98-175666-D Appendix B: Dual antenna solution B-5
Configuration of the dual antenna solution
On the DASHBOARD, section SYSTEM INFO, there is a link saying Slave ADU or Master
ADU where you can switch between the master/slave dashboard. Below the top bar
you can see whether the current system is active or not.
The dual-antenna system switches between the 2 antennas in the following scenarios:
• When in a programmed blocking zone.
• When the signal for the active antenna is blocked for more than 2 minutes.
• Malfunctioning ADU.
• When signal strength drops 4 dB lower than the in-active antenna.
