Page 3: Mini-Bda Overview
Mini-BDA OVERVIEW: The Mini-BDA assembly extends the coverage area of radio communications in buildings and RF shielded environments. The Mini-BDA has dual RF paths to extend coverage in two distinct frequency bands. The unit features low noise figure and wide dynamic range. It is based on a duplexed path configuration with sharp out of band attenuation allowing improved isolation between the receiving and transmitting paths. -

Page 9: Rf Exposure Warning
RF EXPOSURE WARNING In order to satisfy the FCC RF exposure requirements, the Mini-BDA/antenna installation must comply with the following: The outdoor antenna (Yagi type or similar directional antenna) must be installed so as to provide a minimum separation distance of 0.3 meters (30 cm) between the antenna and persons within the area. -
Page 10: Mini-Bda Installation
Mini-BDA INSTALLATION DO NOT APPLY A.C. POWER TO THE Mini-BDA UNTIL CABLES ARE CONNECTED TO BOTH PORTS OF THE Mini-BDA AND THE ANTENNAS. 1. Mount the Mini-BDA on the wall with the RF connectors pointing DOWN. Using appropriate screws and anchors, attach the Mini-BDA to the wall at the four mounting holes on the side flanges. -
Page 11: Mini-Bda Operation
Mini-BDA OPERATION Refer to figure 3 and 4 for adjustment access location and label. Variable Step Attenuator Mini-BDA gain can be reduced by up to 30 dB in 2 dB steps using the variable step attenuator. Gain adjustment is made with rotary switches accessible from the top of the Mini-BDA enclosure (See Figure 4). -
