Elevation Offset
The rotator also provides a greater elevation range than the 180 degrees required by
the user. This full mechanical rotator range is determined by the rotator control unit
during calibration. By using the elevation offset setting, the user can place the
required 0-180 degree range in the centre of the full mechanical range. The
maximum elevation offset achievable in either direction is determined as:
Maximum elevation offset = ((Full mechanical rotator elevation range)-180)/2
The WR-ARP-ELAZ-100 rotator has a full mechanical rotator elevation range of
around 200 degrees, giving it an over-travel of about 20 degrees, and hence an
elevation offset range from approximately -10 to +10 degrees. A positive value for
offset will rotate the antenna upwards with respect to the lower travel range reference
point on the user interface, while a negative value rotates it downwards (if current
elevation < 90 degrees).
