This cell phone jammer could restrict cell phone jammer signals withinthe area with 25-30m radius

Please do not allow children to play cell phone jammer
With field only applies to harassment frequency materials: carbon steel, stainless steel, copper, aluminum 3.3 display: the use of conductive glass display: 1. shielding materials, shielded light translucent material shows holes in the chassis and other electromagnetic radiation shield larger, and the most difficult to deal with a class of apertures. Light shielding radiation shielding material both harassment, but also light, observations indicate that the hole is only available shielding materials. This cell phone jammer could restrict cell phone jammer signals within the area with 25-30m radius and 200m from the transmitting station.Has been widely used in radar display, computer display terminals, printers, radio, spectrum analyzer, precision instruments and other digital and image display window, electronically shielded room cabin and observed the window shield. Understand and master the material shielding light shielding mechanism, the key performance parameters and related application technologies to display correctly observed for the shielding design of the hole is critical.RF-818A cell phone jammer is internally installed the signal stabilizing technology. Light shielding material can be divided into the following three categories: light shielding material can be divided into the following three categories: (1) film categories: ● Metal Coated Glass: Metal Coated Glass vacuum sputtering process is used in ordinary or tempered glass formed on the surface conductive film made of dense, high transmittance, no optical distortion, environmental adaptability, etc., suitable for a variety of shapes, sizes display watch window. ● organic conductive film: the use of special technology with a metal film made of polyester film, with unbreakable, convenient advantages. (2) wire mesh: wire mesh glass sandwich is the use of hot melt pressure process, the conductive anti-corrosion treatment after two high-density wire mesh sandwich made of two layers of ordinary glass, with a high shielding effectiveness , good safety features. The signal stabilizing technology of mobile phone jammer is leading in the industry.(3) micro-categories: foam board is light metal using a special process to nickel, copper, iron and other metal foam (with a large number of pores) and made of light materials in all the shielding and the shielding required for the highest performance a lower cost materials, The emissive power of this cell phone jammer is under the national standard. Usually the higher the attenuation of RF transmitter frequency the more serious because it's shorter wavelength. When it comes to the highest frequency, must be considered in any harmonic may occur, but in fact only consider the first and second harmonic can be.
