Where To Buy

Turn Your Minor Signal Major with the Bolton B-Flat

The Bolton B-Flat is a shiny little black antenna that looks a little like a morse code dash, or one of those Wii sensor bars you had to stick on the top of your TV back in the day. We named it after the note because we thought of, it’s nice and flat. Since it’s the piece of a vehicle cell booster you’re putting out in the open, we thought it best to make it unassuming. .

Don’t make the mistake of thinking this baby is 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 an attached 10 feet of RG-174 coaxial cable with 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.

You have questions. We have answers.

What Kinds of Signal Does the Bolton B-Flat Broadcast? What Radio Bandwidths?

The Bolton B-Flat broadcasts any signal between the 698-2700 MHz bandwidths. That includes all 4G/LTE/3G cellular signal. This covers all US carriers (AT&T, T-Mobile, Verizon, U.S. Cellular and more), Canadian carriers (Rogers, Bell, Telus, more), Mexican carriers (Telcel, Movistar, AT&T Mexico), and far more.

However, all this is dependent on what your donor (outdoor) antenna(s) is capturing. While the B-Flat is a powerful vehicle antenna at point of broadcast, it cannot create high-quality or strong signal on its own.

What Does dB Mean? What About Gain?

dB refers to the power gain of the antenna, and the higher the number, the more powerful the antenna. As dB is measured on a logarithmic scale, every +3 dB represents a doubling of the power gain.

Will the Bolton B-Flat Work with My Carrier?

The B-Flat will work on any US or Canadian carrier, as well as most cellular carriers worldwide. If you are not sure your country’s carrier will work with the Bolton B-Flat, verify whether your service falls within the 698-2700 MHz bandwidth, and if so, it will work.
