A large number of people today, due to the growing popularity of the Internet, are increasingly asking questions about how to increase its power. High speed access is possible only in those places where there is a maximum signal level. In the event that it is weak in your area, then the page loading will take a long time. To solve this problem, you can use an external antenna.
The most popular are the following types of home-made devices: made from a can, Kharchenko's antenna and a contactless adapter. It should be understood that it is necessary to increase not the number of percentages or decibels, but increase the speed if a 3G modem is connected.
Also, the simplest version of such a device can be made using copper wire. For example, if you wind three or four turns on the end of the modem, where the built-in antenna is located, then the speed can be dramatically increased. But this solution requires increased accuracy and skill, because for each device it is necessary to select a certain number of turns.
One of the mostA simple way to increase speed is the Kharchenko antenna for a 3G modem. In this case, you can create a fairly simple and effective design. It consists of two elements having the shape of a square. This antenna is designed for a frequency of approximately 2100 MHz. To achieve such a result, the following characteristics should be borne in mind: the wavelength reaches 143 millimeters, the sides of the frame - 53 mm. The copper wire, which is approximately four millimeters thick, must be bent. In this case, Kharchenko's antenna will create the desired effect.
It is also necessary to strictly observe all sizes. In order for the resistance inside to be reduced, special diamond-shaped elements should be made. The internal corners of such parts should reach approximately 120 degrees. After the Kharchenko antenna takes on the proper form, a special cable should be connected. To increase the effectiveness of the device, it should be equipped with such a detail as a reflector. The resulting structure is eventually soldered to the antenna.
Let's explain that the reflector is a metal plate, which is created using foil textolite. This element should not be attached directly to the antenna. Between them there should be a distance of about 36 millimeters. And finally, Kharchenko's antenna must be connected to the modem. As you know, this device does not have special connectors required for such devices, so the wires from the latter should be wrapped around the 3G device and secured withwire.
There are a lot of similar devices, almost all of them are able to increase the speed of a 3G modem. The Kharchenko antenna is the simplest, but at the same time quite effective way to achieve this goal. In addition, it is very easy to build it, without having special knowledge and skills, which means that this design is available to literally everyone.
