PURPOSE:To prevent noise sent via a power supply line from giving a failure on a receiver via an antenna circuit, by fitting a line which leads lightning induced on the antenna to the ground side of the power supply, to an antenna terminal board with a gap. CONSTITUTION:An antenna 4 is connected to a terminal 5 of the antenna terminal board 1 having conductor sections 2, 3 insulated mutually and led to a television receiver 11 via capacitors 8-10 and a terminal 7. One end of the line 16 leading the lightning to the ground of the power supply is fitted to a terminal 6 provided to the conductor section 2 independently via a 0.5mm. circular gap A, and the other end is connected to a terminal 15 of the power supply board 12. This terminal 15 is provided apart by 6mm. from the ground terminal 14 of the commercial power supply. Further, the board 12 is provided apart by >=6mm. from the conductor section of the receiver 11. |
