Interphone High Power Mobile Phone Jammer 300W VHF 130-180MHz / UHF
400-450MHz
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.
Interface
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.
Antenna
Omni Antennas
Frequency:130~180MHz, 400-450MHz, 450-500MHz
Gain: 7dBi
Interface: N
RF Cables
3 pcs 5-meter 1/2 super soft cable.
Notices
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.
