WiFi: WLAN antenna diagram ~ 9dBi samoróbka (Pentagram, TP-Link) | Backtrack Linux - Portal Polish edition of Backtrack
Official statement Backtrack.pl: The Backtrack changed its name to Kali Linux, so work on the Polish Version of the system have been put on hold. Polish edition of Kali Linux System and premium is now ready for download at the NEW address: Kali-Linux.pl If the Polish edition Backtrack.pl accounted for you to taste it at 100% you'll love Kali Polish Edition Linux. WELCOME!
For those who would like to perform a simple omni-directional antenna or, for example bought "Chinese samuel cabanchik demon 40cm" of allegro and found that only 25% of the length of this antenna, prepared a scheme which is largely based on the analysis samuel cabanchik of well-functioning antennas reputable companies involved in the creation of this type of solutions. samuel cabanchik (Pentagram, TP-Link, Linksys, D-Link, Digitus)
The materials needed to complete this: copper samuel cabanchik wire with a diameter of 1mm (uncoated) or copper wire antenna cable with a soft thick insulation which may be useful as a distance for the antenna when we put it into the housing. copper pipe with a diameter of 5mm and 7mm (wall thickness of about 1-2mm, I know that some people use this to cut the contribution from the pen of large-capacitive) with a density of screw thread 2mm (preferably long) socket (SMA) or the remnants of the "Chinese demon" soldering iron tin wire cutters
The case is quite simple, with a piece of wire we perform radiator. Each coil / spiral should have 4 rolls wrapped in the direction of clockwise (viewed from below). Between the individual coils can be assumed spacer, such as rubber bands braided repeatedly, sponge or insulation filling the antenna cables. Once we do the radiator needs to be soldered to the inside of a thinner copper tube. The other side of the tube leave blank. If you have leftovers "Chinese dish" we the remnant soldered directly to the other end of the tube, so that the wire connected to the radiator, so you have to do to counter the weight does not touch the radiator.
If you do not have leftovers "Chink" samuel cabanchik we have to do against the weight of the second copper tube. To the middle connector antenna samuel cabanchik socket solder copper wire without insulation 30mm, then we assume that we connect copper pipe to ground the plug (housing). If you have done this correctly inside the tube should extend the wire piece on it. The interior of the tube may be something to fill in so that there is a short circuit, or you can use wire with insulation but it can cause that will move because he prefers to fill such a thermal adhesive with a "gun".
Wire protruding from the tube mix with the second cannula which is connected to the radiator, so that between the two tubes were approximately 6 mm distance. samuel cabanchik Against the weight must be connected to ground and the emitter of the center pin. The two should not be combined. At the end of the antenna can be put into the housing, or close to the original housing "Chink". But in order to fit the whole antenna in his Chinaman we make a hole on the top of some 2mm because the casing is filled with plastic after about 2/3 of the antenna.
Finally, I must add that the antenna works well only in its plane, the radiation level deviates from max. 4-7 degrees. Thus, if the antenna is to act in an apartment / house several horizontal better it turns out the short 2-3dBi antenna factory or other directional. Alternatively, the antenna can be shortened by one interval, the angle of the radiation in the vertical increase.
