Background
Satellites used for television signals are 22,300 miles (37,000 km) above the earth’s equator. The purpose of the Vu Qube is to acquire the signal traveling that great distance and transmit the signal to the digital receiver in your vehicle, so you can watch TV anywhere you park.
Satellite television, like other communications relayed by satellite, starts with a transmitting antenna located at an uplink facility on Earth. The uplink dish is pointed toward a specific satellite and the uplinked signals are transmitted. The signal transmitted to the satellite is within a specific frequency range and is received by one of the transponders tuned to that frequency range aboard that satellite. The transponder then transmits the signals back to Earth but at a different frequency band (to avoid interference with the uplink signal). The leg of the signal path from the satellite to the receiving Earth station, in this case the Vu Qube, is called the downlink.
The downlinked satellite signal, quite weak after traveling a great distance is received by the Vu Qube antenna, which reflects the weak signal to a focal point that gets transferred to a feedhorn. The receiving antenna must have a clear view, without obstruction, of the southern sky to maximize the signal acquired. This signal is then amplified and converted by the LNBf
