Laptop equipped with an antenna. A rare sight. Built-in WiFi antenna hidden inside, does not easily accessible. Constructed on the principle of saving space, can have a complex configuration in order to optimize use of a laptop volume. We believe products are designed using special simulation software, customized for the needs of notebook models made inseparable from the e-filling. Redo is not possible at home. Antenna for WiFi laptop today different versions ...
Antenna for WiFi laptop without n-Connector
- The characteristic impedance of 50 ohms.
- N-connector.
These are now standard WiFi-antenna. Laptop devoid of external nests under the device, internet want to catch. USB-adapter in the form of flash today no surprise. Raskurochivayut attach an external antenna, it said in a review. Straightforward solution. Take, severing internal antenna to attach a seat homemade or purchased from an external high-gain, sometimes active type.
WiFi Bridge Senao 2.4 GHz running the client. Can settle on a steep mast is set on the table, ensuring reliable reception of the signal relay. As I understand, something like directional access point of 2.4 GHz (available and the device 5 GHz), simply relays the signal provider. Can by means of two devices to establish a "bridge" between the points at a distance of several kilometers. WiFi-antenna laptop is placed on the USB port, after podgruzki driver will take the network a given direction. Available function works as a WiFi client.
The device is not positioned antenna has a large gain, will allow easier to tune to the provider, rather than using the built-in antenna. A modem equipped with a powerful technique. The operating principle of a similar, larger settings. Please note, the device is specifically designed all-weather, the user decides whether to pull the RK 50 cable to the roof, satisfied room setting.
Inside the active chip, we believe there is present the amplifier, reducing the cable length is not critical in ensuring signal reception. Work is proceeding in the figure. An antenna with a reflector inside the block, advanced amateurs can collect if desired. USB modems as a flash opened, the box even more so succumb.
The internal antenna is fitted to a standard connector. The device is massive enough, the way the world - a bulky antenna ceteris paribus always work best miniature. device cost is over and above 1200 rubles.
Senao brand shop represented Radioport. Before us is directed to the client access point function. Allowed to take with a block, rather small (no more than a laptop). Radiated power up to 800 mW, may be detrimental to the health of people around them. Do not use the device at a mass gathering of people, when the internal antenna does not pull the laptop, WiFi bridge can improve matters.
Reflector-power flash WiFi modem signal
WiFi and cellular communications frequently occupy similar frequency when the shops filled reflectors resembling radar antenna for 3G modems, it became obvious that similar will soon come in handy wireless network protocols 802.11. REMO connect 2,4 aimed at the frequency 2.4 GHz. Principle: the focus of the reflector is placed ordinary modem memory stick protruding converter. Familiar with satellite TV understood the meaning of ideas. Because modem turned true antenna lobe for a notebook with strongly narrowed azimuth (elevation angle by a constant). The brain resists the payment of 1600 rubles for beautifully curved steel.
Apparatus completed disk with the software. Tend to think inside is a simple amplifier, lifting the limitation of the maximum length of wire. Bend in the image of the screen to ground and put the flash drive in the focus of everyone can. All you need to take a course in the theory of antennas to calculate the size and curvature of the parabola frequency of 2.4 GHz. Since the restriction of only being diagrams in azimuth, in the manufacture of complex devices can not see.
It is possible to bend arbitrarily large metal segment, our external antenna for notebook acquires high-gain focus. To manufacture will vulgaris foil, can be pasted on smoothly curved plastic sheet. The problem of limited extension flash search, the maximum length, which is often small, given the relatively low signal power USB transceivers.
Parabolic antenna for laptops
Range C captures the interval 4 - 8 GHz WiFi standard fall on 5 GHz. Allowed if the tower is far away, there is a clear line of sight, you can aim the dish. TV antenna Laptop will spravno.
Typically WiFi horizontal linear polarization. To consider when choosing a converter. In stores, there are irradiators 2.4 GHz. As for equipment intended fishing WiFi, like manufactured by Vector vector.kharkov.ua.
There are plates on both the WiFi standard, demonstrating a gain of 24 dB. Note: catch the signal will be hard, narrow beam pattern with no clear line of sight. The reception will be stunning. A case where the steppe people suffered weak signal, even at a distance of several tens of kilometers was in sight translates tower. We think, readers guessed how you can improve the reception.
The operating principle of WiFi-antenna parabolic type is similar to a satellite. The diagram is narrowed in elevation azimuth converter amplifies the signal. We get a great result, a variant suitable stationary basing. It remains to clean the device. It is possible to use equipment such as a satellite television receiver. One bad luck - 2.4 GHz spacecraft is not broadcast, although they may.
There is a chance of failure. The signal level is defined only polarization. TV receiver indifferent information encoded radiation. For example, pay-TV channels. He does not understand the taking, catching quality shows. the software will fit for WiFi.
Voltmeter thrust into the antenna wait. Special high-frequency models are expensive to scare away the man in the street. In an extreme case, coarse scale use notebook signal level. Vector Products designed for RC cable 50, provided with n-connectors, the computer does not votknesh, router amiss. However, as raskurochit laptop for external antenna, can be viewed on the Internet. The main thing is not to burn the receiver may not be designed for high power output by a plate. The question is how to connect the antenna to the laptop, leave it up to readers. We repeat, the direct method is not available. There are two possibilities:
- Kurochit housing, built-in antenna to seek input space (the wireless network adapter module).
- Use external receiver as a router, modem, bridge of the type described above.
It sounds absurd expression "antenna for a laptop with his own hands." Manufacturers do not give the user a chance to just take, plug plate, zigzag (biquadrate). However, we can try to tell you how to add a typical n-connector into the laptop. Feasible, although there is a risk of equipment damage. Homemade antenna for laptop used in tandem with a PCMCIA WiFi card. Just added to the reflector foil discussed above. It turns out "corner", with no bottom wall. Located outside of the PCMCIA adapter for WiFi. hand corner cut vertically at a 45 degree angle to the side faces laptop.
To fix a homemade device, enough to cut a piece of a plastic card, which would be inserted into the PCMCIA slot on the card. You can enhance the reception and the usual flash drive. Not necessarily immediately run to the store for a reflector facing 1600 rubles, which are described above. But homemade antenna for laptop in pure form has not yet invented, because there is no place to connect. If only through a special WiFi adapter. Curious looks device in the figure, but this is not the antenna. We are dealing here with a modem, which is complemented by external omnidirectional poluvibratorom.
How to connect
If you still want to connect the antenna, doable. Remove the back cover and locate the WiFi adapter card. You learn from the presence of the coaxial connector. Find the store the same, and through it connect or purchase homemade antenna. Including active. By placing the accessory on the roof, you will find some signal even visiting the polar bears. Show them the Belarusian advertising refrigerators ...
