The repeater gain must be set to at least 10 dB below the measured isolation. For
example, if the measured antenna isolation is 90dB, the repeater gain should be set for
no more than 80 dB.
3.4 Repeater Mounting
These recommendations should be followed for best repeater performance:
The repeater should be mounted so the heatsink avoids direct sunlight. This will
help improve the lifetime of the repeater.
The repeater must be mounted upright so that the connectors are on the
underside. This will help prevent a buildup of moisture inside the repeater.
The repeater is equipped with N female (optionally, DIN 7-16) antenna
connectors. Connectors are located at the bottom of the unit.
Ensure that adequate room has been allocated for the bending radius of the
cables. Refer to the cable manufacturer’s specifications for the allowable cable
bend radius.
Ensure that adequate room is allowed for the opening and closing of the repeater
door. See the specification table for dimensions of the repeater.
