A common cell phone signal jammers installed Notes

No damage to the mobile phone the cell phone jammer mobile phone into the mask only when the region makes it impossible to send or receive telecommunications signals, once they left the shield area can be restored to normal mobile phone use. Reliable operation, without someone to maintain SMa-818W-type remote control mobile phone jammer high reliability and long-term stability under all conditions of continuous work. Green environmental protection equipment, human, material type jammers harmless 818W power, and consume less power, and a variety of electronic equipment without any harm. Try to avoid cell phone jammer being sheltered from large obstruction.Fast SMa-818W-type strain shielding device according to the sensitivity of sections of the phone status, usually within a few seconds can make the boot screen of mobile phones within the scope of no signal, to send and receive various types of mobile phone signal shielding effect, shut down after a few seconds , but also make all kinds of mobile phone back to normal use. Choose from a variety of directional antenna SMa-818W-type shielding device according to customer needs can choose a different site directional antenna (factory-configured standard rod antenna to meet the needs of the general situation), can meet a variety of complex field environment, in order to achieve the best possible shielding effect. Keep the cell phone jammer away from strong heat resource.More than the product manufacturers with a single-site adaptability. Our strong R & D capability has its own R & D capabilities, can be customized according to customer needs in various frequency jammers, can also do OEM for our customers OEM products. SMaSMa-818W-type mobile phone signal jammers Use: all kinds of examination room, church, court, library, conference centers, theaters, hospitals, military areas and other use is prohibited place. Venue: to prevent and eliminate the use of modern communication tools cheating candidates. Library: You can maintain a quiet environment for reading and study. Theater: As high-end entertainment, noise can be removed to maintain audience interest in the program. Hospital: when using the phone to prevent the harm caused by the human body and medical equipment failure. Court: the court can maintain the solemn and sacred. Military areas; to prevent leakage of military secrets.Keep the cell phone jammer away from strong electromagnet resource. In short, the phone signal jammers for a wide range, performance, and affordable. A common cell phone signal jammers installed Notes 1.1 The basic shielding installation notes to install a high degree of shielding device preferably not less than 1.8 meters above the ground. From the nearest mobile phone base station is less than 200 meters, shielding effectiveness is inversely proportional with the distance from the base station. That is, the closer the base station away from the shielding radius is smaller. Plug before tightening the antenna, the antenna on the subject of the antenna on the number and host number should correspond to the hole of the subject, do not plug the wrong, but not directly on the antenna does not pick the host power supply. 1.2 jammers standard method for installing the various components of the shielding device components generally include: host, antenna, power adapter. When installing the jammers, as the host and the peripheral antenna within a certain distance (usually 20-30 cm) there is a strong signal to the magnetic field. So that you can guarantee the blocking effect of cell phone jammer. And 220V power cord (strong power) around (usually 5-10 cm) have magnetic interference, therefore, how the various parts of the installation location to be placed on the critical, not positioned correctly, is likely to result in the emission signal interference shielding, impact shielding effect.
