SureCall FlareDB+ Signal Booster Details

The SureCall FlareDB+ increases voice, text, and 4G LTE data for Verizon, AT&T, and T-Mobile operating on bands 12/13. It greatly enhances 4G and LTE cell service for all your wireless devices (smartphones, notebooks, hotspots, etc.). Furthermore, it works regardless of phone model (iPhone, Android, Samsung Galaxy, etc) or phone type (4G, 5G, etc.)

This cell signal booster features an outdoor yagi antenna and a sleek, aesthetically pleasing booster. It’s one of our easiest signal boosters to install and can cover up to 3,500 sq ft under optimal conditions thanks to SureCall’s patented 2XP technology that doubles the reach to and from the cell tower. The cellular repeater itself offers up to +72 dB gain.

Installing the Flare is extremely simple:

  1. Install Outside Antenna.
  2. Connect to the Amplifier.
  3. Place Flare Booster
  4. Power On

The most “difficult” part is installing the Outside Antenna.

You’ll need some general handyman skills but nothing too specialized. If you prefer having someone else do the job, you can also contact your local general contractor, electrician, or anyone who’s installed a satellite TV dish.

Let’s start:

  1. Find The Best Outside Signal: Begin by finding the best signal outside your house. This is done by walking around the perimeter of your home and either using the number of bars on your phone (ok method), smartphone apps (good method), or Field Test Mode (great method) to find the best location. Pro tip: Locating the side of your home getting the best signal is the MOST CRUCIAL step of the installation process.
  2. Install Outside Antenna: The area with the best signal is where you will mount the yagi antenna. Place the antenna as high up as possible, ideally on the roof, although the fascia or gable is acceptable. Then point it toward your nearest cell tower.
  3. Place Flare: The inside antenna is built into the Flare, so place it wherever you need signal the most.
  4. Power on: Plug in the power supply to the Amplifier and to the wall outlet. The amplifier will sync up and if you see all green lights, then green means GO! Check to see near the inside antenna how much better signal you’re getting. Pro tip: Any post-installation adjustments will require rebooting the amplifier. Simply unplug the power supply for 5-10 seconds and replug to reboot the system.
