PROBLEM TO BE SOLVED: To facilitate the adjustment of an installation position at the time of installing the antenna of a communication equipment. SOLUTION: A radio signal received by the antenna 1 is supplied to a reception level evaluation part 3 through a receiver 2. The reception level evaluation part 3 evaluates the signal level of the received radio signal in five stages and supplies the evaluated result to a light-emitting element control part 5. The light-emitting element control part 5 displays the supplied evaluated result by using light-emitting elements 6-10. A display device constituted by the light- emitting elements 6-10 is integrally constituted with the antenna. A mode switching part 14 has a function for switching a mode to a test mode by which the radio signal of a prescribed level is compulsorily transmitted to a communication opposite party at the time of installing the antenna 1. A person who installs the antenna 1 can adjust the installation position while the reception level displayed on the display device is recognized. |
