Product Description

The SureCall FlareDB+ is a multicarrier signal booster system designed to boost voice and data signals even in remote, low-signal locations.

The FlareDB+ boosts voice and 4G LTE data signals for Verizon, AT&T, and T-Mobile devices that operate on Band 12/13. This includes hotspots and MiFi devices. It is 4G & 5G phone compatible. The Flare DB+ will boost voice and 4G LTE data signals on Verizon, AT&T and T-Mobile 5G phones and devices.

The FlareDB+ will cover any home, cabin or small building in 2-4 rooms, up to 3,500 sq ft. It is ideal for remote locations, far from cell towers. SureCall’s exclusive 2XP technology doubles uplink transmission power, delivering twice the signal power to the tower to keep devices connected and stop dropped calls.

The powerful outside yagi antenna is perfect for weak signal environments. Indoors, the signal booster unit and omni-directional server antenna are combined in one housing. This one-piece base unit is designed to be placed on an open tabletop or shelf for easier installation and a low-profile appearance.

How it works

1 - Outdoor antenna

The outdoor antenna receives and transmits signal to nearby cellphone towers. Outdoor antennas can be either directional or omni-directional.

2 - Cellular amplifier

The amplifier (or "repeater") boosts the signal coming to and from and going to the cell phone tower. The "gain" of the amplifier describes how strong the amplification is - you'll see that word scattered across our product pages.

3 - Indoor antenna

The indoor antenna rebroadcasts the signal inside the building. Some kits have more than one indoor antenna to help distribute the signal.
