5 BDA Enclosure Installation
5.1 Preparation for the installation of BDA enclosures
a. Equipment and hardware required
• Each BDA is carefully packaged for air shipment. Any damage incurred during the transportation must be
claimed from the shipper.
• Make sure the following necessary equipment and hardware are available and undamaged.
• 1 BDA enclosure (supplied by Kaval)
• 2 50-ohm jumper cables (not supplied by Kaval)
• 1 12’ AC power cord (not supplied by Kaval)
• AC Outlet is nearby (not supplied by Kaval)
• Padlocks, optional (not supplied by Kaval)
•
Mounting hardware such as: Four washers and four bolts (not supplied by Kaval)
b. Preparing the installation site
•
Make sure the mounting area is large enough to accommodate the installation of the BDA enclosure
(17”Wx16”Hx10”D) and free air flow is available on both sides of the cabinet.
• RF cables must be in place and labeled clearly as “Donor Cell Site” and “In-building”.
5.2 Mounting the BDA Enclosure
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. Using four mounting lugs on the enclosure (see figure 3.1) as a template insert four bolts to the wall.
Make sure the bolts are capable of supporting at least 70 lbs. BDA Enclosure can be mounted as described
below:
1. Raise the BDA enclosure so that the BDA enclosure is about 1” to 3” away from the bolts so that one can
see the bolts through the larger diameter of the keyhole slots, see figure 3-1.
2. Move the BDA enclosure closer to the wall so those four keyhole type slots are hooked onto the bolts.
3. Slide the BDA enclosure down until all bolts fit well in the narrow part of the keyhole slots.
5.3 Connecting the Coaxial cables
Connectors of the BDA are located on the bottom of the BDA enclosure (see figure 3-2). RF cables can be
connected to these connectors using jumper cables as follows.
1. Connect one end of the first jumper cable to the BDA connector marked “Downlink Antenna.”
2. Connect the other end of the first jumper cable to the connector marked “Donor Cell Site” antenna.
3. Connect one end of the second jumper cable to the BDA connector marked “Uplink Antenna.”
4. Connect the other end of the second jumper cable to connector marked “In-building” cable.
