The antenna direction of cell phone jammer

Electromagnetic gasket sealing gasket installation method to use electromagnetic positive compression and sliding compression two. varnish sealed as far as the environment tank installation: the role of tank liner and fixed limit excessive compression. a tank installed as far as possible: a high shielding effectiveness. groove shape and size: the shape and size of tank: the shape of a straight installation of slot slot and two dovetail slots species, straight groove simple, but easy to fall out of the liner. dovetail groove is not the problem. width to ensure there is enough space to allow gasket is compressed when the stretch.The shielding radius of cell phone jammer is also independent on distance away from the base station, buildings around and so on. liner fixed: Fixed liner: conductive adhesive then, but it has two drawbacks: one is to increase the cost, the other is the conductive adhesive will happen down the shielding effectiveness caused by aging. with non-conductive adhesive, fastening screws in place through a small drop so, stick Although the non-conductive plastic place, but played a conductive contact with the metal screws role and shielding effectiveness is relatively stable. to prevent electrochemical corrosion method: to prevent electrochemical corrosion method: one side in contact with the external environment, sealed with non-conductive material, to prevent the electrolyte into contact with conductive pad with a combination of the shield surface. sliding contact: sliding contact: Reed allowed only finger sliding contact. Install reed, the reed to pay attention to the direction, so that by the compression force, the freedom to stretch.The needed shielding range of cell phone jammercan be met by selecting the appropriate installation position and height. In general, the reed can glue back then, but pay attention to curing time (see reed manufacturer's instructions). more harsh environments (temperature too high or too low, the mechanical force is too large, etc.), available card loaded structure the position of the screw: screw position: Under normal circumstances, screws installed in the liner inside or outside is not very important, but demanding applications in shielding, screw the outside of the liner to be installed, to prevent the screws penetrate the shielding box, causing additional leaks. fastening screw spacing: fastening screw spacing: spacing should be appropriate to cover the liner to prevent the elastic deformation under the effect, resulting in a greater gap. flanges as thick, to prevent deformation.

Completely shielded electric guitar electric guitar a thorough transformation of the shielding, interference noise can be reduced to a minimum, greatly improved signal to noise ratio.The antenna direction of cell phone jammercan be adjusted to get the needed shielding range of cell phone jammer. It is noteworthy that the methods described in this article applies not only to hand piano maker, guitar on most of the finished product is also effective. If you disassemble different grades had different brands of guitar, will find that although the screen is very simple in principle, but each vendor's approach and emphasis there is a huge difference. Shielding only the most basic access to most of the original ground network, requiring higher can paste in the inner cover foil. Most brands only in its high-end models use a cavity wall shielding paint tank, metal shield cover and other more stringent program. Basic skills required for welding circuit unless you very confident, and on the guitar have a basic understanding of the circuit, it is best to find professionals or mentioned in this article the operation.If the needed shielding range is very big, it can be realized by installing several cell phone jammer.
