Introduction:
SK-01F Remote Control Wireless Phone Jammer is the latest information security product, it can form an electromagnetism protection field around the user, thus prevent mobile phone from receiving and transmitting the mobile signals to the base station; thus it can prevent the secret information leakage through your mobile phone, and also eliminate the noise pollution. The model cell phone jammer for completely stopping all mobile phones operating on the CDMA, GSM, DCS, 3G bandwidth, and it can be adjusted the jamming strength depending on different demands. The cell phone jammers are now a necessity for law enforcement and the military to interrupt communications by criminals and terrorists, and also for accomplishing a more cultured society.

Features of the SK-01F Remote Control Wireless Phone Jammers:
ò Taking use of technology of interference super high frequency.
ò Intelligence controlling technology taking charge of the power outputting within the scope of 3 meters.
ò Effectively making subsections, just interference downlink and causing no interception of base station.
ò The Antenna can swivel type 360 degree rotary adjustment and 90 degree adjustment
ò Battery or Mains compatible.
ò To keep you away from noise or disturbance of unexpected cellular phone calls or text messages (SMS)
ò World wide compatible.
ò To block cellular phone communication links within an effective area.
ò No transmissions or receptions of cellular phone calls in coverage area.
ò All specified frequency bands will be blocked simultaneously.
ò For using at meeting rooms, conference rooms, museums, galleries, theatres, concert halls, churches, temples, restaurants, classrooms, training centers, factories, banks, trains, buses etc.
ò Can be adjusted depending on different demands.
Important Notice:

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