The SureCall FlareDB+ Signal Booster kit is an affordable alternative to the Flare 3.0 signal booster. It only boosts bands 12 and 13, which are the frequencies used by AT&T, Verizon & T-Mobile for their 700 MHz networks. These are typically the only networks found in rural locations, so this solution is best for boosting signal in rural homes and businesses.

If you do not live in a rural area or want to boost all of the frequency bands that are used by the major carriers for maximum signal quality and data speeds, then we recommend the Flare 3.0 instead of the FlareDB+.

The FlareDB+ features a sleek, aesthetically pleasing inside unit and a powerful outside directional antenna to receive the existing cell signal.

Why the SureCall FlareDB+?

  • Affordable alternative to a 5-band booster.
  • Works wirelessly. No physical connection to your phone required.
  • Supports multiple phones and AT&T, Verizon & T-Mobile at the same time.
  • Everything you need is included in the kit.
  • Fewer dropped calls
  • Faster Internet data speeds
  • Better voice quality
  • Texts that send quickly
  • Longer battery life

Your purchase is covered by our 60-day money-back guarantee, so you can try it risk-free, and our friendly, US-based technical support team is standing by to assist with anything you need. Your equipment is also covered by a 3-year manufacturer warranty, for extra peace of mind.

Recommended For

The SureCall FlareDB+ is an ideal solution for boosting signal in a rural small home, small office, mobile home, cabin, cottage, or other small to midsize space.

How it Works

How the SureCall FlareDB+ works

The SureCall FlareDB+ signal booster system uses a powerful, yagi directional outside antenna that's mounted on a pole at or above the roofline of your home or office where it can pick up the strongest existing cell signal in your area. That existing signal is received by the yagi antenna and sent over a cable to the SureCall FlareDB+ inside unit, which boosts the signal and broadcasts it in all directions to the mobile devices in the area. The inside unit should be located in the center of the space that needs boosted signal in order to be most effective.

The entire process also works in reverse, so you get a strong and reliable connection back to your carrier.

Estimated Inside Coverage

The strength of your existing outside signal, measured in the location where you plan to mount the outside antenna, has a direct impact on the amount of inside coverage you'll get from a signal booster. The table below shows how much coverage you may get depending on your outside signal strength:

Existing Outside Signal Strength Estimated Inside Coverage
Strong (5 Bars) Up to 3,000 sq ft
Medium (3-4 Bars) Up to 2,000 sq ft
Weak (1-2 Bars) Up to 500 sq ft
None (0 Bars) No Coverage

Please Note: It is important to remember that there are many factors that impact the size of the inside coverage area, so actual results may vary from these estimates.

Additional Coverage

If you need more coverage than the SureCall FlareDB+ with Yagi Antenna will provide due to a weak outside signal, then the SureCall Fusion4Home with a Yagi Outside Antenna and Panel Inside may be a better choice for you. It has a more powerful inside antenna to provide more inside coverage with the same strength outdoor signal. Please contact us if you have any questions or would like more information about either of these systems.
