2.5. Loss of satellite due to blockage or rain-fade
If tracking is lost due to blockage or rain fade, the antenna will search until a signal is found which is high
enough for the antenna to begin tracking. When the receiver interface is operating properly, the antenna will
automatically continue searching until it has acquired the desired satellite.
2.6. 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.
2.7. Radome Assembly Operation
When operating the system it is necessary that the radome top be properly installed 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 and wind gusts would disturb the antenna pointing.
There are no other operating instructions applicable to the radome assembly by itself.
