Figure 5: External LED Indication and Manual Gain Attenuation Access INSTALLATION DO NOT APPLY A.C. POWER TO THE UNIT UNTIL CABLES ARE CONNECTED TO BOTH PORTS OF THE BDA AND THE ANTENNAS. Set the BDA on the floor or mount on a wall (where applicable). Using appropriate screws and anchors, attach the BDA to the wall at the four mounting holes on the side flanges. -
Page 14: Operation
Verify the downlink in-building signal strength and the uplink signal strength at donor antenna meets requirements. Reduce the gain if needed (increase attenuation). Note: Operation of BDA-PS9-37/37-90-C at maximum gain with greater than -30 dBm average power incidents on the MOBILE or BASE ports could cause damage to the BDA. -
Page 15: Diagnostics Guide
DIAGNOSTICS GUIDE The BDA provides long term, care-free operation and requires no periodic maintenance. There are no user-serviceable components inside the BDA. This section covers possible problems that may be related to the installation or operating environment. Gain Reduction Possible causes: Defective RF cables and RF connections to antennas, damaged antenna or Leaky cable Occasional Drop-out of some Channels Possible causes: One channel with very strong power dominates the RF output of the... - Page 16 APPENDIX 1 26-Pin Connector Mobile Antenna Failure contacts are not standard in the O26 pin- out and must be requested at time of order to be included.
