◆ The weak input signal leads to the low output power. Change the direction of donor antenna or its
installation position or replace donor antenna with higher gain antenna to increase input signal power
level.
◆ Check whether it is necessary to add more server antennas since barriers block the signal penetration,
also check whether the repeater’s power is enough; please install more server antennas or replace with
a repeater of higher power level.
2) If the signals in small part of the areas have not been improved, please check below:
◆ Check whether the service antenna is installed correctly or not, you may try to move the antenna
location to improve coverage.
◆ Check if it is necessary to adjust the direction of the sever antenna.
◆ Check whether it is necessary to add one or more antenna to enhance the coverage of special areas.
◆ Remark:
 Reduce the attenuation values*---at the same time must ensure the isolation.
 Increase the output power* ---recommended ways: adjust the donor antenna direction /
