3. RF EXPOSURE WARNING
In order to comply with the FCC RF exposure requirements, the BDA’s antenna installation must comply with the
following:
The outdoor antenna (Yagi type or similar directional antenna if off air donor signal used) must be installed so as to
provide a minimum separation distance of 0.3 meters (60 cm) between the antenna and persons within the area.
(This assumes a typical antenna with gain of [10.1 dBi, VSWR ≤ 1.5:1, Zo= 50 ohms, and a cable attenuation between
1-10 dB).
The indoor antenna (Omni directional or leaky cable) must be installed so as to provide a minimum separation
distance of at least 8 inches (20 cm) between the indoor antenna connected to the RF booster and the human user’s
body within the area. (This assumes a typical wide beam type antenna with gain of 0-2 dBi, VSWR ≤ 2:1, Zo= 50
ohms, and a cable attenuation of between 1-10 dB).
4. INSTALLATION
DO NOT APPLY A.C. POWER TO THE BDA UNTIL CABLES ARE CONNECTED TO BOTH PORTS OF
THE BDA AND THE ANTENNAS.
1. To mount on a wall. Using appropriate screws and anchors, attach the BDA to the wall at the four mounting
holes
2. Ensure that the isolation between the donor antenna and the service antenna is at least 15 dB greater than
the BDA gain.
3. Connect the cable from the donor antenna to the BDA connector labeled “DONOR” and the cable from the
service antennas to the BDA connector labeled “SERVER”.
4. Connect the AC power cord to the BDA and turn on the switch at the left-hand of PSU.
5. Installation of the BDA is now complete. Adjust the gain controls to suit the specific signal environment
through GUI on your PC.
- To prevent feedback, the donor and server antennas must be separated by an appropriate distance to
provide sufficient isolation. Isolation is attained by separating antennas a sufficient distance so that the
