Product Description
300W VSWR Protection AM FM Radio LoJack Prison Cell Phone Jammer
This advanced six-band 300W prison cell phone jammer effectively blocks GSM, CDMA, DCS, PCS, WCDMA, 3G, UMTS, and walkie-talkie communications. Designed to prevent tracking by cell phone signal systems, this equipment is ideal for prisons, schools, churches, conference rooms, hospitals, and any location where unauthorized wireless communications pose security risks or distractions.
RF jammers disrupt radio signals by severing the connection between cellular devices and wireless carriers. With directional or omni-directional antenna options, these systems provide comprehensive signal blocking capabilities for enhanced security and communication control.
Key Features
  • Maximum 300 watts total RF output power
  • Stable performance and cost-effective operation
  • Independent frequency band control via individual switches
  • Power amplifier protection design ensures device reliability
  • Customizable frequency options including AM/FM Radio, LoJack, VHF, UHF, and multiple wireless protocols
