Cell phone jammer at site with the instruction of installation training document

cell phone jammer    can be installed on various places according to the installation specification requirements, including the wall, ceiling and so on. The use of high-frequency skin effect can prevent the penetration of electromagnetic waves made a good conductor and electromagnetic shielding devices, in order to meet the electromagnetic compatibility requirements, often with a high conductivity material as shielding materials such as aluminum, copper and copper, silver, etc. can be shielded shell plate, box-shaped, tubular, cylindrical shield. In summary, electrostatic shielding, static magnetic shield, the shield of the shielded high-frequency electromagnetic field theory, physical conditions, shielding effect is different from the materials used have specific conditions, but they are shielded electromagnetic fields, is essentially linked. cell phone jammer has a complete frequency covering range and optional shielding range. 3 Introduction to electromagnetic shielding shielding techniques commonly used in multi-layer shielding and film are generally shielded two. in order to get better shielding effect of shielding layers can be used, its electric and magnetic fields both better protection, especially for the return loss based shield. separated by multiple reflections of the material forming the shell, the thickness of the metal than the same shielding plate can produce better results.
The dealer or customer can master how to install     cell phone jammer at site with the instruction of installation training document. The greater the conductivity, magnetic permeability greater, the smaller the depth of penetration from the energy point of view, the electromagnetic waves in conductive medium when the transmission energy loss, therefore, the amount of the performance of field amplitude attenuation due to a decay factor, high-frequency electromagnetic waves can penetrate thin surface conductor, the conductor surface of the thin layer in the formation of high frequency alternating alternating current (eddy current) This phenomenon is called skin effect., because of the presence of eddy current reflection of electromagnetic waves into space, part of the electromagnetic energy penetration inside the conductor to form a thin layer of the conductor surface electromagnetic waves, and finally put through conduction current part of the energy dissipation of Joule heat.
