Description of the system components
2.2.1
Antenna positioner
The auto-acquire antenna positioner can accommodate 0° to 88° of angular movement in
the elevation axis and ±95° in the azimuth axis. The mechanical assemblies rely on two
independent axes to allow for precise antenna pointing. A ground gradient of up to 10° can
be accommodated by the terminal. The antenna positioner can stay outside in rainy
weather

RF assembly
The RF assembly for EXPLORER 6075LX includes the BUC, LNB, reflector hub, filter/polarizer,
and Ka feed horn. It also contains brackets that are attached to mounting blocks on the
elevation arms. Once the RF assembly is mounted, the thumb screws beneath the blocks
hold the brackets securely in place. Also, the BUC and LNB are mounted closely to the
filter/polarizer to reduce the need for wave guides. This design allows for quick assembly
and disassembly of the RF assembly from the positioner.
Note
If the elevation angle is less than 10 degrees it is important to level the terminal.
