SureCall Flare 3.0 Signal Booster Kit with Yagi Outside Antenna

Overview

The Flare 3.0 Yagi Signal Booster Kit is designed for people dealing with weak cell signal inside their homes, cabins, or small buildings. Whether you're trying to stop dropped calls, improve streaming, or get more reliable data on your phone or hotspot, this system helps bring in a stronger, more usable signal.

At the core of the kit is a high-gain amplifier (72 dB) paired with an outdoor Yagi antenna and a built-in indoor antenna. The directional Yagi antenna goes outside—usually on the roof or an exterior wall—and points toward your nearest cell tower. From there, a 50-foot cable connects it to the base unit indoors, which broadcasts the improved signal to nearby rooms.

This setup works well for spaces with poor indoor coverage but at least a small signal outside. If you can get one bar or better at your chosen outdoor antenna spot, the Flare 3.0 can typically improve service in two to four rooms, depending on layout and signal conditions.

One thing that sets this model apart is the companion mobile app. Using a Bluetooth connection, the app shows live readings for both outdoor signal strength and antenna spacing—two of the most important factors in getting solid performance. You’ll see exactly where to aim the outside antenna and whether your setup has enough distance between components to avoid signal interference or shutdowns.

For homeowners in rural or fringe coverage areas, or for anyone who needs better voice and data reliability indoors, this kit provides a real solution. It works with all major US carriers, doesn’t require a monthly subscription, and gives you control over setup with tools built for everyday users.
