Normally, it is not necessary to modify the sensors on the antenna. The antenna manufacturer will
insure that the antenna is compatible with the RC3050. This information is provided for informational
purposes only.
The directional sense of azimuth movement is defined as clockwise (CW) or counter-clockwise (CCW)
as viewed by an observer located above the antenna. On the controller CW movement results in a
greater sensed azimuth position.
The directional sense of polarization movement is defined as CW or CCW as seen by an observer
standing behind the antenna reflector looking 'through' the reflector at the satellite. The reference
position for the polarization position angle is vertical polarization for a satellite located at the same
longitude as the antenna. In the northern hemisphere, for vertically polarized satellites to the west of the
antenna, the polarization deflection is defined as CW relative to the reference position. In the northern
hemisphere, the polarization angle increases for satellites farther to the west.
