should use the same antenna to avoid unexpected problems occurred in the operation.

Step1: Mount your antenna and ODU in the appropriate position. The correct position depends on your needs. You
should also take the distance between antenna and ODU into consideration. The distance is larger, then you need a
longer cable to connect which usually stands for higher cable loss.
Step2: Turn off you power of the system.
Step3: Correctly connect your cable between ODU and antenna.
Step4: Turn on the power of the system with SSPA function off. Try to adjust antenna angle by checking the LED
light number or RSSI voltage to achieve the best performance. This step would decrease the power to the minimum
level so that it won’t harm the installer.
Step5: When best performance is achieved, then turn on the SSPA function to make the transmission better to avoid
air interference or weather attenuation. Then the antenna installation is completed.
