1FCC NOTICE
Note:
This equipment has been tested and found to comply with the limits for a Class A digital
device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide
reasonable protection against harmful interference when the equipment is operated in a
commercial environment. This equipment generates, uses, and can radiate radio
frequency energy and, If not installed and used in accordance with the instruction
manual, may cause harmful interference to radio communications. Operation of this
equipment in a residential area is likely to cause harmful interference in which case the
user will be required to correct the interference at his own expense.
Warning:
Changes or modifications not expressly approved by Kaval Telecom Inc. could void the
user’s authority to operate the equipment.

2INTRODUCTION
2.1 Scope of the Manual
This manual covers the use, operation and installation of the BDA1250 Bi-directional
Line amplifier. It consists of nine sections described below:
Section 1. FCC Notice: Note and warning.
Section 2. Introduction: Scope of the manual and overview of BDA system application.
Section 3. BDA1250 Amplifier description: Description and specifications of the
BDA1250.
Section 4. BDA Installation: Details procedures for installing of BDA1250.
Section 5. Antenna Installation: Details procedures for installing antenna.
Section 6. Maintenance and Troubleshooting: Recommendation for maintenance BDA
and resolving BDA problem.
Section 7. Standard Warranty: Warranty Schedule.
Section 8. Product Service Procedure: Return Material Authorization procedure.
Section 9. Ordering Parts and Accessories: Information ordering BDA parts and
accessories.
2.2 “Off-the air” Amplifier System Application
The Bi-Directional Amplifier is intended to extend Cellular coverage into areas with
coverage deficiency such as inside office buildings, shopping malls, hospitals etc. It is
designed to be located independent of the donor site and must be equipped with its own
antenna systems - one to communicate with the donor site and the other(s) to
communicate with portables in the shadow zone.
A typical in-building coverage extension system is shown in Figure 1-2. The head-end
subsystem, namely Kaval bi-directional amplifier, is responsible for the amplification of both
incoming “off-the-air” downlink signal and outgoing uplink signals. The in-building
distribution antenna system comprises of Coaxial cable, Signal taps, splitters and antennas to
extend coverage on every floor, basement and underground parking garage.

Figure 1-2. Bi-Directional Amplifier in RF distribution System
This distributed antenna system is based on Kaval’s patented “Tapped Radiator” RF
signal distribution approach. The technology makes use of coaxial cable with Signal
Taps strategically located and connected to Omni-directional ground plane antennas. This
technology offers flexibility in system design, installation and optimization. Once the RF
cable backbone has been installed, additional signal taps and antennas can quickly and
easily be added to a live system, without the need to take the system out of service.
Hence, new coverage areas can be added, or the system can easily be modified if the
layout should change (e.g. modernization retrofits or process modifications).

4BDA Enclosure Installation
4.1 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 BDA1250 (supplied by Kaval)
•Jumper cable (not supplied by Kaval)
•AC adapter (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 for the installation of the
BDA1250 (5.6”Wx1.6”Hx8.3”D) and free airflow is available around the unit.
•RF cables must be in place and labeled clearly as “Donor Cell Site” and “In-building”.
4.2 Mounting the BDA Enclosure
The physical installation is accomplished by mounting the BDA1250 in false ceilings, closets
or on a vertical wall. Using four mounting holes on the enclosure (5.82” x 5.125”, see figure
3-2) as a template insert four bolts to the wall. Make sure the bolts are capable of supporting
at least 5 lbs
4.3 Connecting the Coaxial cables
Connectors of the BDA are located on the front and back of the BDA1250 (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 BDA1250 connector marked
“Outdoor”
2. Connect the other end of the first jumper cable to the connector marked “Donor Cell
3. Connect one end of the second jumper cable to the BDA connector marked “Indoor”
4. Connect the other end of the second jumper cable to connector marked “In-building”
