Chapter 34 Installing the Antenna
At 06:30 in the evening, Duan Yun took the antenna he made to the third living area by bicycle.

After knocking on the door twice, Duan Yun explained his intention, and the door was quickly opened.

To Duan Yun's surprise, the person who opened the door this time was a pretty girl with fair skin.

"You...you're Xiaofang's brother, right?" the girl asked after sizing Duan Yun up and down.

"Yeah." Duan Yun nodded.

"Come in." The girl smiled and motioned for Duan Yun to enter the door, and then introduced herself: "I'm Xiaofang's classmate Li Yun, what should I call you?"

"My name is Duan Yun, you can just call me Xiao Duan." Duan Yun said with a smile.

"You're Xiaofang's brother, older than me, so I'll call you Duan." Li Yun smiled, and then called to the kitchen, "Mom, you're a guest, don't be busy yet!"

"Xiao Duan is here." Li Yun's mother came out of the kitchen. She wiped her apron with her wet hands and greeted, "Xiao Duan, go and sit at home, and I'll cut some apples for you..."

"Auntie, don't be too busy, I just want to see how the antenna installed for your home works." Duan Yun said, and walked into the inner room with the antenna.

At this time, there was a folding dining table in front of the window of the room, and it was full of books. Obviously, Li Yun was doing her homework just now.

"Wait a minute, it's a little messy, I'll fix it right away." Li Yun said embarrassedly when she saw this.

"It's okay, don't worry." Duan Yun smiled when he heard the words, and subconsciously glanced at the books that Li Yun put on the table. They were all textbooks for high school tuition. The handwriting on the books looked pretty and neat. Even more serious than his sister Duan Yun.

But soon, Duan Yun turned his attention to the 12-inch black and white TV on the trunk.

TVs in the past two years have not yet had flat-panel displays. They are basically convex screens. There are two control knobs next to the screen.

In addition, at the bottom is a tapered knob that adjusts the volume, which looks a little weird.

As for the TV antenna, it is a telescopic rod antenna that can be retracted and hidden behind the TV.

After thinking for a while, Duan Yun took out the screwdriver and vise from the tool bag he was carrying, and prepared to connect the antenna.

Duan Yun reserved a nearly six-meter-long feeder this time.

The feeder is the signal line connecting the early TV and the outdoor antenna.
The TV antenna feeder of later generations is a coaxial cable, and the feeder of this year is generally flat and double-wired, the wire body is insulating plastic, there is no shielding layer on the outside, and the anti-interference ability is extremely poor, and its performance when used outdoors will be affected by rainy weather. .

But this is already the best antenna material Duan Yun can find right now.

"Xiao Duan, you have to be careful..." Li Yun's mother on the side said worriedly when she saw Duan Yun was dismantling the antenna behind the TV.

"Mom, Brother Duan is very skilled. He has helped many of our classmates refit radios. The signal is good. Repairing our TV is a piece of cake." Li Yun Bingxue was smart and immediately heard that her mother was afraid. Duan Yun broke the TV, so he said to Duan Yun next to him.

"Don't worry, Auntie, just change the antenna. If the TV breaks, I will accompany you to get a new one!" Duan Yun turned his head and said with a smile.

"I'm just afraid that you will get an electric shock..." Li Yun's mother's expression softened when she heard the words.

Duan Yun used a screwdriver and pliers to connect the two ends of the feeder cable to the antenna end behind the TV, then wound the feeder cable from the back of the trunk, and then took the Yagi antenna to the window.

Generally speaking, it is better to place this kind of antenna directly in the open space on the roof, but due to the current conditions, Duan Yun can only temporarily install it in the position of the window to test it first.

"Turn on the TV to see." Duan Yun stood at the window and turned to Li Yun who was standing behind him.

"Yeah." Li Yun replied, walked to the TV, turned on the power, glanced at Duan Yun, and then turned the TV switch.

"Click!" After a soft sound, the screen instantly lit up.

"How is it?" Li Yun's mother heard the sound of turning on the TV, and immediately walked over from the kitchen.

"Swish..."

Snowflakes on the TV screen.

Li Yun twisted a few more tables, without exception, all snowflakes.

Seeing this scene, Li Yun's mother showed disappointment on her face. After seeing that there was no signal after changing several channels, she walked away with a sullen face.

"I'll adjust it again." Duan Yun frowned when he saw this, and then retracted the antenna that was peeking out of the window.

"Kaka." At this moment, the sound of the key opening the door rang from outside the house.

The door was pushed open, and a middle-aged man in a tunic suit and a pair of black-rimmed glasses walked in.

"Dad!" Li Yun turned her head and greeted him when she saw the man's face with joy.

"Ah... this is..." The middle-aged man asked suspiciously after seeing Duan Yun standing by the window.

"Dad, his name is Duan Yun, he is the brother of my classmate Duan Fang." Li Yun pointed to the vertical radio standing by the bed and said, "He repaired our radio before."

"Uh..." The middle-aged man's expression softened after hearing this.

"This is my dad Li Guosheng. He is the director of the supply and marketing department in the factory. He travels a lot. If you have anything you want in the future, just talk to my dad." Li Yun said to Duan Yun with a smile.

"Hello, uncle." Duan Yun quickly greeted politely when he heard the words.

"You are also from our factory?" Li Guosheng asked casually, seeing Duan Yun for the first time.

"I'm a lathe worker in a workshop, and it's been less than a month since I joined the factory." Duan Yun replied.

"Is that so, I said, how come you look so good." Li Guosheng smiled, pointed at the antenna held by Duan Yun, and asked, "You are..."

"The last time I repaired the radio, I promised to install an antenna for your house for free. I just made it today." Duan Yun said with a smile.

"Uh, TV antenna?" Li Guosheng became interested when he heard the words, and then took a look at the antenna in Duan Yun's hand, and said, "I think I saw your antenna when I was on a business trip to Guangdong, and the people there seem to be Is it called a fishbone antenna?"

"Uncle Li, you are really well-informed." Duan Yun was slightly surprised when he heard this. He also didn't expect Li Guosheng to call out the name of this antenna.

"My dad travels a lot on business and has been to many places." Li Yun was obviously proud of her father.

"I heard that this thing looks simple, but it's not very easy to do. It needs some electronic technology. In the south, it is usually made by a small workshop in a specialized hardware store. I haven't heard of anyone here who can do it. This kind of thing..." Li Guosheng looked at Duan Yun with some doubts, he obviously didn't believe that Duan Yun could have this kind of ability.

After all, he came to this gear factory after graduating from technical secondary school. He knows the level of education of ordinary workers in the factory, not to mention a lathe worker like him, even some old electricians in the factory have a very high level of radio. In general, at most, you can understand some simple circuit diagrams, and you can't make a TV antenna at all.
