3. Inspection and Installation
Inspection
Inspect the equipment as soon as possible after purchase. If any part of the
equipment has been damaged in transit, report the damage to the
transportation company and also to the company where purchased.

Exterior High Gain Antenna
Interior Omni Antenna
Installation
Note:
The Installer should refer to the Safety Precautions, in the following section,
for proper antenna selection and installation
The installation of the Mini-IBA is relatively simple. If possible,
measurements of the Received Signal Strength Indicator (RSSI) should be
recorded as close as possible to the proposed exterior antenna location.
Optimum performance will be obtained with RSSI readings greater than –85
dBm.
With the exact location of the exterior antenna and the coordinates of the cell
sits closest to the building in which the unit is being installed, the distance
and bearings to each of the local cells can be determined. The first choice
would be the closest site unless there is blockage in the form of buildings or
terrain. If blockage exists, an alternate site may be available.

If coordinates are not available, measure the RSSI at the external antenna
output by connecting a phone to the external antenna and slowly rotating the
antenna until a maximum reading is obtained.
The Mini-IBA and interior antenna should be centrally located, keeping
coaxial cable runs to a minimum. A maximum length of 100 feet of low loss
cable is recommended. The actual coax used should be RG-8 type with a
flame retardant rating as a minimum. If the coax is run through an area
where heating and/or cooling air is channeled, a plenum rated coax should
be used. When mounting the amplifier, take care to avoid areas of high heat
or extreme cold. In general, do not place the unit on or near the top of high
ceilings, by heaters or in cold storage areas.
During installation, care must be taken to provide the maximum isolation
between interior and exterior antennas. This isolation should be at least 70
dB to prevent any re-generative feedback in the system. Feedback of this
nature may cause the amplifier to emit a continuous signal at maximum
amplitude and could, in some cases, interfere with the normal operation of
the cell site.
There are no installation or user adjustments or tuning on this unit.

Safety Precautions
CAUTION
For INDOOR use, an Omni-Directional Antenna with a maximum gain of 8dBi 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, a Directional Antenna up to a maximum gain of 13dBi is
authorized for use with this unit.
The Outside antenna 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 in.) from the
outside antenna. In all installations, the antenna should never be mounted
such that the main beam is directed toward an area where workers or
bystanders may be present. Exceeding this minimum separation will
ensure that the worker 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.
