Flare is the first cellular phone signal booster with a combined indoor antenna and signal booster, simplifying setup and increasing signal strength for multiple simultaneous users on all North American cellular carriers, including AT&T, Verizon, T-Mobile and Sprint. Flare's revolutionary design features a built-in indoor omnidirectional antenna that increases signal strength for voice, text and 4G LTE data in 12 rooms of a home or office, up to 2,500 sq. ft. The attractive 1-piece base unit is designed to be placed on an open tabletop or shelf for clearer, more reliable voice and data performance in any room. Signal is delivered to the Flare booster with the included omnidirectional outdoor antenna and 50 ft. of low-loss RG6 cable. The outdoor antenna captures signal from the cellular tower and Surecall's award-winning, patented, all-carrier booster amplifies it and rebroadcasts the enhanced signal coverage to all mobile devices within range.
