PROBLEM TO BE SOLVED: To provide a directional antenna easy to install in any specified direction. SOLUTION: The directional antenna 1 is provided with a finder scope 4 having a sighting axis S approximately parallel to the antenna pointing direction R. In the installing work, a worker peeps the finder scope 4 to take aim at the specified point of a party's directional antenna 1 and tightens bolts 3d, 3f to fix the position of the antenna 1. Since the antenna pointing direction R and the sighting axis S are approximately parallel, these directional antennas' pointing directions R are aligned by setting their sights.
