Important Installation Notes 
 
•  A high degree of isolation must be afforded to prevent any re-generative feedback in the system. Feedback of this nature 
causes the amplifier to emit a continuous signal of maximum amplitude and could, in some cases, interfere with normal 
operation of the cell site. The minimum required isolation of 80 dB can usually be obtained by mounting the outside antenna 
away from the edges of the roof. The use of window mounts or other non-rooftop mountings should be avoided. 
• 
The Installer should refer to the Safety Precautions, in the following section, for proper antenna selection and 
installation 
 
Warning! Amplifier Damage will occur if a handset is connected directly to the BDA or the coax that leads to the 
BDA. 
 
Important Safety Information 
 
For INDOOR use, an omni-directional antenna with a maximum gain of 3 dBi is authorized for use with 
this unit. Inside antennas must be positioned to observe minimum separation of 20 cm. (~ 8 in.) from all 
users and bystanders. For the protection of personnel working in the vicinity of inside (downlink) 
antennas, the following guidelines for minimum distances between the human body and the antenna must 
be observed. 
 
The installation of an INDOOR antenna must be such that, under normal conditions, all personnel cannot 
come within 20 cm. (~ 8.0 in.) from any inside antenna. Exceeding this minimum separation will ensure 
that the employee or bystander does not receive RF-exposure beyond the maximum permissible 
exposure according to section 1.1310 i.e. limits for General Population/Uncontrolled Exposure. 
 
For OUTDOOR use, an omni-directional antenna with a maximum gain of 3 dBi is authorized for use with 
this unit. Outside antennas must be positioned to observe minimum separation of 20 cm. (~ 8 in.) from all 
users and bystanders. For the protection of personnel working in the vicinity of outside (uplink) antennas, 
the following guidelines for minimum distances between the human body and the antenna must be 
observed. 
 
The installation of an OUTDOOR antenna must be such that, under normal conditions, all personnel 
cannot come within 20 cm. (~ 8.0 in.) from any outside antenna. Exceeding this minimum separation will 
ensure that the employee or bystander does not receive RF-exposure beyond the maximum permissible 
exposure according to section 1.1310 i.e. limits for General Population/Uncontrolled Exposure.
