Mobile Phone Jammer Introduction:
Now let us introduce this mobile signal jammer to you ,and make you better understand about the positions of all the buttons, function of accessories and other hardware.
Knowing the working principal of the UHF/VHF Jammers? The working principal of the UHF/VHF Jammer is similar to the mobile phone jammer, as it works to prevent the UHF and VHF frequency from receiving and sending signals and soon lose the normal working use. And here you can know more about the UHF/VHF signals and the UHF/VHF jammers.
UHF and VHF are low frequency bands and of which the frequency bands are VHF 130-180MHz and UHF 400-450MHz and such kind of frequency bands are also widely used in many aspects in the society like at the traffic lights, lamp-posts, mounted on the walls and under the sun breakers, and so many other places and situations. And if wanting to block these two frequency bands and the using of the walky-Talkie, the UHF/VHF Jammers can help to reach the this special usage.

Mobile Phone Jammer Technique characteristics
   1. Taking use of super-high frequency with high effective power amplifier.
   2. Effective output power (channel power) to ensure big interfere radius.

   3. Only interfere downlink frequency of mobile system,without disturb normally working of Base Stations.
   4. Imported elements: Slow start up design of circuit. These elements can maintain the stable operation condition with high integration.
   1. Three N interfaces, Which are using to connect antenna
   2. One power supply interface for AC220V input
System fittings
    Jammer machine,power line,RF cables and antennas etc. The 3 channels are responsible respectively for 3 different frequencies.
Omni Antennas
Frequency:130~180MHz, 400-450MHz, 450-500MHz
Gain: 7dBi
Interface: N
RF Cables
3 pcs 5-meter 1/2 super soft cable.
    1. Be sure to connect all the antenna before the power supply is switch on. Please do not take off antenna when the machine is working.
    2. Antenna shall be used vertical to the ground, working more efficiently.
    3. Please don’t put the jammer in the water and fire to avoid using in the bad

condition of over-wet, over-hot, high voltage and high magnetism.
    4. If the jammer can not be charged or other unconventionality( the indicator light doesn’t light up), please contact with the distributor in local place. Any refit and incorrect repair is not allowed.
    5. Any ruin and disrepair caused by incorrect operation and disassembly will be excluded from the repair with free of charge.
