Abstract

PURPOSE:To keep a high F/B ratio and thus to prevent the ghost fault by constituting the paired reflector conductor provided in parallel and symmetrically to the radiator with the reflector and the radiator assembled by the value higher than the column frequency and then giving the control to the length of and the distance between the reflectors. CONSTITUTION:Paired reflector bars R1/R1', R2/R2', R3/R3' and R4/R4' which are distributed in parallel and symmetrically to radiator A are constituted with the reflectors and radiators assembled by the value higher than the folumn frequency. The column frequency means the frequency among the frequency bands desiring preservation of a high F/B ratio. And for instance, the column frequency of paired R1 and R2 shows the video frequency of channel 1. In order to keep a high F/B ratio, the control is given to the length of and the distance between pairs R1-R4 and R1'-R4'.
