摘要:
Disclosed is a satellite communication antenna, including a signal transmitting/receiving section for receiving signals from a satellite and transmitting the signals to the satellite; a driving section for rotating the signal transmitting/receiving section so that the signal transmitting/receiving section tracks the satellite; a main post, provided in a longitudinal direction, for supporting the driving section; and a vibration absorption section, provided to a circumference of the main post, for preventing vibrations or impacts from transferring into the signal transmitting/receiving section, thereby to attenuate vibrations or impacts acting on the signal transmitting/receiving section in up and down direction.

摘要:
There are provided a polarizer rotating device and a satellite signal receiving apparatus having the same. The satellite signal receiving apparatus includes a feedhorn that receives a satellite signal; a low noise block down converter that processes the signal received by the feedhorn; a skew compensating device that is provided at the low noise block down converter or the feedhorn and rotates the low noise block down converter or the feedhorn to compensate for a skew angle when the satellite signal received by the feedhorn is a linearly polarized wave; a polarizer that receives a linearly polarized signal and a circularly polarized signal of the satellite signal; and a polarizer rotating device that rotates the polarizer when the satellite signal received by the polarizer is a circularly polarized wave. In such a simple structure, the linearly polarized wave and the circularly polarized wave are all received to be processed.
