Two ways to improve interference shielding effect

　　After the mobile phone jammer is turned on, the coverage of the shielding signal it sends generally ranges from tens of square meters to hundreds of square meters, while some high-power mobile phone jammers can cover thousands of square meters, or hundreds of meters in radius, and the mobile phone signal will Hidden.

　　Due to various reasons, it is hoped that the mobile phone jammer purchased and used can expand the coverage of the shielded signal, or some methods can be found to greatly improve the shielding effect of the mobile phone jammer.

　　It is generally improved in two ways. The first aspect is to analyze the installation environment and surrounding environment of the mobile phone jammer. Are cell phone jammers mounted on the wall or table top? Is the installation height too high? The usual recommended height is 2-3 meters.

　　Or is it too low to put directly on the ground? This will cause too many obstacles in the signal transmission path, serious signal attenuation, and affect the shielding effect. In addition to these factors, also observe and analyze the distribution of surrounding base stations. The installation location of the cell phone jammer gps is recommended on the transmission path from the base station to the site, usually near the window of the room.

　　The second aspect is to analyze from the mobile phone jammer itself. Whether the mobile phone jammer is a qualified product of a regular manufacturer, whether its working frequency band is completely correct, and whether it has a frequency bandwidth. Average output power reduced? Is the frequency band division of mobile phone jammers reasonable? Are there overcombined frequency bands? Does the antenna gain value match the phone shield?
