Abstract
PURPOSE:To prevent radio wave troubles reliably and economically by reflecting a radio wave by a certain metallic fence on a side of a structure. CONSTITUTION:A metallic fence 2 having a slit 2a is obliquely mounted on a structure 1. When a mounting angle thereof is adjusted, an injecting radio wave is reflected by the fence 2 in a direction different from that of a signal receiving antenna, whereby radio wave troubles such as TV monitor ghosts caused by the structure can be prevented. By using the metallic fence which has a slit and which is easy to prepare, light, wind pressure resistant, and easy to handle, radio wave troubles can be prevented reliably as well as economically.
