In fact, Duan Yun installed this antenna in the wrong way, but now the roof can't go up easily, and the line brought by Duan Yun is not long enough, so he can only temporarily adapt to local conditions and install the antenna outside the window.

"Uncle Li, if the TV signal is not clear in the future, you will shake the antenna outside, if it still doesn't work, install the antenna on the roof, this is the first time I have installed, I don't have all the materials and tools at hand, so I can only install it outside the window first, at least it is convenient to adjust......" Duan Yun patted the dust on his hands, and said to Li Guosheng with a smile.

"That's good,The chief engineer's TV can only receive two,You can receive 6 antennas,This technology is too powerful。 Li Shengguo praised Duan Yun with a smile on his face.

Li Guosheng really admired Duan Yun a little, he would never have thought that there was a master of this kind of electronic technology in the factory anyway, this was the first time he had met such a young man in the factory for more than ten years.

"Xiao Duan, hurry to the kitchen to get soap and wash your hands, and eat immediately. After Li Yun's mother saw that the TV signal at home was much clearer, her face turned into a flower and greeted her repeatedly.

"Hey. After Duan Yun answered, he put away his tools and walked to the kitchen.

And at this time, Li Yun also came back from buying wine, still chewing a bubble gum in her mouth......
