• Coordinate (m) : This field allows you to insert the
values of the set T or L co-ordinate. Remember to
indicate if a coordinate is negative. Check the current
T or L coordinate on the site and insert it into the
relative field Remember that, despite the actual
dimensions of the antenna box, it is represented in
the Cartesian reference system by a single point that
corresponds to its centerpoint. When moving the
antenna box, make sure the centerpoint is on the scan
line, at the defined coordinate.
o Coord. value : insert the value of the coordinate
to be maintained constant during the scan in this
field.
o Coord. Step : this field contains the step value
that is added automatically to the current value
when a scan is finished, leaving the system
ready to start the next scan. The preset value = 2
m between scans. For example, if a longitudinal
scan has been chosen and it starts from a point
with coordinates T, L = 0 ;+2 m, the following
values must be set:
