Page 4: Introduction
• INTRODUCTION This Operator’s Manual covers the use, operation and installation of the BDA1200 800 & 900 MHz Bi-Directional Amplifiers (BDA’s). BDA’s are intended to extend radio frequency coverage into areas with coverage deficiency such as inside office buildings, shopping malls, hospitals, tunnels etc. They are designed to be located independent of the Donor Transceiver Site and are equipped with their own antenna systems - one to communicate with the Donor Transceiver Site and the other(s) to communicate with radio equipment in the area with coverage deficiency. -

Page 9: Bda Controller Operation
BDA CONTROLLER OPERATION The BDA Controller is a microprocessor based part of a Kaval BDA that provides all control, fault monitoring, and settings for the BDA. It interfaces to the 28 VDC Power Supply, the optional 24 VDC Battery (both monitoring, transferring, and charging), control signals to the Boosters, and provides monitored DC power for the Boosters and PA’s. -

Page 16: Installation
The physical installation is accomplished by mounting the enclosure onto a vertical wall. Ensure that the unit is mounted in the upright position, as indicated by the upright Kaval logo and the door hinge on the left side of the housing. Four mounting lugs on the enclosure provided for this purpose. -

Indoor Antennae. This is shown in the figure in the Introduction. The Indoor Antennae are simple 1/4 Wavelength (0 dB Gain) types. They are used with Kaval 12, 16, or 20 dB Cable Taps. As such the maximum EIRP will be at the first Tapped Antenna, which will be 12 dB below the maximum signal level of the BDA1200 (+40 dBm with Booster &... -
