1. A radio wave monitoring apparatus comprising:
a television receiver which is capable of receiving a radio wave in a television broadcast frequency band and generates reception quality information; and
a wireless communication device which is capable of establishing communication in an area to be monitored and a wider area than the area to be monitored and transmits the reception quality information, wherein
operation of a circuit block that is redundant to radio wave monitoring in the television receiver is stopped,
only when an input signal indicates a great change, the circuit block is rendered operative to acquire the reception quality information, and
an AGC signal is monitored, and when the AGC signal changes by an amount equal to or greater than a predetermined value, the reception quality information is acquired.
