The object of low heat resistance should keep away from cell phone jammer

The object of low heat resistance should keep away from  cell phone jammer  
The components will have to implement the static magnetic flux leakage magnetic shielding, to improve the quality of equipment or product using electromagnetic shielding, suppression interference, electromagnetic shielding, interference suppression. If the installation height of  cell phone jammer  is 1.5-2m, the shielding range will be the biggest. And enhance equipment reliability and improve product quality electric, magnetic, electromagnetic shielding is different! magnetic field shielding, is both a practical sense but also has theoretical significance of the problem, according to the conditions different electromagnetic shielding can be divided into electrostatic shielding, static magnetic shielding and electromagnetic shielding three cases, three cases with both a qualitative difference, but also intrinsically linked, not be confused. If switching on the power supply without installing the antenna,  cell phone jammer  might be damaged. Electrostatic shield in the static equilibrium state, regardless of is hollow or solid conductor conductor; regardless of how many live conductor itself, or the conductor is in the external electric field, there must be potential for the other body, the internal field is zero, which is the theoretical basis of electrostatic shielding, because the electric field has a closed conductor shell typical significance and practical significance, we closed conductor shell of the electric field, for example for some discussion of electrostatic shielding. For the emission power of  cell phone jammer has been adjusted before delivery, the customer doesn’t need to adjust after purchasing. A. closed conductor shell internal electric field from the charge or the electric field outside the shell closed conductor shell internal electric field from the charge or the electric field outside the shell impact the internal electric field is not closed conductor shell charge or electric field outside the shell as the shell without the shell live outside the body and charge q, so that the shell wall is charged electrostatic induction electrostatic equilibrium shell without the electric field, which is not to say the charge is not in outer shell shell electric field, the root farm.  ② practical applications do not strictly completely enclosed metal shell, with a metal mesh instead of metal shell can achieve a similar electrostatic shielding effect, although this is not completely shielded and thorough. ③ in static equilibrium, the ground wire is no charge flow, but if the shell is shielded charge over time, or live near the outer body shell charge change over time, will make the ground in current shield is also possible residual charge, which shielding effect when the turn is not complete and not complete.If the base station signal is too strong to be inhibited, 1 or 3 large-type directional  cell phone jammer  should be added.
