HTCX-100A is the small-type directional cell phone jammer
It is ideal for a plane wave normally incident to the infinite thin shielding plate, but can also be used for non-plane-wave radiation similar to the limited size of the irregular shape of the shield plate and thin shell case (error less than 3dB). Theoretical estimates of housing using transmission shielding effectiveness SE, in the high frequency (greater than 10MHz), the absorption loss dominant, so for most shielding applications, thick enough to shield any material can be provided to meet the practical shielding effectiveness. HTCX-100A is the small-type directional mobile phone jammer.This is from a selection point of view, and as a screen shielding shell structure effect also depends on many factors, such as whether there are gaps, into the outlet pipe of the treatment. References in the high frequency (greater than 10MHz), the absorption loss dominant, so for most shielding applications, thick enough to shield any material can be provided to meet the practical shielding effectiveness. This is from a selection point of view, and as a screen shielding shell structure effect also depends on many factors, such as whether there are gaps, into the outlet tube processing [discussion] conductive and conductive foam pad how to design in order to achieve the most good electromagnetic shielding effect? 2009-05-21 16:54 most of the conductive pad / foam has sufficient shielding to enable equipment to meet EMC standards, the key is properly within the shield design of the gasket. HTCX-100B is large-type directional cell phone jammer.Gasket system: a key factor to consider is compressed, the compression gasket in between the liner and high conductivity. Gasket between the liner and the poor will reduce the conductive shielding efficiency, the other joints occur if the less a slit-shaped groove formed by the antenna, the radiation wavelength smaller than the gap length of about 4 times. Ensure continuity gasket surface first to ensure a smooth, clean, and after the necessary treatment in order to have good electrical conductivity, these surfaces must be covered before the engagement; other cushioning material such shielding gasket adhesion with continued good also very important. Compressibility characteristics of conductive pads can make up any irregularities in the gasket. CONSDATA-1000A is warfield-type directional cell phone jammer.All pads have a minimum contact resistance and effective work, designers can increase the compression strength of the cushioning pads to reduce the number of the contact resistance, of course, this will increase the sealing strength, the shield will become more curved. Most of the original thickness of the liner in the compressed 30% to 70% better results.
