Product Notes: The shielding range of the device will be determined by the local signal strength. In different situation, it will be with different performance. Please try to put the device in a higher position while it is working .Itwill be better. The suggested height is about 8M.  To avoid the loss of function of the device, please try to avoid the device placed on or the metal materials. Do not turn on the power before the antennas is installed, If the antenna is not properly installed in accordance with the manuals, the shielding range will be not so good. Make sure the correct installation before turn on the power. Feature and advantage: Easy outdoor installation and remote controlled operation Any computer with COM port can be available for the program software. It can be controlled in real time including RF output power and separate module as well as all the jammer’s working status.

The mobile phone jammers block all mobile phone signals such as GSM, CDMA, and PHS. And the jammers can also block little smart wireless city phone signal and SCDMA signal. The mobile phone jammers only block downlink frequency from BTS, but do not block uplink frequency from BTS. The jammers has no affection to other BTS, this may be other jammers fail to do. You can rest assured that the jammers do no harm to mobile phones. After getting out the jamming area, mobile phones will automatically reestablish communications and provide full service. The environment protection and rapid reaction is also the features of the jammers.
