Radio Band Chart
The cell inhibition system was developed by military technologies in order to nullify the enemy's communications, today extends to civil matters. The cell blockers, using modern signal processing technique to interfere with the connection between cell phones and cell tower with which you are communicating on an ongoing basis. radio band chart frequency waves emitted at low power, which block cellular communications in different ranges depending on the cell block power and geographical location within the cellular network. These systems are also known by the name of blocker, jammer, Nullifier, override, wireless communications neutralizer. When activated, the cell completely lost the connection to the tower and depending on the cell and its technology will be displayed "no service", "No Network" or the screen remains normal but may not issue or receive any communication or text message within inhibition area. All incoming calls from entering directly to voicemail as if the cells were found in an area unreachable. It generates a triangular wave can be adjusted using an IC operational 1458, this triangular sign you add white noise, which you can generate with a LM386, mixing and throughout a FET, injects an RF Amp, working in 1. 30 to 1. 39 GHz frequency, making use of harmonics that occur, the bandwidth will be even greater. The antenna should be short, set the frequency, the connections must also be short and should be assembled in a FIBERGLASS card, do not use bakelite to these frequencies as the signal spreads travez it. The list of components is not required, the diagram explains it all, you must have experience in RF circuit that works for you, use the radio band chart by downloading it from Mediafire, the picture you put here is of low resolution and is for reference only. This is a commercial Jammer, the diagram that post, will let you make one that works well, but not with that aspect. . Or maybe if you try. This circuit works, the diagram has no errors, the power is 80 mWatts, which will get a range of 30 meters around, if the antenna is well calculated. The frequency accuracy depends on the tolerance of the components. This team works for GSM1900 type used in North America and some countries of South America. Find the frequencies of the first cellular carrier in your country before starting this project. . . .
