What’s Bi-Directional Amplifier BDA?

A Bi-Directional Amplifier (or BDA) is used for On-Site radio coverage enhancement of RF signals in buildings, tunnels or areas that are shaded. BDA ‘s have a few components: A donor antenna collects signal from the rooftop where it is strong and delivers it to the BDA for amplification. The amplified signal is delivered to one or more distribution antennas in areas which have poor coverage. BDAs are available in many specific bands: VHF, UHF, 700MHz, 800MHz, and cellular/LTE etc.

Kingtone Customized 136-174MHz VHF Band Selective Bi-Directional Amplifier BD take incoming signals within a band and amplify them for distribution in another area. Bi-directional amplifiers are really just 2 amplifiers in one package; one for amplifying signals from the cell or repeater, the other for amplifying signals from the mobile device to the radio network.

Most places have some signal, just not in all the areas required on site. For example, a hotel may have signal on the upper floors, but not in the parkade. To provide signal into the parkade, we would install an antenna to pick up signal from the cell site or repeater from working areas, feed it to the amplifier then off to more antennas located near the areas with deficient coverage. coverage.
