Abstract

PURPOSE:To secure the easy alteration for the antenna's directivity by compounding the signals sent from plural number of antennas along with use of the phase-shift circuit applying the variable capacity diode. CONSTITUTION:The signals sent from antenna 7' among the signals from two antennas 7 and 7' which are not shown in the diagram are separated into the high- and low-channel signals through filter 81 and then composed again by filter 84 and via corresponding phase-shift circuits 88 and 87 each. Circuits 88 and 87 are constituted with the variable capacity diodes, and the amount of their phase shift is controlled by voltage control circuit 10 which is selected by control switch 9 provided in correspondence to the selection switch or the like. The output of filter 84 and the signals sent from antenna 7 and via fixed attenuator 85 are connected to the antenna terminal of the TV picture receiver or the like via mixer circuit 86.
