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 (received signal of -40dBm at the antenna port), the
SNR should not be higher than 50dB. The orange LED of the SNR bar indicates that the
SNR is higher than 50dB.
