Expected Inside Coverage.*

  • 500 square feet with 1-2 bars signal.
  • 2,000 square feet with 3-4 bars signal.
  • 3,000 square feet with 5 bars signal.

The SureCall Flare with its directional Yagi Antenna is ideally suitable to boost signals in your home office, mobile home, basement, cottage, cabin, small office, small home, or anywhere with a weak to medium outside signal, and having a small to medium sized space to cover.


SureCall Flare signal booster system uses a powerful, directional yagi outside antenna to pick up the strongest cell signal available in your area. That signal is then transmitted to the Flare unit inside via a cable, where it is boosted and broadcast in all directions. Inside unit should be located in the center of the space that needs boosted signal in order to be most effective.

Entire process also works in reverse, so you get a strong and reliable connection back to your service provider.

Additional Coverage.

If your outside signal is weak and you need more coverage than what this combo can provide, the Fusion4Home with an outside yagi antenna and inside panel antenna may be a better solution. Due to its powerful inside antenna, it is able to provide more inside coverage with an outdoor signal of the same strength.

Installation Overview.

Installation of the SureCall Flare Signal Booster Kit and Yagi Antenna is easy with our cell phone signal booster quick install guide. However, you will need to run cable from exterior Yagi/ Log Periodic antenna into the building and possibly drill and screw in components. If you are capable of doing this level of installation that is great. Otherwise, you may want to hire us for installation or even any electrician, general contractor, handyman or satellite TV installer to do the job.

Before you start, you might want to do a soft installation, where none of the components are permanently mounted, to make sure that the system performs the way you want. Once you're happy with the results, continue to install everything permanently. Also read the full installation instructions here and in the manual provided before you start.

  1. The first step is to determine where on the roof you receive the best signal. Once you know that, mount the yagi antenna on a pole (pole not included) as high above the roof as you can. Run the RG6 cable from the antenna into the house, using a vent or soffit if possible, although you may have to drill a hole if there is no convenient other route.
  2. Inside unit should be located in the middle of the space that needs to be covered. To start, run the cable to the center of the part of the house that needs the best signal. Connect the cable to the antenna port on the unit and connect the power adapter.
  3. With the components connected, power on the amplifier by plugging it in. The lights should flash while the unit is powering up. Once it has powered on, the power LED and one or both the alert LEDs should be on. You can ignore the alert LEDs if they are yellow as this indicates the amplifier is working properly. If the LEDs are red however, there is an issue that needs to be resolved. Increase distance between outside antenna and the 2-in-1 booster and inside antenna unit.
  4. The directional antenna must be aimed to achieve the best results. When the antenna is aimed and mounted, ensure that it is parallel to the ground - don't aim it down at the ground or up at the sky. Start by pointing the antenna in one direction. Turn the system on and have someone inside stand 10 feet in front of the inside antenna and use their phone in field test mode to take a signal reading. Turn the outside antenna 45 degrees (1/8th of the way around) and then wait for 60 seconds. After the 60 second, let the person inside take another signal reading from the same spot. Repeat the process until you have gone all the way around, and then mount the antenna facing in the direction with the decibel signal reading closest to 0 (strongest signal). If possible, mount the antenna on that side of the home or office, pointing away from the building and not over it.

Questions & Answers


Ask a Question
  • For the cost, wouldn't it be better just to switch carriers to get a better signal?

    Yes, if you have no contract nor obligation to current carrier, you can try changing the cell service carrier. There is indeed a slight possibility that your signal may improve due to different carrier's cell tower being closer enabling better signal penetration and coverage inside your house or office. However, in most instances, the lack of indoor reception is due to the house or building walls that prevent signals from entering indoors, regardless of the cell phone service carrier.

  • Could I use both antennas to a 2 in one splitter then to the flare booster. I receive solid 3 to 4 bars where antenna would be but 1 bar in home.

    We woudn't recommend it. The signal loss through the splitter would negate the gain of the antennas.
