Installing 3G Antennas for notebooks

This is for the only free mini PCI-E slot models, such models are also more common, especially in some international brands of models. With the mini pci-e slot, according to the method of the previous period to add 3G network card and mobile card slots, this time only need to install 3G antenna is done.

Buy Antennas as needed

The price of the notebook antenna is very cheap, the general double price will not exceed 10 yuan, everyone on Taobao using "Wwan antenna" keyword can easily search a lot of products. When you buy, you can choose 2 connectors or a single connector 3G network card antenna, connectors in the form of IPX connectors, not the desktop network card with the thread.

Traditional antenna: For the traditional 3G network card antenna, the most need to consider the problem is thickness. Now the top cover of the notebook is thinner, while the LCD screen to the top edge of the upper edges of the width is also getting narrower, so we need to check with the merchant before the purchase of data can be installed. However, according to the author's experience, there is also a thin film antenna in the market, that is, PCB printing antenna, also suitable for the 3G network card, the top cover too thin models can consider such products.

Detachable antenna: As the name suggests, compared with traditional antennas, no-disassembly antenna does not need to be installed in the top cover, its antenna cable to be shorter, the antenna of the oscillator through special design, generally relatively small or soft material, we can according to the need to put it in the notebook under the cover or the fuselage of any free place, And some products of the oscillator also with insulation design, do not worry about short-circuit, single root price in general around 10 yuan.

For this type of antenna recommended to buy a slightly longer cable products (compared to the cable-free antenna cable around 2cm length, the cable length of the traditional antenna is usually between the 45cm~80cm, because it can more flexibly arrange the placement of the antenna, such as placed in the vicinity of the 3G network card (this position is located under the PCB board , the signal will be weakened more clearly). If you want to get better signal strength, consider mounting on both sides of the shaft. In fact, many notebook WiFi antennas used this design, so that the PCB circuit board to avoid the shielding of the signal, for those who use all-metal top cover of the model can also circumvent the full metal cover shielding role, in this way upgrades can reduce the workload of dismantling, reduce risk.

Traditional antennas need to consider the thickness and height of the oscillator

The oscillator design of the free-disassembly antenna is relatively small, and it is in the form of a single

Now part of the market for the notebook antenna is also designed on the hinge sides of the edge position

Antenna installation is simple

For a detachable antenna, its installation method is very simple, here is no longer to repeat. However, in order to obtain better signal reception capabilities, if the top cover of the notebook used to meet the installation conditions and has been insured, it is recommended to choose a traditional antenna. The installation method is relatively easy, but more steps, involving the C shell and the dismantling of the top cover. Because in the previous series of "Computer" has been 5 consecutive period of the dismantling of the notebook body, so here the author will focus on the removal of the top cover and the installation of the antenna. The detailed operation steps are shown in the diagram.

First step: Remove the top cover border. Depending on the thickness of the top cover, some of the top cover's screen borders do not have a fixed screw, some will use some decorative pieces or damping rubber pads to block the screws. Use tools such as blades to pull off the decorations and remove all the screws around the border. Then use the hand to buckle the inside of the screen frame gradually exerting force, according to the top, both sides and bottom of the smooth gradual separation of the screen border.

Step Two: Detach the connection between the screen and the hinge. In order to facilitate the alignment of the screen and the top cover to separate, the screen shaft usually has one or more fixed screws, these screws are easy to find and disassemble, remove these screws and the top cover will be separated from the screen, just note that the removal of most of the screws after the need to use objects to hold the top cover, to prevent a single screw force because of the force too large damage to the top cover.

Step three: Install the antenna oscillator and walk the line. The details of the process of disassembly of the fuselage please use the mobile phone scan the upper right two-dimensional code or direct access link reading, here I focus on the installation of the antenna. If the cable is too long, antenna wiring We need to master a principle, from the top cover area to start installation, that is, the first installation of the antenna oscillator, and then the connector placed in the mini Pci-e slot near the other end of the connector along the mini pci-e slot line, presumably estimated the internal line of the fuselage required length Hide the extra antenna cables inside the top cover of the screen.

When installing the antenna, the antenna can be installed on the top or edge of the screen according to the actual situation. First rip off the back of the antenna, paste it on the inside of the top cover, for ultra-thin top-cover models, antenna cable may not pass through the screen and the gap between the top cover line, you can consider along the screen edge of the line. If the edges of the screen are narrower or if other cables are already positioned, two 3G antennas can also be considered from both sides, and from two rotating shafts to the inside of the fuselage respectively.

Install the 3G antenna and follow the existing cable-fixing device of the WiFi antenna.

Step Fourth: Wire the cable through the hinge. This step is an important step in the antenna installation process, if the installation of the problem caused by the installation of the screen frame is not in place or even notebook follow-up open and closing problems. Because different models are designed in different ways, the easiest way is to follow the existing screen or WiFi antenna line of the notebook line, at the same time according to the number of line space to choose left or right axis to go, so we need to buy a longer cable cable antenna. For model models, we will line the cable of a single 3G antenna along the back of the screen, and from the right through the rotating shaft, 2 90-degree transitions after the introduction of the fuselage (such as white Serpentine line).

Pass the antenna cable around the hinge and follow the line of the white Serpentine Line

Fifth step: Fixed and install the antenna. At this time the antenna cable wiring work has been completed, with plastic tape will be fixed to the antenna, and timely back to install notebooks.
