What is the method to make a homemade wifi external antenna? Is the operation process simple?

Introduction: Mobile phones are inseparable from antennas, but now designers are becoming more and more advanced, using new technologies to hide the antennas in mobile phones, which are built-in antennas. But when it comes to antenna issues, it is undeniable that external antennas have better signals than built-in antennas. So many netizens want to make their own wifi external antenna, so how to make and install it? The above is an introduction to the method, and the whole process is actually relatively simple.

1. Elementary modification

Take the 3G card as an example. The new one must have a shelf life. If there is any problem if you take it apart at this time, it will be difficult to repair it later. So how can we improve the signal without damaging the 3G network card? By modifying the wireless network card, we can actually make a wifi external antenna. Take a can and cut it open and use the USB cable. Connect to the online class and connect the other end to the can.

2. Intermediate modification

Using cans to make an external WiFi antenna looks like a toy for children, and it doesn’t look good at all. Then I can look at another antenna that is modified through an aluminum alloy pot cover. The middle of the pot lid can just fit through the hole for the USB extension cable, and then the back is fixed with plexiglass and long screws to prevent it from shaking. Such an antenna looks very beautiful, and has a better signal than a can, and the production method is also quite complicated.

After using the homemade wifi external antenna method introduced to you in the above text, have you found that the signal of the mobile phone has become better? In addition, the power consumption of the mobile phone has also become lower, and the mobile phone is more durable. After learning the above method, you no longer have to worry about being in bed without a signal.
