2 INTRODUCTION
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
BDA1250
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).

4 BDA 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”
cable

4.4 Connecting the Power Cables
BDA1250 comes with AC adapter. Therefore an AC outlet providing 120 AC should be
available with 4ft of the BDA1250. If AC outlet is to be installed, 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. Connecting power cables can be
done as follow:
1.
Locate the on/off switch on the front of the BDA1250. Turn the switch to the OFF
position.
2.
Locate a nearby AC outlet and connect AC adapter to the AC outlet.
3.
Connect the DC input jack of the AC adapter to the BDA12500.
4.
Make sure the adapter cable is neatly tugged away.
5.
Turn the BDA1250 power switch to the ON position. LED should be luminous to
indicate the present of power.

5 Antenna Installation
l All Antenna Installation is to be performed by Qualified Technical Personnel
only.
l Antenna Installation Instructions and locations below are for the purpose of
satisfying FCC RF Exposure Compliance requirements.
l The Roof Top Antenna for linking to the Donor Site is a directional (high gain)
Antenna fixed-mounted physically on the side or top of a building, or on a tower. The
Antenna Gain must be no more than 10 dBi. The Roof Top Antenna location should be
such that only Qualified Technical Personnel can access it, and that under normal
operating conditions no other person can touch the Antenna, or approach within 10
meters of the Antenna.
l The In-Building Antenna connection is via a coaxial cable distribution system with
Signal Taps at various points connected to the fixed-mounted Indoor Antennae. This
is shown in the figure in the Introduction. The Indoor Antennae are simple 1/4
Wavelength (0 dBi 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 BDA1250; +28 dBm, or 0.63 Watts
EIRP. These Antennae are to be installed such that no person can touch the Antenna,
or approach within 0.2 Meters.
ANTENNA INSTALLATION
WARNING
ALL ANTENNA INSTALLATION IS TO BE PERFORMED BY QUALIFIED TECHNICAL
PERSONNEL ONLY.
ANTENNA INSTALLATION INSTRUCTIONS AND LOCATIONS ARE FOR THE PURPOSE
OF SATISFYING FCC RF EXPOSURE COMPLIANCE REQUIREMENTS, AND ARE NOT
OPTIONAL.
ALL ROOF TOP ANTENNA INSTALLATION MUST BE SUCH THAT NO PERSON CAN
TOUCH THE ANTENNA, OR APPROACH CLOSER THAN 10 METERS.
ALL IN-BUILDING ANTENNAE INSTALLATIONS MUST BE SUCH THAT NO PERSON
CAN TOUCH THE ANTENNAE, OR APPROACH CLOSER THAN 0.2 METERS.

6 Troubleshooting and Maintenance
6.1 Maintenance
6.1.1 Maintenance & Safety
The BDA has been engineered for easy maintenance and for safe operation. This has
been achieved as follows:
lBDA1250 provides fault monitoring and accurate status report through LED.
lThe AC adaptor is over-rated for actual requirements.
lComponents are easily removable via quick AC adaptor DC and RF connectors.
6.1.2 Maintenance Philosophy
Field maintenance should require a screwdriver, a multi-meter, spares AC adaptor and
Portable Radio to monitor off the air signals. There is no requirement to have any test
equipment to accomplish most service repairs.
l BDA component parts have been designed for reliable long life operation.
lCorrective action can often be taken without detailed technical knowledge or the
need for any test equipment.
6.2 Troubleshooting Procedure
