2.2 Surge Protector Installation
Connect the cable run to the antenna and pass it through the roof manifold. Inside of the
building find a location for the surge protector near the construction ground where it can
be reliably grounded.
Install the surge protector and connect the cables to both sides. Bring the cable run to the
BDA location. Using a spectrum analyzer or mobile phone, measure the signal from the
"donor" site. It has to be from 1 dB to 3 dB below the antenna output level. Exact loss
depends on the cable type and length of the cable.
2.3 Indoor Antenna (s) Installation.
From preliminary evaluation of the blueprints of the service area, the approximate
locations of the indoor antennas must be established. The level of the signal at the
boundary of the service area can be a guideline for the location of the antennas. Several
parameters must be considered:
a) the gain of the Omni antenna is 0 dBd.
b) the free space propagation loss is approximately -60 dB per 100 ft.
c) the acceptable level at the lowest signal position for the mobile is -80 dBm.
Following the installation instructions mount antennas at the ceiling tiles or any other
appropriate locations. Run the cables from antennas to the BDA location. Use power
combiner, if needed, to interconnect the antenna cables.
CAUTION: A minimum separation distance of 20
centimeters between the transmit antenna and
nearby persons must be maintained. If this
separation distance is not maintained, the device
may not be in compliance with FCC RF Exposure
rules.
2.4 BDA Installation
The bi-directional amplifier can be installed as a freestanding unit lying on the shelf of
the cabinet or any other adequately strong support. It can also be secured by screws to the
wall or rack using four holes in the tabs located at the back plate of the enclosure. AC
power must be available in the vicinity of the BDA. It is recommended that the
environmental temperature will not exceed 65 C and the area will be adequately
ventilated.
Once amplifier is installed in place, open the front door and verify that all internal parts
are securely mounted. Connect the ground wire to the ground stud on the enclosure.
Plug in the AC cable into the AC socket. The green light on the enclosure must be lit on.
a) Downlink Gain Setting.
Connect the cable from the lightning protector and “DONOR” antenna to the “DONOR”
port of the BDA.
Connect a power meter or spectrum analyzer to the "SERVICE" port (Uplink input
connector) of the BDA. Measure the power of the signal at the “SERVICE” port of the
BDA.
