Procedure
Warning; Equipment Installation:
 Proper Grounding
 Follow the local building codes for installation of antennae on buildings.
 Ensure that the exterior mounted donor antenna is properly mounted and
grounded for lightning protection.
 RF exposure Guidelines
 During transmitter operation, in order to meet RF Maximum Permissible
Exposure Safety Guidelines, a minimum distance of 50 cm (20 in.) shall be
maintained between the outdoor (uplink) antenna and personnel.
 During transmitter operation, in order to meet RF Maximum Permissible
Exposure Safety Guidelines, a minimum distance of 20 cm shall be maintained
between the indoor antenna and personnel.
 The maximum cellular outdoor (uplink) antenna gain authorized shall be limited to
18 dBi or less in order to meet RF exposure (MPE) limit as per FCC guidelines.
 The maximum cellular indoor (downlink) antenna gain authorized shall be limited
to 9 dBi or less in order to meet RF exposure (MPE) limit as per FCC guidelines.
 When servicing or installing outdoor transmitting elements (i.e. antennae), all
transmitting signal sources should be turned off in order to meet RF exposure (MPE)
limit as per FCC guidelines.
The repeater unit should be installed in a sheltered area, it’s operating
temperature range is extensive, but is not sealed to prevent water (rain)
ingress. The repeater unit should not be installed in an area where the
ambient temperature is expected to exceed +60°C.
The SignalReach CR100 is not supplied with cabling or any antennae. The
indoor and outdoor antenna types and locations must be chosen carefully to
avoid re-generative feedback. Re-generative feedback occurs when the
subscriber antenna picks up the donor antenna transmit signal. A general
rule of thumb is to locate the antennae where the isolation is at least 10 dB
greater than the operating repeater gain. The Arrista repeater has a
maximum gain of 60dB in uplink path, as a result, the isolation required
between the subscriber and the donor antenna is in a range of 70dB. The line
of sight separation between the subscriber and donor antenna represented by
a free space loss of 70dB within a building is 17 meters (55 feet). The
separation distance can be reduced if the donor antenna is mounted on the
building exterior (i.e. on a roof), or by using a directional donor antenna
