Claim Text:
1. A method for installing an antenna device comprising: one dipole antenna exciter including a first columnar sub-conductor, a second columnar sub-conductor and a first main columnar conductor; and another dipole antenna exciter including a second main columnar conductor and a U-shaped conductor bent into a U-shape; wherein the method comprises: a lower-side-columnar-conductor installing process including: a lower-side-columnar-conductor electrical connecting process of connecting electrically the first columnar sub-conductor and the second columnar sub-conductor with the first main columnar conductor; an upper-side-columnar-conductor installing process of fastening a base end portion of the second main columnar conductor to an opposite surface of an upper center dielectric spacer, mounted on a tip portion of the first main columnar conductor, to a surface mounted on the tip portion of the first main columnar conductor, and of setting up the second main columnar conductor; an upper-dielectric-spacer mounting process of mounting a first upper dielectric spacer on a tip portion of the first columnar sub-conductor, and mounting a second upper dielectric spacer on a tip portion of the second columnar sub-conductor; an U-shaped-conductor fastening process in which, an one end of the U-shaped conductor bent in the U-shape is fastened to an opposite surface of the first upper dielectric spacer to a surface mounted on the tip portion of the first columnar sub-conductor, another end of the U-shaped conductor is fastened to an opposite surface of the second upper dielectric spacer to a surface mounted on the tip portion of the second columnar sub-conductor, and a center portion of the U-shaped conductor is fastened to a tip portion of the second main columnar conductor; and a wiring process of connecting electrically one line of a power feeding portion to the second main columnar conductor, and connecting electrically another line of the power feeding portion to the first main columnar conductor.
