Antenna Kharchenko. Creation and recommendations

A large number of people today,in view of the growing popularity of the Internet, is increasingly asking questions about how to increase its power. High speed of access is possible only in those places where the maximum signal level is present. In the event that in the territory of your locality it is weak, then the loading of the pages will take place long enough. To solve this problem, you can use an external antenna.

The most popular are the following specieshomemade 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 percent or decibels, but increase the speed in case of connecting a 3G modem.

Also the simplest version of such a devicecan be done with copper wire. For example, if you wind at the end of the modem, where the built-in antenna is located, three or four turns, 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 easiest ways to increasespeed is the antenna Kharchenko for 3G-modem. In this case, you can create a fairly simple and effective design. It is two elements that have the form of a square. This antenna is calculated for a frequency of approximately 2100 MHz. To achieve this result, one should keep in mind such characteristics: the wavelength reaches 143 millimeters, the sides of the frame 53 mm. A copper wire, the thickness of which is approximately four millimeters, must be curved. In this case, the antenna Kharchenko will create the desired effect.

Also it is necessary to strictly observe all dimensions. In order to reduce the resistance inside, it is necessary to make special elements in the form of a diamond. The internal angles of such parts should reach about 120 degrees. After the antenna of Harchenko has acquired a proper appearance, you should connect a special cable. To increase the efficiency of the device, it should be provided with a detail such as a reflector. All the resulting design is eventually soldered to the antenna.

Let us explain that the reflector is ametal plate, which is used to create a foil-shaped textolite. Directly on the antenna, this element should not be fastened. Between them should be a distance of about 36 millimeters. And, finally, Kharchenko's antenna should be connected to the modem. As you know, this device does not have the special connectors required for such devices, so the wires from the latter should be wrapped around the 3G device and secured with wire.

There are a lot of similar adaptations, practicallyall of which can increase the speed of the 3G modem. The Kharchenko antenna is the simplest, but at the same time, quite effective method for achieving this goal. In addition, it is very easy to build without having special knowledge and skills, which means that this design is available to everyone literally.
