New Coming 3G 4G & WiFi Blocker with Omnidirectional Antennas

Yesterday we have introduced a new coming hidden white cell phone and WIFI blocker,here is another 2G 3G 4G cell phone blocker,same in functions,for cell phones and WiFi signals ,too.

The differences of the two are shape design, jamming range,antennas.

The first difference ,shape designing.What the more are connectors for 8 antennas,the last hidden signal jammer was designed as built-in,so it is higher in size than the one.Related to this is property of antennas,although all of them are for same radio frequencies :CDMA 851-894MHz,GSM 925-960MHz,DCS 1805-1880MHz,PCS 1920-1990MHz,3G 2110-2170MHz,4G1 2300-2400MHz or 2550-2690MHz,4G2 725-770MHz or 790-826MHz and WiFi 2400-2500MHz.Antennas’ design is different with others who have also,from the length,appearance.The 3G 4G cell phone and wifi blocker is a omnidirectional antennas blocker,the previous one has directional antennas.The most difference of the two is ,we have to put the previous one towards to the direction where the cell phone signals from.But the Omnidirectional antennas blocker dosen’t have to do this,it emits jamming signals in 360 degree around it.When ell phones and wifi signals come from all directions,we need a Ominidirectional antennas blocker rather than a direction antenna and won’t worry the missing.

Maximum jamming range of the Ominidirection antennas blocker is 50 meters ,10 meters than the other one,what supports this is a more powerful output 40W.

Anyway,it is not very meaningful to compare two different signal jammers,every of them were invented for diverse situations ,customers,problems.You may choose one according to your practical problem,for example,if you are around with boring cell phone & wifi signals,you need the Omnidirectional antennas blocker.
