  • Mobile phone detection -03 simultaneously detects four band (GSM/ DCS/CDMA/3G) transmission signals.
  • Each band is designed with individual detection circuit for high sensitivity and consistency.
  • Broad band Log Amplifier design.
  • Active striping filter designed for high selectivity and low false alarm.
  • It can look through the mobile phone signal and can automatically activate the jamming device to break the communication when needed. Therefore, it can eliminate the health concern of always-on jamming radio wave to human body.
