Just carefully re-read the first post. Cambium’s already confirmed that the downtilt is the total mechanical + electrical tilt. If you think about this, logically it makes sense. Electrical tilt has a direct effect on the coverage area of the sector… same as mechanical tilt. Why wouldn’t the SAS require both?
You can find further discussion and confirmation of the electrical + mechanical downtilt needing to be included, confirmed by a Cambium employee HERE.
