<P>PROBLEM TO BE SOLVED: To provide a radio path display board capable of performing obstacle confirmation work by visually specifying a radio propagation direction at least from two points, and a method for confirming the radio path. <P>SOLUTION: A radio path display board 10 for confirming whether or not there is an obstacle in a radio path before/after reflection at a relay point reflecting a radio wave by a reflector for relaying includes: a tabular body 11; and two L-shaped fixed metal materials 12 that are attached to the body 11 for mounting the radio path display board onto the reflection surface of the reflector. The body 11 is formed with, from the surface of the body 11 through the rear surface of the body 11, an elongated left-direction display hole 11<SB POS="POST">L</SB>for specifying the incident direction of the radio wave; and an elongated right-direction display hole 11<SB POS="POST">R</SB>for specifying the reflection direction of the radio wave. <P>COPYRIGHT: (C)2013,JPO&INPIT |
