Cellular Communication Guard CK-280/15E


  
The CK-280/15W series is based on an advanced RISC Micro–Controller together with a PLL synthesized transmitter, in order to ensure minimal interference outside the desired band, high processing quality, and reliability.
 
   The CK-280/15W series of Cellular Jammers has been designed to work with unstable power voltages in range of 90 – 264 V.A.C. or to be fed from an external 24V battery for backup. (As an option, the CK-280/15W can also be fed from a standard 12V battery).

   The CK-280/15W series has an output power of 320mW – 10W (25dBm – 40dBm) per each cellular band, which can be sets using 4bit switch, in steps of 1dB, for optimal tuning of the coverage range.

   Use of high performance cellular [OMNI] antennas or directional antennas with a front beam (of 65º, 90º or 180°) and back reflector enables more exact coverage control, and prevents almost completely the back reflection and results in a level of less than 0.1% (front to back ratio > 30dB) for maximal human protection.
