Q: What is the purpose of the outdoor antenna included with the SureCall Flare 3.0?

A: The outdoor antenna helps extend voice and data coverage in buildings and rural environments.

Q: What is the maximum coverage area of this cell phone signal booster?

A: The maximum coverage area is 3003.1 square feet.

Q: How does the SureCall Flare 3.0 booster help extend phone battery life?

A: By boosting the signal strength, your phone doesn't have to work as hard to find a signal, which can help extend battery life.

Q: Does this signal booster work with all cell phone carriers?

A: Yes, this signal booster supports all U.S. cell service carriers.

Q: What is the maximum frequency supported by the SureCall Flare 3.0?

A: The maximum frequency is 2155 megahertz.

Q: What is the maximum gain provided by this signal booster?

A: This booster provides a maximum gain of 72 decibels.

Q: if this is installed in the house, will it reach out into the driveway or yard as long as it is within a 3,000 square foot range? Or can I expect this boost to stop at the walls?

A: Dear Deadspot, The SureCall Flare 3.0 is designed to amplify RF Sheltered areas... basements or upper level of the house (particularly if you have a metal roof or other radio unfriendly building materials). So the official answer to your question is: Flare 3.0 is designed to amplify cellular signal 'inside of your house'. The inside coverage estimate of 3.000 sqft is the maximum and it assumes that signal power on the roof is moderate or even good. Since you are asking if Flare 3.0 will also amplify the outside signal... that suggests the cellular signal power on the roof is NOT very good. When outside signal is weak the Flare 3.0 inside coverage will be smaller. Dear Deadspot, can you make a cellular call from the roof of your house? If not, can you at least text from the roof of your home? If you have ZERO outside coverage there will be nothing for Flare to boost.
