SureCall FlareDB+ for Verizon, AT&T, T-Mobile - Yagi Antenna

In Stock

Item Number: 10546
Model: SC-FlareDB



The SureCall FlareDB+ is the most powerful cell phone signal booster in its class, designed to improve voice and 4G LTE data signals for Verizon, AT&T, and T-Mobile devices operating on Band 12/13, including hotspots and MiFi devices. It comes equipped with SureCall’s exclusive 2XP technology that doubles uplink transmission power when compared to the closest competitor to keep all devices connected in the weakest of signal environments, even in the most remote locations. FlareDB+ also features a patented indoor booster design that gives it a simplified setup for easy and reliable cellular coverage in 2-4 rooms of a home or small building.

FlareDB+ comes kitted with our powerful outdoor Yagi antenna and our patented signal booster, which is an amplifier and indoor antenna combined in an attractive housing that is designed to be placed on an open tabletop or bookshelf to streamline the system's design for easier install and a smaller footprint.

Amplifier Features:

  • Coverage area*: up to 3000 square feet
  • All-in-One Kit? YES
  • Compatibility: Verizon, T-Mobile, and AT&T LTE bands 12 and 13 only. Please confirm which bands your device is using prior to purchasing:
    • iPhone: Dial *3001#12345#* and press Call Click 'Serving Cell Info'
      Then 'Freq Band Indicator' and check band number
    • Android: Download and install the 'LTE Discovery' App Click ‘Signals’ and check the band number

Installation notes:

  • In order for your system to function properly, you must maintain adequate separation between the outside and inside antennas (if the antennas are too close together, there will be oscillation/feedback between the antennas and the amplifier will shut down). This amplifier requires approximately 30' of separation between the outside antenna and the amplifier's built-in antenna. Separation can be horizontal or vertical.
  • The Yagi antenna must be aimed directly at the cell tower - if it is not aimed properly or if there are too many obstructions between it and the cell tower, it will not be effective.

Features & Benefits:
