摘要：
An SHF-band receiving apparatus is used for demodulating a signal received by an antenna and input through a cable by using an indoor receiving unit which comprises; demodulation means for demodulating an input signal supplied thereto through the cable; detection means for detecting a detection signal representing the direction of the antenna from a demodulated signal output by the demodulation means; and output means for generating a modulated signal for displaying information on the direction of the antenna by modulation of a carrier signal based on the detection signal produced by the detection means and for outputting the modulated signal through the cable to the antenna side.
