Abstract

PURPOSE:To make easy the switching of directivity and to make compact the device at nonuse, by enabling to assemble and disassemble side frames freely, where auxiliary antenna conductors are fitted, and a ceiling plate where loop shape main antenna conductors are fitted. CONSTITUTION:A ceiling plate 10 of a stand ST mounting a television receiver TV has a plurality of selectable power feeding points around an insulation plate 11, and each feeding point is connected to each switch of a swtich board 12 via a feeding wire and main antenna conductors M are fitted. On the other hand, opposing channel-shaped side frames 13, 13' are connected to the main antenna conductor M on the surface of insulation frames 14, 14' to be connected with auxiliary antenna conductors A2, E, H and C2, F, G forming loop, and the surface of insulation rods 16, 16' is fitted with rids 15, 15' fitted with conductors B2, D2 and are connected to the conductos E, F and H, G and further connected to the conductor M to form the loop.
