Cellular Jammer 12V, 24V, 36V– Car Charger Cellular Jammer

Model: SK-5 Cellular Jammer – Car Charger Cellular Jammer

Introduction:

SK-5 cellular jammer is the new released information security product of cellular jammer.

The advanced feature of the new cellular jammer is can be power supported by car charger (12V-24V). The principle of cellular jammer is sending the disturbance signal that is the same frequency to the downlink to the cell phone base station. Cellular jammer blocks the logical signal channel like GSM, CDMA, 3G, PHS, DCS, GPS, Wireless Video, etc.

In the efficient jamming area the cellular phones can not be dialed, which display “Not in service zoon.” In coming calls are blocked as if the cellular phones were off. Signal Knight is a professional cellular jammer manufacturer; we can design and develop different bandwidths frequency cellular jammers for different country clients’ demands. The SK-5 cellular jammer is now a necessity for law enforcement, privacy protection and the military to interrupt communications by criminals and terrorists.

Features of the SK-5 Cellular Jammer:

• Car charger power supply (12V-24V)and normal power supply (110-240V).
• Effectively making subsections, just interfering downlink and causing no interception of base station.
• The antenna can swivel type 360 degree rotary adjustment and 90 degree adjustment
• To keep you away from noise or disturbance of unexpected cellular phone calls or text messages (SMS)
• To block cellular phone communication links within an effective area.
• Using at meeting rooms, conference rooms, museums, temples, mosques, galleries, theatres, concert halls, churches, restaurants, classrooms, training centers, factories, banks, trains, buses etc.  

Specification: 

 *The mentioned jamming distances are based on the base station signal strength; actual jamming distance will be varied depending on the strength and type of cellular system.  

How to Install:

1.     Install this device at the height about 1.5-1.7m will get the best jamming result, keep all the antennas in vertical.

2.     Never install this device close to the wall; the wall will affect the interference signals. Put this device 30-50cm away from the wall.

3.     One set of this device can block all types of cellular system including analog (AMPS, TACS, NMT) and digital (GSM, DCS, PDC, TDMA, PHS, PCS, iDEN, CDMA, WCDMA) signals up to 60m radius, covers an individual room of around 2800 square meters.

4.     To cover an area bigger than 10000 square meters, please install multiples of this device to ensure better jamming effect, e.g. in an individual space of 15000 square meters, you should need to install 2 or more devices working together.

5.     This device is not able to cover different spaces divided with walls. Install individual jammers in different partition of a building to ensure the best jamming effect.

How to operate the SK-5 Cellular Jammer with Car Charger:

1.     Install the antennas fully correctly in vertical firstly.

2.     Plug the power adaptor into the electricity outlet (110V-240V)

3.     Before turn on the power switch, always check if the antennas are installed securely. If you turn on the power switch without the antennas installed on this device, it shall heavily damage this device. Never remove the antennas when the device is working; otherwise you will void the warranty.

 Notice of Use SK-5 Cellular Jammer – Car Charger Cellular Jammer:

Be sure to connect all the antennas firstly before the power supply is switch on. Please do not take off antennas when the machine is working. Otherwise, it should cause heavy damage to the device and cause the device out of work. It will also void warranty.

Antennas shall be used vertical to the ground, working more efficiently.

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.

Use several units in the same place will get bigger coverage area.

For better performance indoors, use this device in an individual space. The device is not able to cover different spaces divided with walls. Install individual jammer in different partition of a building to ensure the best jamming result.

The jamming area is influenced by the location of the cell tower and the obstacles between cell tower & the cell phone jammer. It means that in normal condition if the distance is close between the cell tower & the cell phone jammer, it will have very less jamming area. Likewise, if there are obstacles & walls between the cell tower & the cell phone, the cell phone jammer will give less jamming area.

Usually, at the same place, you will get longer jamming distance indoor, because the wall and floor will reduce the base station signal strength.

Any ruin and disrepair caused by incorrect operation and disassembly will exclude from the repair with free of charge.

1.     Unauthorized repair or dismantle of this device will void all the warranties.

2.     Antennas shall be used vertical to the ground, working more efficiently.

3.     Please do not take off antennas when the machine is working. Otherwise, it should cause heavy damage to the device and cause the device out of work. It will also void warranty.

4.     Install the antennas before switch on the device, otherwise will heavy damage the jammer.

5.     Persons with Pacemaker implants are prohibited from using this device.

6.     Avoid water; over-wet, over-hot, high-voltage and high magnetism.

7.     Do not store this device in an excessively hot place.

8.     Avoid knocks or dropping this device.

FAQs (Frequently Asked Questions):

Will Cellular Jammer interfere with the other electronic equipment to work in normal condition?

No. Because the electromagnetic signal sent by Cellular Jammers are totally used in the band that regulated by government and just have interception effect to cell phone communication.

Is Cellular Jammer harmful to the human body and cell phone?

Please do not need to worry about it. The intensity of electromagnetic signal sent by Cellular Jammer is in compliance with the national standard of environmental electromagnetic wave health. The signal sent by Cellular Jammer is relatively small and no harmful to human body according to the testing result. Meanwhile, this device just damages the receiving condition to the cell phone and makes the normal connection between cell phone and base station impossible. Therefore, no damage will occur on cell phone itself.

Is there any difference of distance between using Cellular Jammer indoor and outdoor?

Yes. Generally speaking, outdoor signal is bigger than the indoor signal. Thereby, the shielding effect is worse in outdoor. Strictly speaking, whether using indoor or outdoor, the effective distance of interference is related to the surrounding around, for example the distance between different base stations, positions of installation etc.

Is the Cellular Jammer has the same effect to GSM cell phone and CDMA GPS + Cell Phone?

The capacity of anti-interference of CDMA is much better than GSM Cell phone. So the interference effect for GSM GPS + Cell phone is better than CDMA Cell phone.

The shell of Cellular Jammer will become hot after working for some times. Does the long working time will damage the machine itself?

It is very normal. When designing, we are thinking of taking use of the conductivity of metal shell to help the heat sinking during our designation. By this way, the machine can be kept in good working condition for long time.
