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.
