•
Follow all local safety regulations when installing the system.
•
Follow Electro-Static Discharge (ESD) precautions.
•
Install the DMSB 700/800 MHz amplifier close to the service area to monitor
the output power and noise figure.
•
It is recommended that the installation location be as close as possible to the
antenna site in order to minimize cable loss.
•
Use low loss cables to perform the RF connections
•
Install the units (or place the cabinet with installed units) in a shielded and
ventilated area.
•
Only trained and qualified personnel should be allowed to install or replace this
equipment.
•
Verify that ambient temperature of the environment does not exceed 50
°
C
(122
°
F)
•
Ensure that adequate airflow and ventilation within the rack and around the
installed components so that the safety of the equipment is not compromised.

The Base (Donor) antenna is usually installed outdoors and is either a directional
antenna such as a Yagi or a Panel antenna.
Donor Antenna specifications:
•
Yagi type or similar – 10 to 15 dBi gain, very sharp beam pointed to the BTS.
•
Cable and jumper loss is at least 2dB.
•
The required Base signals should be the dominant signals; at least 6 dB higher
power than other signals.
•
Example of antenna's typical specifications:
Gain:
8 dBd (=10 dBi)
VSWR: <
1:5:1
Impedance: 50
ohm

The Mobile antenna is installed indoors.
Note: Before installing the Mobile antenna, see FCC regulations for information
regarding recommended distances between the antennas and populated areas.
The following describes the requirements for an omni-directional mobile used for
indoor applications.
