Abstract

PURPOSE:To make the directive bearing and the directional pattern of an antenna optimum according to channel selection by giving a directivity set signal according to a selected channel or a selected channel frequency to the directivity control means of the antenna in respect to the broadcast radio wave receiving antenna unit. CONSTITUTION:The signal to set the directive bearing of a desired channel is transmitted from antenna control transmitter 15. This signal is received by photo diode 13 of antenna control receiver 38 and is supplied to data register 72 through the second discrimination circuit 67, and directivity set signals Qa to Qc of register 72 are supplied to decoder 32, and an optimum receiving is detected by antenna control circuit 36 and directivity control means 37 and is written in memory unit 70. Next, when a desired channel selection signal is transmitted from transmitter 15, this signal is received by television receiver 60 to select a channel; and simultaneously, this signal is received by antenna control receiver 38, and directivity set signals Qa-Qc are read out from memory unit 70 to control directivity of the antenna.
