Optional Accessories
•
Inadequate isolation between the outside and inside antennas may cause regenerative feedback in the system. This feedback can
cause the amplifi er to emit a continuous signal at maximum amplitude and, in some cases, interfere with normal operation of the donor
site. Careful consideration of the layout and placement of the system is imperative to minimize this possibility and to minimize the amount
of signal leaking from the building. See installation tips below for general guidelines.
•
The installer should refer to the Safety Guidelines section on page 4 and the Important Safety Information section on page 5 for
proper antenna selection and installation. To avoid serious injury or death and damage to the repeater, do not install donor or server
antennas near overhead power lines or high power components. Allow enough distance so that if antennas should fall they will not come
in contact with those components.
•
Close proximity to the donor or server antennas with the repeater in operation may expose the user or installer to RF fi elds that
exceed FCC limits for human exposure.
WARNING!
AMPLIFIER OR HANDSET DAMAGE
MAY
OCCUR IF A HANDSET IS CONNECTED DIRECTLY TO THE REPEATER
OR THE COAX THAT LEADS TO THE REPEATER.
Important Installation Notes
Donor Antenna
1.
Accurately determine the azimuth to the donor cell site .
Obtain the donor site information and approval from the
service provider/carrier.
2.
Ensure that the radiation path to the donor cell site is as unobstructed as possible.
3.
Mount the donor antenna at or toward the edge of the roof, in the direction of the donor site. Try to avoid having the RF
signal from the donor pass above the location(s) of the service antennas. Normally the service antennas will be behind
and below the donor antenna if viewed from above. This approach will help avoid interference and feed back both, to and
from the service antennas.
4.
Normally mounting the donor antenna higher will allow a less obstructed path to the donor site. However, in high traffi c
metro areas avoid mounting the donor antenna any higher than necessary as the quality of the donor signal may start to
become less stable and it is more likely to encounter adjacent channel interference.
5.
When possible shield the donor antenna’s back side by locating it so that any HVAC units and/or penthouse structures are
behind the antenna relative to the donor cell site location.
Installation Tips
Indoor Antennas
1.
Use omnidirectional antennas (see optional accessories) indoors, and locate them centrally with respect to the intended
coverage area to minimize signal leakage to the outside. Use directional antennas indoors only in special cases when higher
gain and directionality would be helpful and RF exposure limits will not be exceeded.
2.
To avoid repeater uplink overload and gain limiting mount the indoor antennas away from areas where mobile subscribers
frequently use their phones such as desks or dispatch areas.
