4 Rotate the antenna until the maximum SNR reading is achieved, where at
least 1 green LED is on. If you encounter prolonged difficulty in illuminating
the minimum required number of green LEDs, try to improve the reception
quality by placing the antenna at a higher point or in an alternate location.
5 Ensure that the front of the antenna is always facing the Base Station.
However, in certain conditions, such as when the line of site to the Base
Station is hampered, better reception may be achieved using a reflected signal.
In this case, the antenna is not always directed toward the Base Station.
6 Secure the unit firmly to the pole.
NOTE
In some cases, the antenna may need to be tilted to ensure that the level at which the SU receives
transmissions from the AU (and vice versa) is not too high. As a rule of thumb, if the SU is located at
a distance of less than 300 meters from the AU, it is recommended to up-tilt the antenna by
approximately 10° to 15°. To guarantee a safety margin from the saturation level, the SNR should
not be higher than 50 dB. The orange LED of the SNR bar indicates that the SNR is higher than 50
dB.
