Q. Where do we install the antennas for In-vehicle BDA applications?

The two antennas that are connected to the amplifier need to be a certain distance apart. If they are too close, the amplifier will automatically reduce the gain to prevent signal oscillation (similar to microphone feedback). The Green SST® LED on the amplifier would be blinking red if the antennas are not properly separated.

Q. How do I know if I have enough outside signal for my In-building BDA?

Turn on your cell phone, and if you can log on to your cell carrier you have enough signal.

Q. What is the difference between the SBX Amplifier and the In-vehicle Bi-directional Amplifiers (BDA)?

SBX Amplifiers can be used with a hands-free car kit or direct connect cable to the cell phone or the Boston Amplifier In-Vehicle Antenna. If used with the In-Vehicle Antenna the cell phone must be in a cell phone cradle with the In-Vehicle Antenna on the inside of the windshield or the side panel of the windshield.

Bi-directional Amplifiers are wireless amplifiers and need no direct connection to the cell phone.

Q. What is included with each Booster Amplifier or Bi-directional Amplifier?

See individual data sheets for what is included with each model.
