3. Elevate the ADU by mounting it on a mast or on a mounting pedestal on a deck or
deck house top to avoid obstruction.
Blocking zones – azimuth and elevation
The installation may require to set up blocking zones for the ADU, i.e. areas where the
ADU will not transmit and areas where transmit power is potentially dangerous for
persons frequently being in these zones. 8 blocking zones can be set up. Each blocking
zone is set up with azimuth start and stop, and elevation angle. The blocking zones are
set up in the built-in web interface of the BDU.
