be operated manually from the ACU for diagnostic or alignment purposes. Refer to the Antenna Control Unit manual
for more operation information.
2.7. Low Noise Block Converter Operation
There are no operating instructions or controls applicable to the LNB. This unit is energized whenever the matrix
switch and satellite receiver(s) have AC power connected to them.
Satellite signals are either circular polarized (spiraling plane down from the satellite) or linear polarized (fixed plane
down from the satellite). The pedestal will receive circular polarization signals when a circular LNB is installed on the
back of the dish. Conversely, the pedestal will only receive linear polarized signals when a linear LNB is installed.
2.8. Radome Assembly Operation
When operating the system it is necessary that the radome access hatch (and/or side door) be closed and secured in
place at all times. This prevents rain, salt water and wind from entering the radome. Water and excessive
condensation promote rust & corrosion of the antenna pedestal. Wind gusts will disturb the antenna pointing.
There are no other operating instructions applicable to the radome assembly by itself.
