INSTALLATION
l
Upon receiving the BDA shipment, examine the packaging and the Cabinet for damage.
l
Each BDA is carefully packaged for air shipment. Any damage incurred during the transportation must be claimed from the
shipper.
l
The BDA is fully contained in a single Nema-style wall mountable cabinet.
l
Prior to installing the Roof Top Antenna and the Distribution Antenna System make sure that enough Antenna Isolation. If
there is insufficient Isolation between the antennas, the amplifier gain must be set to a minimum of 12dB lower than the
available Antenna Isolation. As a rule, this is easily achievable with in-building installation.
l
Check for and remove all packing materials prior to installing this unit.
l
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. The cabinet is equipped on the left and right sides with an intake ventilation air at
the bottom and exhaust fan at the top. Ensure that free air flow is available on both sides of the cabinet.
l
The AC electrical wiring is accessible via an opening at the bottom left hand side of the cabinet. The AC Terminal Strip is
provided at the bottom of the cabinet:
Connection
Hot Line
Neutral Line
Ground connection
It is highly recommended that AC Power Wiring be performed by a qualified Electrician so as to ensure compliance with all
National and Local Electrical Wiring Regulations.
l
AC Power and RF Connections should be installed with all standard installation practices for lightning protection. This includes
the grounding and electrical bonding together of all equipment racks and cabinets in the room. It also includes a grounding of
the primary antenna cable and the installation of proper surge suppression (lightning arrestor) equipment at the entrance to the
equipment room.
l
Connect the Roof Top Antenna feeder cable to the "Donor Cell Site" Antenna.
l
Connect the Distribution Antenna System feeder cable to the "In-building Antenna" port.
l
Make sure that the BDA Controller Power On/Off Switch is "Off". Activate the circuit breaker or plug in the AC. The BDA
Controller should light up momentarily then shut off. Turn the BDA Controller Power On/Off Switch to "On". The BDA
Controller screen should become active, and Cooling Fans should be running. Check the BDA Controller for any reported
Fault conditions.

FIELD ADJUSTMENTS
The proper operation of the BDA in providing RF coverage extension is a function of not only the BDA, but also of proper systems
engineering including isolation measurements and in building RF distribution design. The most critical requirement for the BDA
installation is that the isolation between the "Roof-Top" Antenna and the in-building Antenna distribution system exceed the overall
BDA System Gain by at least 12dB. The actual gain requirement for each Installation must be determined by the available antenna
isolation and the operational requirements determined by local Systems Engineering.
Each BDA has a Factory determined minimum gain both for the Uplink and Downlink Paths. The final Path Gain from Antenna Port
in to Antenna Port out, is set by the BDA Controller.
Follow through the BDA Controller Menus to set all configurable items as are appropriate for the installation.
