The BT-459679 B-Flat is a shiny little black antenna that looks a little like a morse code dash. It was named after the note because it’s nice and flat. Since it’s the piece of a vehicle cell booster you’re putting out in the open, Bolton made it unassuming. It is not weak, though. With +3.3 dBi of gain, that’s providing more than double the power of the signal at the end - significantly higher than most low-profile vehicle antennas. Not only that, but its longer surface area provides a wider coverage area than default antennas.
The B-Flat antenna handles all signal in the 698-2700 MHz bandwidths. It comes with 10 feet of RG-174 coaxial cable attached and an FME-Female connector at the end. With adhesive on the back, it can easily be stuck to the side or back of a seat, or attached to an air conditioning vent.
