The mobile phone can be fully restored to normal use after leaving the GSM signal shielding area


  The mobile phone can be fully restored to normal use after leaving the shielding area. The working frequency bands are CDMA800, GSM900, DCS1800 and PCS1900. After receiving the portable battery jammer (desktop jammer without battery), it needs to be fully charged within 6-10 hours; All antennas must be installed as marked (1-1 2-2 3-3 4-4 5-5 6-6 7-7 8-8 or GS M to GSM GPS to GPS).

  That is to say, the signal is always in a relatively static state, does not interfere with other electrical equipment, and is harmless to human body. The electrical signal sent by gsm jammer is undoubtedly an electromagnetic signal, but the jammer will never have any device to communicate with it, so a sudden change signal can never be formed. Operating frequency: 869-94MHz, 825-960MHz, 1805-1880MHz, 1900-1990MHz, etc. This scanning speed may cause interference to the SMS signal received by the disorderly code mobile phone, so the mobile phone cannot detect the normal microwave signal data sent by the base station. If it is close to the signal base station, the jammer is very invalid!

  At present, the main products include UAV countermeasure jammer, mobile phone signal jammer, GPS jammer, signal jammer and other products. More importantly, do not open the shield without an antenna! Interference range: field signal strength<=- 75dBm. Disturbance distance varies depending on signal strength and location.
