FlexPro 3G With Yagi

This booster system boosts 3G cell phone signal inside buildings for up to 5,000 Sq ft. The wide band Yagi antenna works great where the cell phone reception is spotty and using its multiple dipole design, the yagi antenna captures the weakest of signal and the 72dB gain amplifier makes it multiple times stronger for increased reception.

Key Features

  • Completely eliminates dead zones and dropped call problems
  • Requires no set-up of any kind, just plug the device to the power supply and watch your bars rise
  • This amplifier is compatible with all network technologies: CDMA, TDMA, GSM, AMPS, in addition to 1x and 3x data protocols such as HSDPA, EVDO and EDGE
  • 3 Watts max output uses the full potential of your cell phone’s power
  • Boosts the cell phone signal for both incoming and outgoing calls. That is to and from the cell towers
  • Oscillation indicator to indicate if there is any feedback detected between the external antenna and the base unit
  • Automatic gain control ensures stable operation
  • No Internet connection or contract required
  • Easy install involves no set-up or software
  • FCC approved amplifiers and antennas require no set-up or software installation. Just power up and see your signal rise
